Hello Santaji,

You can access controls in the FormTemplate as GridEditFormItem, as shown in the code snippet below.

ASPX:

<EditFormSettings>
               <FormTemplate>
                    <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
                    <asp:Button ID="Button3" CommandName="Update" runat="server" Text="Update"/>
               </FormTemplate>
</EditFormSettings>

CS:

  protected void RadGrid1_UpdateCommand(object source, GridCommandEventArgs e)
    {
        if (e.Item is GridEditFormItem)
        {
            GridEditFormItem item = (GridEditFormItem)e.Item;
            TextBox txtbx = (TextBox)item.FindControl("TextBox1");

        }
    }

Thanks
Princy.

but i am adding the controls dynamically in RadGrid1_ItemDataBound
event and then binding them to datasource in Pre render event
So i am not able to access them as mentioned by u .

protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
    {
        if ((e.Item is GridEditableItem) && (e.Item.IsInEditMode))
        {
            GridEditableItem geditem = (GridEditableItem)e.Item;
            geditem["CategoryId"].Controls.Clear();
            geditem["ShortName"].Controls.Clear();
            DropDownList DD = new DropDownList();
            CheckBoxList CL = new CheckBoxList();
            CL.ID = "CL";
            DD.ID = "DD";
            geditem["CategoryId"].Controls.Add(DD);
            geditem["ShortName"].Controls.Add(CL);
        }
    }
    protected void RadGrid1_UpdateCommand(object source, GridCommandEventArgs e)
    {
        if (e.Item is GridEditFormItem)
        {
            GridEditFormItem item = (GridEditFormItem)e.Item;
            DropDownList txtbx = (DropDownList)item.FindControl("DD");
            TextBox txtbxq = (TextBox)item.FindControl("TextBox1");

        }
    }
    protected void RadGrid1_PreRender(object sender, EventArgs e)
    {
        foreach (GridEditFormItem item in RadGrid1.MasterTableView.GetItems(GridItemType.EditFormItem))
        {
            if (item.IsInEditMode)
            {
                DropDownList DDL = (DropDownList)item["CategoryID"].FindControl("DD");
                CheckBoxList CBL = (CheckBoxList)item["ShortName"].FindControl("CL");
                CBL.DataSource = AvailableRecordStatusList.GetStatusList();
                CBL.DataTextField = "value";
                CBL.DataValueField = "key";
                CBL.DataBind();
                DDL.DataSource = AvailableRecordStatusList.GetStatusList();
                DDL.DataTextField = "value";
                DDL.DataValueField = "key";
                DDL.DataBind();
            }
        }

Hi,

Try adding the control in the edit mode in the ItemCreated event and try binding the newly added control in the ItemDataBound event.

CS:

protected void RadGrid1_ItemCreated(object sender, GridItemEventArgs e)
    {
        if ((e.Item is GridEditableItem) && (e.Item.IsInEditMode))
        {
            GridEditableItem edititem = (GridEditableItem)e.Item;
            edititem["Project_Name"].Controls.Clear();
            DropDownList ddl = new DropDownList();

            ddl.ID = "DropDownList1";
            edititem["Project_Name"].Controls.Add(ddl);
          }
      }

 protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
    {
        if ((e.Item is GridEditableItem) && (e.Item.IsInEditMode))
        {
            GridEditableItem editItem = (GridEditableItem)e.Item;
            DropDownList ddl = (DropDownList)editItem["Project_Name"].Controls[0];
            // Bind the DropDown here
        }

    }

Thanks
Shinu.
