FindControl inside RadGrid FormTemplateEditForm

[Catalina]

If i use RadGrid in this way (http://demos.telerik.com/aspnet-ajax/grid/examples/dataediting/templateformupdate/defaultcs.aspx), and if inside that FormTemplateEditForm i have another RadGrid, how can i "find" it? If I use (RadGrid)this.Master.FindControl("RadGrid2") i get a null value.

How cand i acces some controls in TemplateEditForm? How can i "find" them?

Hi Catalina,

Try the following code to access controls inside FormTemplate.
C#:

protected void RadGrid1_ItemDataBound(object sender, Telerik.Web.UI.GridItemEventArgs e)
{
 if (e.Item.IsInEditMode && e.Item is GridEditFormItem)
 {
   GridEditFormItem editForm = (GridEditFormItem)e.Item;
   RadGrid grid = (RadGrid)editForm.FindControl("RadGrid2");
 }
}

Thanks,
Shinu.

Yes, this works. But, for example, if in "RadGrid1_UpdateComand", i want to acces some controls inside FormTemplate (my RadGrid2 or anything ele) how can i do that?

Hello catalina,

protected void RadGrid1_UpdateCommand(object sender, GridCommandEventArgs e)
    {
        GridEditFormItem editForm = (GridEditFormItem)e.Item;
        RadGrid grid = (RadGrid)editForm.FindControl("RadGrid2");
    }

Hello,

Please try with the below code snippet.

 

<telerik:RadGrid ID="RadGrid1" runat="server" AutoGenerateColumns="false"
    OnNeedDataSource="RadGrid1_NeedDataSource" OnItemDataBound="RadGrid1_ItemDataBound">
    <MasterTableView>
        <Columns>
            <telerik:GridBoundColumn DataField="Name" HeaderText="Name" UniqueName="Name"></telerik:GridBoundColumn>
            <telerik:GridEditCommandColumn></telerik:GridEditCommandColumn>
        </Columns>
        <EditFormSettings EditFormType="Template">
            <FormTemplate>
                <asp:TextBox ID="txtID" runat="server" Text='<%# Eval("ID") %>'></asp:TextBox>
                <asp:TextBox ID="txtName" runat="server"></asp:TextBox>
            </FormTemplate>
        </EditFormSettings>
    </MasterTableView>
</telerik:RadGrid>

protected void RadGrid1_NeedDataSource(object sender, GridNeedDataSourceEventArgs e)
{
    dynamic data = new[] {
        new { ID = 1, Name ="Name1"},
        new { ID = 2, Name ="Name2"}
    };
    RadGrid1.DataSource = data;
}

protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
{
    if (e.Item.IsInEditMode && e.Item is GridEditFormItem)
    {
        GridEditFormItem editForm = (GridEditFormItem)e.Item;
        TextBox txtName = (TextBox)editForm.FindControl("txtName");
        txtName.Text = "jayesh";
    }
}

Let me know if any concern.
