Radgrid header

[Rajeswari]

Hi
I have a question regarding radgrid header. I want to make 4 headers  in the grid redirect to a  different page and display as a link. How can i capture the click event of the header as i have to  loop through the radgrid and get the values of that column (header clicked column) to update the table.

Thanks,
Rajeswari Raman

Hello,

Please try with the below code snippet.

protected void RadGrid1_ItemCommand(object sender, GridCommandEventArgs e)
{
    if (e.CommandName == RadGrid.SortCommandName)
    {
        e.Canceled = true;
        Response.Redirect("Default.aspx?HeaderName=" + e.CommandArgument);
    }
}

<telerik:RadGrid ID="RadGrid1" runat="server" OnNeedDataSource="RadGrid1_NeedDataSource"      AllowMultiRowSelection="true" OnItemCommand="RadGrid1_ItemCommand" AllowSorting="true">
    <MasterTableView AutoGenerateColumns="False">
        <Columns>
            <telerik:GridClientSelectColumn></telerik:GridClientSelectColumn>
            <telerik:GridBoundColumn DataField="Id" HeaderText="Id" UniqueName="Id">
            </telerik:GridBoundColumn>
            <telerik:GridBoundColumn DataField="Name" HeaderText="Name" UniqueName="Name">
            </telerik:GridBoundColumn>
            <telerik:GridEditCommandColumn></telerik:GridEditCommandColumn>
        </Columns>
    </MasterTableView>

</telerik:RadGrid>

Let me know if any concern.

Thanks for your reply. That resolved the problem  I want to change the default page size of the radgrid with page size 50 and 100 only .i added the following in  radgrid itemCreated event
Dim myPageSizeCombo As RadComboBox = e.Item.FindControl("PageSizeComboBox")
Dim myItem As RadComboBoxItem
myPageSizeCombo.Items.Clear()
myItem = New RadComboBoxItem("50", "50")
myPageSizeCombo.Items.Add(myItem)
myItem.Attributes.Add("ownerTableViewId", grdgroup.MasterTableView.ClientID)
myItem = New RadComboBoxItem("100", "100")
myPageSizeCombo.Items.Add(myItem)
myItem.Attributes.Add("ownerTableViewId", grdgroup.MasterTableView.ClientID)
  I always get  object reference error  the following code (grdgroup pagsize.tostring showing as 10which is default in debug)     
  myPageSizeCombo.FindItemByText(grdgroup.PageSize.ToString()).Selected = True

Thanks,

Hi,
I want to show pagersize 50, 100 only as default . I dont want based on record count . I always get  null refrence error on the following line  
myPageSizeCombo.FindItemByValue(grdgroup.PageSize.ToString()).Selected = True
I added the following code in item databound function.
  If TypeOf (e.Item) Is GridPagerItem Then

Dim myPageSizeCombo As RadComboBox = e.Item.FindControl("PageSizeComboBox")
Dim myItem As RadComboBoxItem
myPageSizeCombo.Items.Clear()
myPageSizeCombo.AutoPostBack = True
myPageSizeCombo.Items.Add(New RadComboBoxItem("50"))
myPageSizeCombo.FindItemByText("50").Attributes.Add("ownerTableViewId", grdgroup.MasterTableView.ClientID)
'myPageSizeCombo.FindItemByText(grdgroup.PageSize.ToString()).Selected = True
myPageSizeCombo.Items.Add(New RadComboBoxItem("100"))
myPageSizeCombo.FindItemByText("100").Attributes.Add("ownerTableViewId", grdgroup.MasterTableView.ClientID)
myPageSizeCombo.FindItemByValue(grdgroup.PageSize.ToString()).Selected = True
End If
Following is my aspx code
<PagerStyle Mode="NextPrevAndNumeric" BorderStyle="None"
AlwaysVisible="true" PageSizeControlType="RadComboBox" ></PagerStyle>

Hi ,
I modified the code as you posted . Now I am not getting null refrence error. But when the grdloaded first time eventhough there were 65 items it was showing as 0 items in 1 page in the bottom of the grid . The pagesize combo was showing 50,100. When i change  pagesize to 100 in the combo,   it was showing all the page index from 1 to seven and the display was 65 items in 7 pages . it was always defaulting to  default pagesize and page indexes. On the aspx side i have Allowcustompaging set to true .
Thanks
