ComboBox in DatagridView in Edit Mode?

See the implementation at ComboBox with read only behavior.

See the implementation at ComboBox with read only behavior. You could also change the DisplayStyle based on when the readonly of the DataGridView property is changed. Setting the DisplayStyle to DataGridViewComboBoxDisplayStyle.

Nothing will hide the drop down button. For example, changing the ReadOnly property with a button click would look something like this: private void mChangeReadOnlyButton_Click(object sender, EventArgs e) { ComboBoxColumn2. DisplayStyle = (dataGridView1.

ReadOnly)? DataGridViewComboBoxDisplayStyle. ComboBox : DataGridViewComboBoxDisplayStyle.

Nothing; dataGridView1. ReadOnly =! DataGridView1.

ReadOnly; } Editable: ReadOnly.

I got my solution actually, but really sorry, I deleted it by mistake. And I undeleted it now. Sorry for trouble.

But in my solution I am facing problem, when my rowindex and columnindex are same. Your solution works fine for me. Thanks.

I got the solution to my problem, just thought to post it here. On entering edit mode, running the following code may solve the problem. Public void bgCombo(DataGridView dg) { foreach (DataGridViewRow row in dg.

Rows) { DataGridViewComboBoxCell dgc = new DataGridViewComboBoxCell(); dgc. Value = row. Cells"Department".

Value; row. Cells"Department" = dgc; } } Before setting dgc to dataGridCell we can add items collections in it. Hope it helps.

PROBLEM: If the Column and Row index, becomes same while editing, I am getting an error - Operation is not valid because it results in a reentrant call to the SetCurrentCellAddressCore function.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
