I am using Templates in GridView, but now I have to change the "HeaderText" of each column from code behind. I don't have <HeaderTemplate> so therefore I cannot use FndControl() in header row.
Is there a way to change the HeaderText of each colum without using <HeaderTemplate>
Here are the templates of the GridView which I am using

I have a webform with a DetailsView control. In the DetailsView, I would like to update the headertext (showing field names) to a "friendly name"
I also have a cross-reference table which has a field name with a matching friendly name.
Is there some code to get my DetailsView control to look up the field name, and then display the friendly name on my form.
I have a gridview and I would like to be able to programatically change the HeaderText of it's columns (probably in the DataBinding event). I know this can normally be achieve with something like this:
myGrid.Columns[0].HeaderText = "My Header Text";
However, the gridview in question is actually nested within another gridview (via template column). So I can't access it directly. I'm trying to use the FindControl method to access it, but so far that isn't working.
I'm trying to programaticaly change the 'headerText' property of a GridView boundfield.
[Code]....
Apparently all goes weel, because i ca see, in a a debug session, the control initial value, and after i change it, the value changes.
Is tehre anyway to set the HeaderText dynamically on a gridview? I'm trying the below, it kind of works, but the problem is on the initial load nothing shows up, but when I postback then the new text populates:
grdvMyTest.HeaderRow.Cells[5].Text = GetTheCalculatedDate();
I've tried that in both Page_Load and grdMyTest_Load, but same thing happens in both. When the page initial loads the column header text is blank, when I click something causing a postback it pops up. I don't have a IsPostBack check around that line, so it should be running regradless. I'm guessing I'm doing it at the wrong event, either too eariler or too late.
I need to set the HeaderText of GridView BoundField in codebehind file based on a flag at runtime.
I tried setting the column name as
e.Row.Cells[0].Text = "XXXX";
It is worked out but not able to sort that column.
here my requirement is to set the HeaderText programmatically in codebehind and able to sort the column.
Actually i want that HeaderText of gridview should be as column name of datatable, which i assign to that perticular column of gridview.
I have templatefield in that column and AutoGeneratedColumn is false
I have a GridView whose AutoGenerateColumns="False". However, I don't want to statically specify the HeaderText for the columns in HTML markup. Rather I'd like to set the HeaderText to be the name of the underlying SQLDataSource column name. How can I do this?

I am using VS2008.I am binding dynamic datatable to gridview. I have few dropdowns and textboxes in gridview.
I have dropdownlist(ddlTrCodeNw_)in gridview foooter template. Based on the selection of Trcode value few controls will be enabled,disabled,visible,hide. in gridview.
<asp:GridView ID="gvAPPost" runat="server" Width="100%" ShowFooter="true"
AllowPaging="true" AutoGenerateColumns="false"
onrowcommand="gvAPPost_RowCommand"
onrowdatabound="gvAPPost_RowDataBound"
>
<Columns>
<asp:TemplateField HeaderText="Discount %" Visible="false">
<FooterTemplate>
<asp:TextBox ID="txtDiscountPerNw" runat="server" Width="40px" Enabled="false" Visible="false" ></asp:TextBox >
</FooterTemplate>
<ItemTemplate>
<asp:TextBox ID="txtDiscountPer" runat="server" Width="40px" Enabled="false" Visible="false"></asp:TextBox >
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
Intially I set TemplateField HeaderText also Visible="false".
so i have written the condition in ddlTrCodeNw_SelectedIndexChanged.
Now when
if(ddlTrCodeNw.SelectedValue=="24")
{
txtDepstNw.Enabled = true;
txtDepstIncNw.Enabled = true;
txtCrdtNw.Enabled = false;
txtCrdtIncNw.Enabled = false;
lblDiscTrcodeNw.Visible = true; // I want to show this TemplateField HeaderText also when i need.
}
I can I show TemplateField HeaderText also whenever i need.
I have a grid that is built as well as populated dynamically through c# code. The grid has 3 columns(3 bound fields). And data is being populated in those bound fields through c# code programatically.
Elaborating my question: I have 3 bound field columns(col1, col2 & col3) . I have to increase the rowspan of col2 and col3 headertext's to 2 i.e I want the col2 and col3 header texts to span across two row cells. But the col1 header text should span across just 1 row. And the extra rowscell that is created under col1 due to the increase in the rowspans (of col2 and col3 boundfield headertexts) should be populated with some random text, i.e something like XXXXX

I'm trying to change one section in code from DataGrid format to GridView format. The reasoning is that the sample application that was displayed was using a DataGrid even though it should have been using a Gridview for 2.0 and above. Most of it shows up without an error except one line in 3 lines which are pretty much the same. I bolded them and just want to know how do I re-write them for the Gridview?

I have a gridview that loads with a new datasource on button click event. On the gridview (which is located in a table columm incidentally) are 2 columns, a descriptor and a checkbox. The problem is that after postback, the column widths change, the checkbox column expands and the other column contracts. Is there a way to keep the gridview column sizes the same after postback?
View 2 RepliesI cannot figure out why HeaderText or validation controls always fallback to default culture - even though rest of the controls are in correct culture.
I have a GridView with HeaderText specified in this way>
<asp:BoundField DataField="totalSales" HeaderText="<%$ Resources:Strings,TotalSales %>" />
In the same way I have validation controls and they can't be localized.
Only this syntax does work: <%= Resources.Strings.Payments %>
I set different culture in Master page using this statement in Page_Init
Me.Page.Culture = "pl-PL"
Me.Page.UICulture = "pl-PL"
I'm trying dynamically to change the HeaderText of one of my DataGrid's columns but have some problem.
I'm making the change on button click event.
At the first click nothing happened, but at the second click the change is made correctly.
Why only at the second click the change is made?

I have a gridview in which I have several editable fields. The user wants a non-editable field to be modified if another field is modified in the same row. e.g. if Age>=65, Status should ="Retired"
I am using the following demo: [URL]
to create a bulk edit gridview so some columns are automatically editable and others aren't, with a single update button. I can set Status="Retired" in the xml generated, or as a rule in database table. But I'd like the status field in the gridview to change when Age is modified and to be shown to user before they press the single Update button. I'm using update panels and ajax on the page also.
