Clear fields in grid item on item command

[Alin]

Hello

I have a grid with a template column like this

<telerik:GridTemplateColumn HeaderText="Program Id" AllowFiltering="true" Reorderable="true" SortExpression="Program_Id"
                    UniqueName="Program_Id" DataField="Program_Id">
                        <ItemTemplate>
                            <asp:Label ID="lblProgrammeId" runat="server" Text='<%# Eval("Program_Id") %>' />
                        </ItemTemplate>
                        <EditItemTemplate>
                            <telerik:RadTextBox ID="txbProgrammeId" Width="50px" runat="server" TextMode="SingleLine"
                                Text='<%# Bind("Program_Id") %>' />
                            <telerik:RadButton ID="ValidateProgBtn" AutoPostBack="true" runat="server" Width="16px"
                                Height="16px" CommandName="ValidateProgId" ToolTip="Validate the programme id" Text="Cancel">
                                <Image ImageUrl="Images/1305817624_clean.png" />
                            </telerik:RadButton>
                             <%--OnClientClicked="ClearFields" OnClientClicking="OnClientButtonClickingHandler"--%>
                            <telerik:RadButton ID="RadButton1" AutoPostBack="true" Value="NoPostBack" runat="server" Width="16px"
                                Height="16px" CommandName="Clear All"
                                ToolTip="Clear the fields" Text="Clear">
                                <Image ImageUrl="Images/1305817654_edit-clear.png" />
                            </telerik:RadButton>
                            <asp:Label ID="IsNewProgLbl" runat="server" style="width:auto; color:Orange" Text=""></asp:Label>
                        </EditItemTemplate>
                        <ItemStyle VerticalAlign="Top" />
                 </telerik:GridTemplateColumn>

When I click the clear all button, in edit mode, I want the fields from the grid to be cleared and also set the readonly property to false( it is set to true in a previous state). So I set the command name, then catch it in RadGrid1_ItemCommand event handler and try to access  a field like this:

......
if (e.CommandName == "Clear All")
            {

                    (e.Item.FindControl("txbProgrammeId") as RadTextBox).Text = "";
                    (e.Item.FindControl("txbProgrammeId") as RadTextBox).ReadOnly = false;
...........

But it seems that only the Label control exists! I can't find the RadTextBox or RadButton controls. I find this strange, since when the grid is in insert mode it works ok. I even tried to force the grid to be in edit mode

e.Item.Edit = true;
GridEditableItem editedItem = e.Item as GridEditableItem;

but still nothing.
Is there a way that I can use to solve this? Basically, I want a  button that clears some fields when the grid is in edit or insert mode.

Thx a lot.

Hello Alin,

 Since the RadTextBox is in EditItemTemplate, you need to access the GridEditableItem(EditMode=InPlace) first. For that you can use the  "e.CommandSource" for getting the RadButton and then access the GridEdittableItem by using the RadButton's NamingContainer property. Here is the sample code that I tried. Hope this helps you.

C#:

protected void RadGrid1_ItemCommand(object sender, GridCommandEventArgs e)
{

  if (e.CommandName == "ClearAll")

    {

    GridEditableItem item = (GridEditableItem)((e.CommandSource) as RadButton).NamingContainer;

    RadTextBox txtBox = (RadTextBox)item.FindControl("txbProgrammeId");

       txtBox.Text = "";

       txtBox.ReadOnly = false;

      }

}

Thanks,
Princy.
