I use grid3.6 in my winform client.
I add a button cell to the grid.When I click the button,the client will show another form to edit the selected row’s value.When I close the edition form,I need to refresh the grid to show the changes.But when i refresh the grid,a exception will happen and tell me “An attempt was made to select a row that does not belong to the grid”
Here is the message:
??? System.InvalidOperationException

You need to get the value of your second form through the first one and not the opposite.

For example, in Form1, you have a grid with some value. With a button press, you start the Form2 in which you edit the value in a TextBox (in this example “TextBox1”). You close you Form2 by setting DialogResult to OK. After, you can get the result in “TextBox1”.

Here is the code I used for this example:

<code>
//Form1
private void button1_Click( object sender, EventArgs e )
{
Form2 form2 = new Form2();
if( form2.ShowDialog() == DialogResult.OK )
{
gridControl1.DataRows[ 0 ].Cells[ 0 ].Value = form2.Controls[“TextBox1”].Text;
}
}

//Form2
private void button1_Click( object sender, EventArgs e )
{
this.DialogResult = DialogResult.OK;
}
</code>
