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'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 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 looking for the best way (Performance) to do gridview columns formating RunTime /Dynamic depending on the datatable Columns type ,I want to bind the datatable to a gridview and format the Date columns to short date, and currency columns formatted with comma ex 10,000.00 inplace 100000.00 at datatable the column type is double run time (without converting them to String) since I do a filtering and sorting at these columns.
View 3 RepliesIs 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 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 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.
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've built a User Control that contains a ListView. To make it work I need to pass to it a DataTable. The columns of this DataTable need to have particular names that match up with what the ListView is expecting. I have a large DataTable that I need to massage/convert over to this different format. To do that I need to filter out columns and rename the column names. The actual data in the DataTable doesn't need to change. Is there a good way to do this without actually instantiating a new DataTable and copying the data from the large DataTable into it?

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: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

gvOff.DataBind();
gvOff.Columns[0].HeaderText = "ZZZZZZZZ";
gvOff.Columns[1].HeaderText = "YYYYYYYY";
gvOff.Columns[2].HeaderText = "XXXXXXXX";
Header count is correct.
AutoGenerateColumns: Flase/True ( i tried both)
If i remove the gvOff.Columns[index].HeaderText portions, GridView works fine, but when i put the gvOff.Columns[0].HeaderText, i get the exceptional error.
, i couldn't solve it. If you need further info, inform me.
EDITED:
Hold on! I commented the HeaderText portion and tested
int i = gvOffer.Columns.Count;
I found count is 0 eventhough the columns print out with DataBind()... Why?
NOTE: AutoColumn in this case is set to true. I guess i will have to edit the column
names from DataTable.
I have a Gridview with ID "GVSeasonsOfResort" which has selectable rows.
One of the fields in that gridview is RSLinkID which is an ID field of the table from which ths SQLDataSource driving the gridview gets its data.

How is it possible to change the displayed order of columns from a DataTable?
For example, dataTable "dt" contains two columns "a" and "b". I bind it to a GridView like this:
gridView.DataSource = dt;
gridView.DataBind();
But I'd like the GridView to display "b" first (leftmost).
Important point: I'm using this to export to Excel and there's no actual output to screen, using:
HtmlTextWriter htw = new HtmlTextWriter(sw);
gridView.RenderControl(htw);

View 1 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"
