Datarepeatercontrol leave event object sender changing!

[drex]

Hello,

my 1st post

I am using visual basic power pack controls and Net 3.5 with the Datarepeatercontrol in c#.

i have it working great!! except for this weird thing i cant figure it out...

i was able to Try and catch the exception and it goes on working unnoticed (and even passes the data????) but i want to fix the exception instead of hiding it.

I have the datarepeater control with a tableLayoutPanel then a textbox on that.

in the textbox textbox_leave event i have the following code:

private void txtdata_Leave(object sender, EventArgs e)
        {
            try
            {
                dtsource.Rows[CurrentRow][intColIndex] = ((TextBox)sender).Text;
                ((DataTable)rptrData.DataSource).Rows[intColIndex]["ColumnData"] = ((TextBox)sender).Text;

              
            }
            catch
            {

                ;
            }

so basically it updates my datatable when i leave the textbox.

if i leave the texbox to anything on the repeater data control, it doesnt show an error

but if i go to click something outside of the window, like a menu item or button outside of the data repeater control area i get a

"Unable to cast object blah blah visual basic powerpack to System.textbox"


so i click continue and it still works!! the data is still updated into the table...

so for a quick fix i put in the try and catch and it works.

but i want to fix it right...


it looks like it sending 2 different objects as the sender?? hmmmm i dunno how to fix it.

please help !!

thanks
