Change Grid Editors Button's Caption

[niloofar]

hi
I've got an radgrid with edit/delete/insert features enabled on. editmode for the grid is set to popup. I'd like to know How can I alter edit window's Update/Cancel buttons captions' to some other langueage ( destination language is Persian(Iran)) . Perferebly I would enjoy setting some properties to write my own stuff.

thanks for upcomming replies.
With Kind Regards

Hello,


Set the properties following properties to changing the Update/Insert/Cancel text in edit/insert form.

Code:

protected void RadGrid1_PreRender(object sender, EventArgs e)
{
    RadGrid1.MasterTableView.EditFormSettings.EditColumn.UpdateText = "Change";
    RadGrid1.MasterTableView.EditFormSettings.EditColumn.CancelText = "Close";
    RadGrid1.MasterTableView.EditFormSettings.EditColumn.InsertText = "Add";
}

This example is good but when we are getting an exception (during insert/update to db):

void Grid_InsertCommand(object source, GridCommandEventArgs e)
        {
            try
            {
                // Save to db
            }
            catch (Exception ex)
            {
                e.Canceled = true;
            }
        }

 those captions are setting back to previous values. How to avoid that?

Hello wnl,

What is the exception you are getting. Can you remove the try-catch block, get the exception message and stack trace and post it here (can be an image too).

The exception is simply: I leave empty field with primary key and try to save and of course - exception from db.
Without try/catch block the pop-up with edit has correct value of labels.

From trace:

OK, so you are catching a possible exception an invalid DB operation may throw and the button text is reverting to its original value after an exception is caught. Have you tried declaratively setting the button text:

<telerik:RadGrid>
    <MasterTableView>
        <EditFormSettings>
            <EditColumn UpdateText="Dodaj" CancelText="Anuluj" />
        </EditFormSettings>
    </MasterTableView>
</telerik:RadGrid>

If this does not help, you can programmatically find these buttons in the grid edit items and change their text:

protected void Page_PreRender(object sender, EventArgs e)
{
    var editForms = RadGrid1.MasterTableView.GetItems(GridItemType.EditFormItem);
    foreach (var item in editForms)
    {
        //find update button in edit forms
        LinkButton updateButton = item.FindControl("UpdateButton") as LinkButton;
        if (updateButton != null)
        {
            updateButton.Text = "Dodaj";
        }

        //find insert button in insert form
        LinkButton insertButton = item.FindControl("PerformInsertButton") as LinkButton;
        if(insertButton != null)
        {
            insertButton.Text = "Insert text here";
        }

        LinkButton cancelButton = (LinkButton)item.FindControl("CancelButton");
        cancelButton.Text = "Anuluj";
    }
}
