Command in EditMode/InsertMode

[Dave]

Hello!

I've a RadGrid where the User can manage some data.

In Edit- or Insert-Mode the User should be able to provide some data, the data will be checked against a Webservice and the result should be visible in Edit-Mode so the User can view them and finally Click "Finsh" to save the data and end the Edit-Mode.

My Problem is, that I don't know how to handle the Button-Click, where the data is checked.

In ItemCommand I can handle the Button-Event, but I have no access to the EditForm (as far as I know)

protected void DataRadGridItemCommand(object source, GridCommandEventArgs e)
{
    switch (e.CommandName)
    {
        case "CheckData":
            //Check data
            break;
    }
}

In ItemDataBound I have access to the Edit-Form, butI don't know how to handle the Button-Event.

protected void DataRadGridOnItemDataBound(object sender, GridItemEventArgs e)
{
    if (!(e.Item is GridDataItem)) return;

    if (e.Item.IsInEditMode)
    {
        var item = (GridEditableItem) e.Item;
        // Access the EditForm
    }
}

Any suggestions, hints?

Thanks in advance.

Hello Dieter,

I guess the 'CheckData' button is inside edit form. Then one way to achieve this is by attaching an 'OnClick' event to that 'CheckData' Button. And in the event handler access the edit form using NamingContainer propery of button.

ASPX:

<Columns>
    <telerik:GridBoundColumn DataField="FirstName" UniqueName="FirstName" HeaderText="FirstName">
    </telerik:GridBoundColumn>
     <telerik:GridTemplateColumn>
        <EditItemTemplate>
            <asp:Button ID="Button2" runat="server" Text="CheckData" CommandName="CheckData" OnClick="Button2_Click" />
        </EditItemTemplate>
    </telerik:GridTemplateColumn>
</Columns>

C#:

protected void Button2_Click(object sender, EventArgs e)
   {
       Button chkButton = (Button)sender;
       GridEditFormItem editItem = (GridEditFormItem)chkButton.NamingContainer; // access editform
       TextBox txt = (TextBox)editItem["FirstName"].Controls[0];
       string value = txt.Text;
   }

You can also access the edit form in ItemCommand event like below.

C#:

protected void RadGrid1_ItemCommand(object source, GridCommandEventArgs e)
   {
       switch (e.CommandName)
       {
           case "CheckData":
               {
                   Button chkButton = (Button)e.CommandSource;
                   GridEditFormItem editItem = (GridEditFormItem)chkButton.NamingContainer;
                   TextBox txt = (TextBox)editItem["FirstName"].Controls[0];
                   string value = txt.Text;
               }
       }
   }

Thanks,
Princy.

Hello!

Sorry, but now I'm facing another problem:

protected void DataRadGridItemCommand(object source, GridCommandEventArgs e)
{
    switch (e.CommandName)
    {
        case "CheckData":
            var chkButton = (Button)e.CommandSource;
            var editItem = (GridEditFormItem)chkButton.NamingContainer;

            var tb1 = (TextBox)editItem.FindControl("TextBox1");

            var result = CheckData(tb1.Text);

            var tb2 = (TextBox)editItem.FindControl("TextBox2");
            tb2.Text = result;

            break;
    }
}

The Text of the TextBox2 stays empty, even if I try this

protected void DataRadGridItemCommand(object source, GridCommandEventArgs e)
{
    switch (e.CommandName)
    {
        case "CheckData":
            var chkButton = (Button)e.CommandSource;
            var editItem = (GridEditFormItem)chkButton.NamingContainer;

            var tb2 = (TextBox)editItem.FindControl("TextBox2");
            tb2.Text = "TEST";

           break;
    }
}

Maybe there's a Bind-Action on the Grid afterwards. I tried several ways to avoid this, but without luck.

Thanks for any hint.
