My code look like below.
protected void btnApprove_Click(object sender, EventArgs e)
{
if (id == "Button2")
{
string sql = #"update AdjTranSeqDetails set Approver1Status = 'Rejected',finalStatus='Rejected' ,updatedtime = GETDATE(),Approver1Comment ='{1}',modifieduser = '{2}' where TranSeq ={0}";
sql = String.Format(sql, tbxTranSeq.Text, TextBox2.Text, Master.CurrentUser);
string sql2 = #"INSERT INTO AdjTranSeqDetailsHistory SELECT * FROM AdjTranSeqDetails WHERE tranSeq={0}";
sql2 = String.Format(sql2, tbxTranSeq.Text);
string sql3 = #"delete from AdjTranSeqDetails where tranSeq={0}";
sql3 = String.Format(sql3, tbxTranSeq.Text);
if (dba.SqlUpdate(sql, ref ex, ref rowCt) || dba.SqlInsert(sql2, ref ex, ref rowCt) ||dba.SqlDelete(sql3, ref ex, ref rowCt))
{
string sscript = "<script language=\"Jscript\" > ";
if (Master.PageMode == "View")
{
sscript += "if (window.opener && !window.opener.closed) ";
sscript += "{window.opener.DoSearch();}";
}
sscript += "window.opener='x';self.close();";
sscript += "</Script>";
Page.ClientScript.RegisterStartupScript(this.GetType(), "SelfClose", sscript);
}
}
updateapp();
GetBillTranInfo();
}
Like Button2, like have 10 button. If one if condition function done I need to close the window and need to reload the page. Can I do like this?
I have tried like above but that is not working for me.
In my user controls, after updating data I do:
Response.Redirect(Request.RawUrl);
That ensures that the page is reloaded, and it works fine from a user control. You use RawURL and not Request.Url.AbsoluteUri to preserve any GET parameters that may be included in the request.
You probably don't want to use: __doPostBack, since many aspx pages behave differently when doing a postback.

I have a program that loads a checked list box, then the user selects the items they want and selects a button to say they are done. The checked items are read in a contiguous string with a newline "\n" at the end of each string added. My problem is everything works ok except the newline "\n", and I don't know why.
Code
private: System::Void bntSelected_Click(System::Object^ sender, System::EventArgs^ e) {
int numSelected = this->checkedListBox1->CheckedItems->Count;
if (numSelected != 0)
{
// Set input focus to the list box.
//SetFocus(lstReceiver);
String^ listBoxStr = "";
// If so, loop through all checked items and print results.
for (int x = 0; x < numSelected; x++)
{
listBoxStr = listBoxStr + (x + 1).ToString() + " = " + this->checkedListBox1->CheckedItems[x]->ToString() + "\n";
}
lstReceiver->Items->Add(listBoxStr);
}
}
The string is being formed correctly, but the ListBox control doesn't show newlines in its list items - each item is pushed onto a single line. You can see this by debugging, or by adding a Label to the form with AutoSize set to false - the label will show the newline(s) in the string properly.

Instead of ‘\n’, try ‘\r\n’. This may be a windows thing.
The Download command is showing in front of all the rows, I want to show it to only those rows having PDF file attached in the database.
protected void gvupdationsummary_SelectedIndexChanged(object sender, EventArgs e)
{
SqlConnection con = new SqlConnection(st);
con.Open();
SqlCommand com = new SqlCommand("select [name],[data] from [Pragati].[dbo].[Pragati_Status_Updations] where Pragati_no=#Pragati_no", con);
com.Parameters.AddWithValue("Pragati_no", gvupdationsummary.SelectedRow.Cells[3].Text);
SqlDataReader dr = com.ExecuteReader();
if (dr.Read())
{
Response.Clear();
Response.Buffer = true;
//Response.ContentType = dr["type"].ToString();
Response.AddHeader("content-disposition", "attachment;filename=" + dr["name"].ToString());
Response.Charset = "";
Response.Cache.SetCacheability(HttpCacheability.NoCache);
Response.BinaryWrite((byte[])dr["data"]);
Response.End();
}
else
{
// ...
}
}
The code that you show seems to do the actual PDF download already. There is nothing you can do there to prevent the showing of a download button or link.
Instead you need to change the SQL query that provides data for gvupdationsummary, and add a column such as HasPDF there, like this:
SELECT /* your columns */ ,
CAST(CASE WHEN [data] IS NULL THEN 0 ELSE 1 END AS BIT) AS HasPDF
FROM ....
WHERE ....
Then in your grid rendering code you can use the boolean value of HasPDF to decide if the Download button should be shown.
Using this approach you don't needlessly transfer all PDF binary data from your database to your application, every time the grid is being rendered.
You can use SQLDataReader's IsDBNull method to see whether the column contains non-existent or missing values.
ind idx = dr.GetOrdinal("data");
if (!dr.IsDBNull(idx))
{
// set download link on to response.
}
else
{
}
I'm successfully creating a Sharepoint List (named "XMLToPDFTestList"), which I can see via Site Actions > View All Site Content, but my attempts to add columns to the list has so far proven fruitless.
Here is how I'm trying to do it:
private void ProvisionallyCreateList()
{
SPWeb mySite = SPContext.Current.Web;
// Check to see if list already exists; if so, exit
if (mySite.Lists.TryGetList(listTitle) != null) return;
SPListCollection lists = mySite.Lists;
SPListTemplateType listTemplateType = new SPListTemplateType();
listTemplateType = SPListTemplateType.GenericList;
string listDescription = "This list is to hold inputted vals";
lists.Add(listTitle, listDescription, listTemplateType);
// Now add a couple of columns
SPList list = lists["XMLToPDFTestList"];
string faveNum = list.Fields.Add("favoriteNumber", SPFieldType.Text, false);
list.Fields[faveNum].Description = "favorite number";
list.Fields[faveNum].Update();
string faveCol = list.Fields.Add("favoriteColor", SPFieldType.Text, false);
list.Fields[faveCol].Description = "favorite color";
list.Fields[faveCol].Update();
}
This is all I see when I click "XMLToPDFTestList":
My "gut feeling" is that this line:
SPList list = lists["XMLToPDFTestList"];
...is not right/not specific enough. Instead of "XMLToPDFTestList" it should be something else/prepend something, or so. But what, exactly?
It was, as is so often the case, "my bad" (YMMV?).
The problem is in my list item creation code which, because I was not assigning anything to the default/inherited "Title" field, made it appear to me (as in the scream shot above) that no item was being added.
Once I fixed the code, by changing this:
private void SaveInputToList()
{
using (SPSite site = new SPSite(siteUrl))
{
using (SPWeb web = site.RootWeb)
{
SPList list = web.Lists[listTitle];
SPListItem SPListItemFaveNum = list.Items.Add();
SPListItemFaveNum["favoriteNumber"] = "7"; //inputtedNumber; TODO: Once 7 and teal are being saved and retrieved successfully, assign the var vals - will need to declare the controls created in CreateChildControls() globally
SPListItemFaveNum.Update();
SPListItem SPListItemFaveHue = list.Items.Add();
SPListItemFaveHue["favoriteColor"] = "teal";
SPListItemFaveHue.Update();
}
}
}
...to this:
private void SaveInputToList()
{
using (SPSite site = new SPSite(siteUrl))
{
using (SPWeb web = site.RootWeb)
{
SPList list = web.Lists[listTitle];
SPListItem spli = list.Items.Add();
spli["Title"] = "Write the Title";
spli["favoriteNumber"] = "7";
//SPListItemFaveNum.Update();
//SPListItem SPListItemFaveHue = list.Items.Add();
spli["favoriteColor"] = "teal";
//SPListItemFaveHue.Update();
spli.Update();
}
}
}
...it works fine: an item is added with all three values (Title, favoriteNumber, and favoriteColor).
I was assuming the item wasn't being created because "Title" was blank, and I was calling update on each SPListItem, whereas all I really need to do is call Update once, and on one SPListItem, not multiple.
So I have this project at school to create a game "Guess the number". I am trying to loop a DialogResult using a switch statement and a while loop. I tried many possibilities but I go into a infinite loop. Just to know I am a beginner.I would really need some help here if possible. This is my code. Thanks in advance.
private void btnStartTheGame_Click(object sender, EventArgs e)
{
int guessTheNumber = Convert.ToInt32(txtNumberGuess.Text);
DialogResult dialogResult = MessageBox.Show("Is number" + number.ToString() + " you are thinking about?", "Answer the question!", MessageBoxButtons.YesNo);
switch(dialogResult)
{
case DialogResult.No:
while (dialogResult == DialogResult.No)
{
Random newNumberGenerator = new Random();
number = newNumberGenerator.Next(0, 101);
MessageBox.Show("Is number" + number.ToString() + " you are thinking about?", "Answer the question!", MessageBoxButtons.YesNo);
}
break;
case DialogResult.Yes:
if (dialogResult == DialogResult.Yes)
{
MessageBox.Show("Congratulation! You guessed the number!!");
break;
}
break;
}
You need to load the new result of the dialog.
int guessTheNumber = Convert.ToInt32(txtNumberGuess.Text);
DialogResult dialogResult;
do
{
Random newNumberGenerator = new Random();
number = newNumberGenerator.Next(0, 101);
dialogResult = MessageBox.Show("Is number" + number.ToString() + " you are thinking about?", "Answer the question!", MessageBoxButtons.YesNo);
} while (dialogResult == DialogResult.No);
MessageBox.Show("Congratulation! You guessed the number!!");
The do loop will execute the code first, and then check the condition. THis will also prevent having the same piece of code at different places, meaning the same.
I have a few tables in a c# application I'm currently working on and for 4/5 of the tables everything saves perfectly fine no issues. For the 5th table everything seems good until I reload the program again (without modifying the code or working with a seperate install so that the data doesn't go away) The 4/5 tables are fine but the 5th doesn't have any records in it after it has been restarted (but it did the last time it was running). Below is some code excerpts. I have tried a few different solutions online including creating a string to run the sql commands on the database manually and creating the row directly as opposed to the below implementation which uses a generic data row.
//From main window
private void newInvoice_Click(object sender, EventArgs e)
{
PosDatabaseDataSet.InvoicesRow newInvoice = posDatabaseDataSet1.Invoices.NewInvoicesRow();
Invoices iForm = new Invoices(newInvoice, posDatabaseDataSet1, true);
}
//Invoices Table save [Works] (from Invoices.cs)
private void saveInvoice_Click(object sender, EventArgs e)
{
iRecord.Date = Convert.ToDateTime(this.dateField.Text);
iRecord.InvoiceNo = Convert.ToInt32(this.invoiceNumField.Text);
iRecord.Subtotal = (float) Convert.ToDouble(this.subtotalField.Text);
iRecord.Tax1 = (float)Convert.ToDouble(this.hstField.Text);
iRecord.Total = (float)Convert.ToDouble(this.totalField.Text);
iRecord.BillTo = this.billToField.Text;
invoicesBindingSource.EndEdit();
if (newRecord)
{
dSet.Invoices.Rows.Add(iRecord);
invoicesTableAdapter.Adapter.Update(dSet.Invoices);
}
else
{
string connString = Properties.Settings.Default.PosDatabaseConnectionString;
string queryString = "UPDATE dbo.Invoices set ";
queryString += "Date='" + iRecord.Date+"'";
queryString += ", Subtotal=" + iRecord.Subtotal;
queryString += ", Tax1=" + iRecord.Tax1.ToString("N2");
queryString += ", Total=" + iRecord.Total;
queryString += " WHERE InvoiceNo=" + iRecord.InvoiceNo;
using (SqlConnection dbConn = new SqlConnection(connString))
{
SqlCommand command = new SqlCommand(queryString, dbConn);
dbConn.Open();
SqlDataReader r = command.ExecuteReader();
dbConn.Close();
}
}
dSet.Invoices.AcceptChanges();
}
//Invoice Items save [works until restart] (also from Invoices.cs)
private void addLine_Click(object sender, EventArgs e)
{
DataRow iRow = dSet.Tables["InvoiceItems"].NewRow();
iRow["Cost"] = (float)Convert.ToDouble(this.costField.Text);
iRow["Description"] = this.descriptionField.Text;
iRow["InvoiceNo"] = Convert.ToInt32(this.invoiceNumField.Text);
iRow["JobId"] = Convert.ToInt32(this.jobIdField.Text);
iRow["Qty"] = Convert.ToInt32(this.quantityField.Text);
iRow["SalesPerson"] = Convert.ToInt32(this.salesPersonField.Text);
iRow["SKU"] = Convert.ToInt32(this.skuField.Text);
dSet.Tables["InvoiceItems"].Rows.Add(iRow);
invoiceItemsTableAdapter.Adapter.Update(dSet,"InvoiceItems");
PosDatabaseDataSet.InvoiceItemsDataTable dTable = (PosDatabaseDataSet.InvoiceItemsDataTable)dSet.InvoiceItems.Copy();
DataRow[] d = dTable.Select("InvoiceNo=" + invNo.ToString());
invoiceItemsView.DataSource = d;
}
Thanks in advance for any insight.
UPDATE: October 17, 2011. I am still unable to get this working is there any more ideas out there?
you must execute your Sql Command in order to persis the changes you made.
using (SqlConnection dbConn = new SqlConnection(connString))
{
dbConn.Open();
SqlCommand command = new SqlCommand(queryString, dbConn);
command.ExecuteNonQuery();
dbConn.Close();
}
The ExecuteReader method is intended (as the name says) to read the data from a SQL table. You need to use a different method as you can see above.
We need some more info first, you haven't shown the case where your code fails.
Common mistakes on this kind of code is calling DataSet.AcceptChanges() before actually committing the changes to the database.
Second is a conflict between databound data through the binding source vs edits to the dataset directly.
Lets see the appropriate code and we can try and help.
Set a breakpoint after teh call to invoiceItemsTableAdapter and check the InvoiceItems table for the row you have added. Release the breakpoint and then close your app. Check the database again. I would say that another table may be forcibly overwriting the invoice item table.
