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....

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[^]

Fetching data from gridview to label in another form.

In C#, .NET 2.0. I have a gridview in frm_Report which looks like this.
i have used the sqldatasource to bind the data.

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" DataKeyNames="Stud_Admin" DataSourceID="SqlDataSource1">
<Columns>
<asp:BoundField DataField="Stud_Admin" HeaderText="Stud_Admin" ReadOnly="True" SortExpression="Stud_Admin" />
<asp:BoundField DataField="Stud_Name" HeaderText="Stud_Name" SortExpression="Stud_Name" />
<asp:HyperLinkField HeaderText="" Text="View" DataNavigateUrlFields="Stud_Admin" DataNavigateUrlFormatString="frm_StudReport.aspx />
</Columns>
</asp:GridView>
<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:FYPJ_TestDBConnectionString2 %>"
SelectCommand="SELECT [SN], [Stud_Admin] FROM [Stud_Particulars]">
</asp:SqlDataSource>

In my another form frm_Show is basically this.

<asp:Label ID="Label1" runat="server" Text="Label"></asp:Label>

When user select the hyperlink View, the hyperlink will grab value of Stud_Admin of the selected row in gridview and display it at Label1. What is the next code should I add?

thanks in advance. Much appreciated.

use Row.RowIndex property to get the selected row..
use RowCommand event of GridView.

I don't know what to do next. By getting the values, how will the hyperlink be clever to pass value to label in another form. And what is the syntax for Label1.text = ? By using findcontrol?

And

protected void GridView8_RowCommand(object sender, GridViewCommandEventArgs e)<br />
{<br />
    GridViewRow row = GridView8.Rows[0];<br />
}

thanks in advance. Much appreciated.

If the Stud_Admin text is simple, you may consider passing the value along with the url in the query string (set this DataNavigateUrlFormatString="frm_StudReport.aspx?Stud_Admin={0}" )so that you can get it from the Request object in the next page . In addition, you still have many other choices:
+ Try to retrieve again in DB based on the id passed from the source page when the text is long.
+ Try to use the LinkButton, so before redirecting to the next page you can save the text in the Session.

Thank you. It works.

But I was just wondering what does Stud_Admin={0} means?

If I want to pass two values which is Stud_admin and the next column just next to Stud_Admin? What will the longer DataNavigateUrlFormatString = be?

thanks in advance. Much appreciated.

I still don't understand. Cry | :((

I am using codebehind. And initially i can fetch one data from the gridview to another webform and display it in the label.

I want to experiment and fetch two datas from the gridview to another webform and display it in the label.

<Columns>
<asp:BoundField DataField="Stud_Admin" HeaderText="Admin No" ReadOnly="True" SortExpression="Stud_Admin" />
<asp:BoundField DataField="Stud_Name" HeaderText="Student Name" SortExpression="Stud_Name" />
<asp:HyperLinkField Text="View" DataNavigateUrlFields="Stud_Admin" DataNavigateUrlFormatString="frm_StudReport.aspx?Stud_Admin={0}"/>
</Columns>

And another webform at the page load,

<code>Label1.Text = Request.QueryString["Stud_Admin"];</code>

How can I fetch the Stud_Name as well and display it in Label2.text?

thanks in advance. Much appreciated.

Well, the explanation in MSDN is clear enough:

+DataNavigateUrlFields="Stud_Admin,Stud_Name" (seperated by comma)

+DataNavigateUrlFormatString="frm_StudReport.aspx?Stud_Admin={0}&Stud_Name={0}" (the parameters in the url are seperated by the &)
