RadGrid with a Redirect

[M]

I'm trying to Display the selected record in a asp.formview on the same page as the RadGrid.
When I click the 'Select' (GridButtonColumn) Button no Redirect occurs.
If I type in the entire Page URL with a QueryString value (http://10.0.0.110/Listing1.aspx?id=781) the formview displays the record.

Here is the code:

<telerik:RadGrid ID="RadGrid1" runat="server" 

                    AllowFilteringByColumn="True" 

                    AllowPaging="True" 

                    AllowSorting="True"

                    DataSourceID="SqlDataSource1" 

                    GridLines="None" 

                    Height="700px" 

                    PageSize="20"> 

                    <ClientSettings AllowColumnsReorder="True"> 

                        <Selecting AllowRowSelect="True" /> 

                        <Scrolling AllowScroll="True" UseStaticHeaders="True" /> 

                    </ClientSettings> 

                    <MasterTableView datasourceid="SqlDataSource1" DataKeyNames="id"> 

                        <Columns> 

                            <telerik:GridButtonColumn CommandName="Redirect" Text="Select" ButtonType="PushButton" UniqueName="ButtonColumn"> 

                                <HeaderStyle Width="70px" /> 

                            </telerik:GridButtonColumn>  

                        </Columns> 

                        <RowIndicatorColumn> 

                            <HeaderStyle Width="20px"></HeaderStyle> 

                        </RowIndicatorColumn> 

                        <ExpandCollapseColumn> 

                            <HeaderStyle Width="20px"></HeaderStyle> 

                        </ExpandCollapseColumn> 

                        <NoRecordsTemplate> 

                            Sorry No Records Found, Modify your search and try again. 

                        </NoRecordsTemplate> 

                    </MasterTableView> 

                    <PagerStyle Position="TopAndBottom" /> 

                </telerik:RadGrid> 


CodeBehind:

protected void RadGrid1_ItemCommand(object source, GridCommandEventArgs e)
    {
        if (e.CommandName == "Redirect")
        {
            GridDataItem item = (GridDataItem)e.Item;
            string value = item.GetDataKeyValue("id").ToString(); // Get the value in clicked row
            // Save the required  value in session
            string url = "listing1.aspx?id=" + value;
            Response.Redirect(url);
        }
    }

Thank you in advance!

Hello Mike,


If the controls are placed in same page, then you can achieve this setting the "SelectParameters" rather than redirecting the page.

Sample code, you can find here.

<telerik:RadGrid ID="RadGrid1" TabIndex="1" AllowFilteringByColumn="true" ShowGroupPanel="True"
    AllowMultiRowSelection="false" ShowStatusBar="true" runat="server" DataSourceID="SqlDataSource1"
    AutoGenerateColumns="false" PageSize="10" AllowSorting="True" AllowPaging="True">
      <MasterTableView HierarchyDefaultExpanded="false" TableLayout="Fixed" AllowMultiColumnSorting="True"
                CommandItemDisplay="Top" DataKeyNames="CustomerID" DataSourceID="SqlDataSource1">
               <Columns>
                    <telerik:GridButtonColumn CommandName="Select" Text="Select">
                    </telerik:GridButtonColumn>
             . . .
            </MasterTableView>
        </telerik:RadGrid>

<asp:SqlDataSource ID="SqlDataSource2" ConnectionString="<%$ ConnectionStrings:NorthwindConnectionString %>"
    ProviderName="System.Data.SqlClient" SelectCommand="SELECT * FROM Customers WHERE CustomerID=@CustomerID"
    runat="server">
    <SelectParameters>
        <asp:ControlParameter ControlID="RadGrid1" PropertyName="SelectedValue" Name="CustomerID" />
    </SelectParameters>
</asp:SqlDataSource>

<asp:FormView ID="FormView1" runat="server" DataSourceID="SqlDataSource2" Height="206px"
    BorderStyle="Solid" BorderColor="Black" Width="347px">
   <ItemTemplate>
     . . .

Something else is missing.
It still isn't displaying the Formview.

Something must be missing.
I don't see it.

Thanks,

Hello Mike,


You need to set the AjaxManager - AjaxSettings in way that RadGrid1 updates FormView1 to get the functionality.


Try the following setting and see whether it helps:

<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">

    <AjaxSettings>

        <telerik:AjaxSetting AjaxControlID="RadGrid1">

            <UpdatedControls>

                <telerik:AjaxUpdatedControl ControlID="RadGrid1" /> 


                <telerik:AjaxUpdatedControl ControlID="FormView1" />

            </UpdatedControls>

        </telerik:AjaxSetting>

        <telerik:AjaxSetting AjaxControlID="SqlDataSource1">

        </telerik:AjaxSetting>

    </AjaxSettings>

</telerik:RadAjaxManager>
