How to change a Radgrid column value after binding? - sql

Question

I have a Radgrid and I bind it with SqlAdapter. My problem is that I want to change just one column's value. Is that possible?
My column name is IsShadow and it binds true or false. I cannot change it. If value is false or true, I change column text appearence, not database update.
Code I've tried
foreach (Telerik.Web.UI.GridDataItem dataItem in gridShadow.MasterTableView.Items)
{
bool flag = Convert.ToBoolean(dataItem.GetDataKeyValue("IsShadow"));
GridEditableItem editedItem = dataItem as GridEditableItem;
if (!flag)
{
TableCell tableCell = editedItem["IsShadow"] = ???
}
}
Thank you.

Answer 1

Please try with the below code snippet and let me know if any concern.
// Normal Mode
if (e.Item is GridDataItem)
{
GridDataItem item = (GridDataItem)e.Item;
item["IsShadow"].Text = "Your new text";
}
// Edit Mode
if ((e.Item is GridEditableItem) && (e.Item.IsInEditMode))
{
GridEditableItem editItem = (GridEditableItem)e.Item;
(editItem["IsShadow"].Controls[0] as TextBox).Text = "Your new text";
}

You probably need a GridTemplateColumn
In the ItemTemplate you will check the value of IsShadow and display some text, but in EditItemTemplate you would probably need to just have a checkbox for true/false.
<telerik:GridTemplateColumn HeaderText="Is Shadow" UniqueName="TemplateColumn">
<EditItemTemplate>
<asp:CheckBox id="editChkBox" runat="server"
Checked='<%# Bind("IsShadow") %>'>
</asp:CheckBox>
</EditItemTemplate>
<ItemTemplate>
<asp:Lable id="lblIsShadow" runat="server"
Text='<%# Convert.ToBoolean(Eval("IsShadow")) == true ? "it is shadow" : "Not shadow" %>'>
</asp:CheckBox>
</ItemTemplate>
</telerik:GridTemplateColumn>
