Problem when focus shifts away from the GDBG

I have a GDBG 1.6.1,6, It is bound to a DataView, most of the columns are bound checkboxes. When user clicks on any checkbox in the first row of the grid, and then clicks on any other control (such as a button) on a form, the first row's checkbox is reset to the original state. This does not happen if user edits any other row, i.e. clicking away does not change state of the row unexpectedly (which is the normal behavior) Gene Gorokhovsky

More info: the problem only occurs when editing the first row is the first action that user does on the grid. After changes to any other row the problem no longer manifests itself. > I have a GDBG 1.6.1,6, It is bound to a DataView, most of the columns are bound checkboxes. > When user clicks on any checkbox in the first row of the grid, and then clicks on any other control (such as a button) on a form, the first row's checkbox is reset to the original state. > This does not happen if user edits any other row, i.e. clicking away does not change state of the row unexpectedly (which is the normal behavior) > > Gene Gorokhovsky

I tried to see this problem in the attached sample using 1.6.1.6, but could not. Can you see the problem in this sample?

The problem can bee seen in the attached sample. I have modified your code with several relevant fragments that we are using in our app. Sorry if the code is not absolutely minimal. Gene

The samething is happening to me in my app(1.6.1.8 databound grid). The first row checkbox is getting reset. After another change is made, it is taking the values properly. Sometimes, non-checkbox (combobox, textbox) values are also getting reset. Thanks, - Reddy

I think you can avoid the problem by setting the datasource after you set the GridBoundColumns instead of before you set them. 
//this.DataSource = dataSource;
if (cols != null) 
{
	this.GridBoundColumns.AddRange(cols);	
}
this.DataSource = dataSource;

It worked.This was a strange one, indeed. Thanks! Gene

Clay, I'm running into the same problem, but only on one form. The grid displays the data of a child relation. Sometimes the text typed into the first cell will be lost after moving to the next row/cell e.g. by pressing the tab key. I want to check if the reset of the DataSource will solve the problem.
