Cell Editing Events

[Nikk grey]

Hi,
I have a gridview with rows added at runtime. i have some 5 radcheckbox columns. I wish to detect changes made to checkbox columns. i.e checked state.
I am trying to use the cell_beginedit and cell_endedit events.
I am using 2010 Q1

Problems:
Begin event fires perfectly on first checkbox checked state change. After the event finishes the end event must fire. It only fires whence i change checked box state in another row. else on the same row same checked box cell it wont fire. If i change state of a checkbox cell continuosuly , the beginedit event only fires the first time, next time it doesn't fires because the editor hasn't ended. 

I tried to close the editor myself in the begin edit event but nothing happens.

void gvLiveCnns_CellBeginEdit(object sender, GridViewCellCancelEventArgs e)
{
    // Do some work, cancel event if work not performed as expected
    this.gvLiveCnns.EndEdit();
    this.gvLiveCnns.ActiveEditor.EndEdit();
    this.gvLiveCnns.CloseEditor();
}

Any solution to this problem. Please provide a solution using this event only as i wish to cancel out editing event if worked not performed as expected.

Thank you.

Hello Nikk grey,

Unlike other editors the checkbox editor is a permanent editor and it behaves differently. You should use the ValueChanged event to track when some checkbox changed its value in RadGridView. Here is a sample:

void radGridView1_ValueChanged(object sender, EventArgs e)
{
    RadCheckBoxEditor editor = (RadCheckBoxEditor)sender;
    //...
}

Please describe your scenario in more detail in order to be able to give a more precise suggestion.

Hi,
Thank you for your reply. But i want some further clarification.

As i said before i have a radgridview with multiple checkbox columns. I need to detect checkstate in each cell, i.e i must know the specific cell the checked state occurred. I am attaching a picture for further clarification. 

In the picture attached i have that gridview, e.g. i wish to detect the loaded check state changed by user for each record. I must know the row and cell of the checkbox whose state is changed and the new checked state value too.

Kindly please answer with respect to this scenario. 
Thank you.

Hi Nikk grey,

You can do this by using the CurrentCell property of RadGridView. Please consider the code snippet below:

void radGridView1_ValueChanged(object sender, EventArgs e)
{
    RadCheckBoxEditor editor = sender as RadCheckBoxEditor;
    if (editor != null)
    {
        MessageBox.Show(this.radGridView1.CurrentRow.Cells["ID"].Value.ToString() + " " + this.radGridView1.CurrentColumn.Name);
    }
}

I hope it helps.

Kind regards,
