Hi all,
I am using template column to add checkbox in my grid.But when I check status of checkbox on button click it always returns status=FALSE

why this is so? Here is my code

protected void Page_Load(object sender, EventArgs e)
{
int [] arr;
arr = new int[4] {1,2,3,5};
GridView1.DataSource=arr;
GridView1.DataBind();

}
protected void Button1_Click(object sender, EventArgs e)
{
int i;
for (i = 0; i < GridView1.Rows.Count; i++)
{
bool chk = ((CheckBox)GridView1.Rows[i].FindControl("Admin")).Checked;
if (chk)
{
//some code
}
}
}

<asp:gridview id="GridView1" runat="server">
<columns>
<asp:templatefield>
<itemtemplate>
<asp:checkbox id="Admin" runat="server">

<asp:button id="Button1" runat="server" onclick="Button1_Click" text="Button">

I hope u know it.

Thanks,
Nagraj

Reorder gridview's columns

I try to reorder column of a gridview by overriding CreateColumns. The problem is after i reorder the column, the result table is not correct. The data that is bound into the result table doesn't arrange as i aspect, only the header is. Here is the example .-

no reorder

H1 H2 H3
D11 D12 D13
D12 D 22 D23

reorder column

H2 H3 H1
D11 D12 D13
D12 D 22 D23

why is it ?

Assuming the GridView control have more than 2 fields, the sample code below changes the order of the first two colomns:

protected override ICollection CreateColumns(PagedDataSource dataSource, bool useDataSource)
{
    ICollection collection = base.CreateColumns(dataSource, useDataSource);
	      
    DataControlField[] array = new DataControlField[collection.Count];
    collection.CopyTo(array, 0);
    DataControlField tempField = array[0];
    array[0] = array[1];
    array[1] = tempField;
               
    return array;
}

Nope, this would not work at all; at least for my code. As I said on my question, i can reorder all the columns as expect, and i check that the ICollection that return from the CreateColumns is correct. But however, the data that is bound to the table is not correct.

Actually, i already have the solution. I would post here if someone interest.

Not sure what you do with your custom control, but it does work in my case when I simply declare 3 fields in the exGridView control and use a sqldatasource to feed data. Anyway, glad you solved your problem.

Oh yeah, this might be the cause. I use ObjectDataSource. And i think the GridView do a early bound and cache it something like [ColumnIndex, Value]. Therefore, even if i reorder all columns, but when doing a actual binding The grdiview doesn't use the datafield in each column to retrieve the data, but use the cache data and the column index.

Datagrid Paginng....

Prabs frm PGP17-Aug-06 20:23

Prabs frm PGP

17-Aug-06 20:23

Hi!

I hv the datagrid name as dg. i want to do paginng in that dg control.

I am using c#.

I fetched the imagebutton control name as img to the dg.

If we clicks that img it has to go another form(Models.aspx).

For this i used:

dg_itemdatabound event for find the control (img)

dg_itemcommand event for redirects to next page(Models.aspx)

Now i used 3rd event for the same dg control:

dg_Pageindexchanged event for paging.

Problem is:

I got the Prev & Next Buttons in the dg but if i clicks that one it redirects the page to Models.aspx (which is i mentioned in the itemcommand event)

instead of that it has to display the remaining values...

I hope u got my problem.., How can we solve this one?

Hi,
Please specify what problems you are facing ? By the way you have to start query string with a '?' marks and between two parameters you have to put a '&'. Also there is no need to put the param values in single or double quotes !
If you can specify some details, it would be easier for all here to understand actuall situation !

Hi,
If it is a Web Application then i dont think that it is possible in pure ASP.NET. You will have to use java script for that.

It's simple, the method is used to add the headers to the Response object which is later sent back to the client. I think the topic you may want to learn more is the header part of a Http message, check out this rfc[^]
