cannot change value of texbox w/in datagrid after first bind

Michael via .NET 247

I have a datagrid with the columns defined in the aspx
<columns>
<asp:TemplateCo lumn HeaderText="Hou rs" ItemStyle-Width="1%"ItemS tyle-HorizontalAlign ="Center">
<ItemTemplate >
<asp:TextBox Columns="2" EnableViewState ="False" ID="Hours"Runat ="server"></asp:TextBox>
</ItemTemplate>
</asp:TemplateCol umn>
...
</columns>

I have other bound columns that display the correct data so Iknow the dataset is ok.
Here's the problem. In
dgTest_ItemBoun d(...) Handles dgTest.ItemData Bound
I have:
CType(e.Item.Ce lls(3).FindCont rol("Hours"), TextBox).Text =drv("TotalHour s").ToString

When I make the first request, the hours txtbox is populatedcorrec tly. Any rebinding after that, the value is unchanged. Ifthe box initially was filled with '20' and the grid was reboundto contain 0 hours, 20 remains, even though another bound columncontainin g 'TotalHours' DOES change. This is very strange. Anyideas?

I've already tried things with viewstate on/off for the dg andtxtbox. I've already tried adding the textbox controldynamica lly and clearing it, etc. No good.

I also tried using <asp:textbox><% # eval....contain er...%></asp:textbox> but you can't do that for other reasons.

Any help if appreciated. Thank you.

Hi,

Sounds like you are filling the dataset even when you are posting back.

I've already tried things with viewstate on/off for the dg and txtbox. I've

No good.

The easy way to turn off automatic updates for Windows 10/11

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
