I have a table adapter and it is querying the database base on table id. The result of the query i want to show in textboxes. How can do do that? Some help please.
basically iterate through the Rows of the table then pick the individual cells of each row you want to assign to the textboxes.
A much easier method to display the data, is through the DataGridView, which can bind to the table and show the data automatically.

I have a datagridview with records with given data from a datasource connected to a SQL Database. What I want to do is to select a row and have a combobox pull related data for a given field from the datagridview and have it populate the combobox. What I want to do is have the combobox be filtered by a field in the datagridview.
I am able to write a SQL statement to pull ALL data from a field in SQL and populate the combobox but I cannot get that to correlate with a given field from the datagridview and I do not think that is possible but I could be wrong.
Anything helps!
I have a temporary table that is created from a series of query with a VBA code. The name and number of fields in the table changes with the results of the queries.
Right now I simply open the table with DoCmd.OpenTable.
What I would like to do is display the table in a form so I can include some buttons for example to allow the user to export the table.
I tried a listbox but the formatting was not good and I can't add horizontal scroll bar to see all fields.
I tried a subform populated from the table, but it would not adapt to the changes of the table (fields and numbers).
Any Idea of what can I do next ?
the subform seems to be a good idea. When your table is ready to be shown, you can assign it to a subform object via Me.subFormName.SourceObject = "Table.tableName"
(of cource "subFormName" and "tableName" have to be replaced by the actual names of the subform and the table)
Instead of filtering the data filtered on the query, is there a way to tell report generator not to display some rows in a table. Example have something like display row if [id]>5?
Yes, on the row itself, there is a "Hidden" property, so you would set an "expression" on that row filtering for any ID <= 5 (remember, it's a "hidden" property, not a "shown" property)
I have two tables that are related to each other in a 1-1 relationship (each row in the main table has exactly one corresponding row in the second table).
I also have a winform in which I'd like to show the main table in a datagridview, and for each row selected in the grid to show the fields of the corresponding row of the second table in various textboxes below the grid.
I know how to bind a datagridview to a datatable. But I'm not sure about binding several textboxes to a single row in the related datatable. I don't know what is the best way to implement it.
I'm writing in VB.Net (but can read some code in C#), using VS2008.
Any help, hints or ideas will be welcomed. Thanks.
Best way to do it is that instead of using two tables, use a join and get result in a single table, bind that table to gridview, and hide columns which you don't want to display to user.
And then use cell click event of gridview and then get the index of selected row and then use
txtBoxName.Text = GridViewName["col_name",e.RowIndex].Value.ToString();
I am fetching data in from an SQL table using a DataSet in VB.Net. When there is data in table, it displays the data properly in the grid, but when there is no data in the table, it only shows the UltraGrid's basic view.
How can I display the column names of the table as headings of the UltraGrid even when there is no data in Table?
Thanks for the reply, but I think the problem that JD is having is a bit different from mine - in my application the data got fetched properly from SQL Server. My problem is that when there is no data in the table, I want to display the columns of the table as the headings of the grid with 0 rows. This is not happening.
It just shows a message box saying that no data is found, and the UltraGrid shows as it does by default in the application.
This is discussed in this Infragistics forum thread.
Do you know what the headers of the columns will be or is it dynamic based on the data in the table? If you know beforehand you can create the columns with the appropriate headers in an empty dataset and assign that to the grids datasource.
I notice this same behavior when I manually create a datatable and assign it as the grid's datasource. If the data table is empty, all the column header info that was previously set on the grid is lost. My solution to this was to never actually give it an empty table, if I have no rows in my table, at least have all the columns defined.
DataTable table = new DataTable("fooTable");
table.Columns.Add("fooCol1", typeof(long));
table.Columns.Add("fooCol2", typeof(string));
table.Columns.Add("fooCol3", typeof(bool));
myUltraGrid.DataSource = table;
By never setting the grid to an empty table, you keep your header info.
