    Hello

    I have a gridview in which I have added a GridViewCheckBoxColumn

    I have not found which event is fired when I click on the check box and how to get the value of the checkbos (checked or not) without leaving the cell.

    In other word how can I catch the click on the check bos and test its value.
    the CellValueChanged event is fired only when I leave the cell ...
    the CellClick Event allows me to get the cell but not the checkbox value ..

    Any idea ?

    Thanks in advance

    Have you tried handling the ValueChanged event?

    private void radGridView1_ValueChanged(object sender, EventArgs e)
    {
        string msg = "";
        try
        {
            if (radGridView1.ActiveEditor is RadCheckBoxEditor && radGridView1.CurrentCell.RowIndex >= 0)
            {
                 
                    if (checkState == "On")
                    {
                        // do something
                    }
                    else if (checkState == "Off")
                    {
                        // do something
                    }
            }
        }
        catch (Exception ex)
        {
            msg = ex.Message.ToString();

    I forgot to add where the value checkState comes from.

    private void radGridView1_ValueChanged(object sender, EventArgs e)
    {
        string msg = "";
        try
        {
            if (radGridView1.ActiveEditor is RadCheckBoxEditor && radGridView1.CurrentCell.RowIndex >= 0)
            {
                string checkState = rgvReportList.ActiveEditor.Value.ToString();
                    if (checkState == "On")
                    {
                        // do something
                    }
                    else if (checkState == "Off")
                    {
                        // do something
                    }
            }
        }
        catch (Exception ex)
        {
            msg = ex.Message.ToString();
        }
    }

    Hello thanks for your information

    Yes I have tried the valuechanged event, but is is fired when I "leave" the cell that contains the CheckBox, I would like an event that is fired when I click the checkbox, without leaving the cell and a property that tells me if the checkbox is checked or not.

    OK thanks to your input I found the solution:

    1. I Declare a checkEditor
        Private WithEvents Checkeditor As RadCheckBoxEditor

    2. In the CellEditorInitialized event I instanciate the checkbox

        If TypeOf e.ActiveEditor Is RadCheckBoxEditor Then
                Checkeditor = e.ActiveEditor
         End If

    3. The CheckEditor has an event ValueChanged that is fired a every click in the check box and
    the checkeditor.value property is "off" or "on", combined with the grid currentrow I have all I need

     

    Thanks for your suggestions that have sent me in the right direction

    Best Regards

    Hello, guys,
     
    I am glad that you have discussed the scenario with clicking a cell inside a GridViewCheckBoxColumn. 

    However, please have in mind that the GridViewCheckBoxColumn offers the EditMode property. This property determines whether changing a value of a check box will immediately be send to the cell (OnValueChange) or when the current cell is changed or the grid is being validated (OnCellChangeOrValidating). Feel free to set the EditMode property to OnValueChange and handle the CellValueChanged event. In this case, the event will be fired as soon as you click a checkbox.

    I hope this information helps. If you need any further assistance please don't hesitate to contact me.

    Hello Dess

    Thanks for this complement of information, it clearly is a more straight forward mechanism to handle the Click Event on the checkBox.

    I will modify my code to handle the click event as you suggest

    Best Regards

    Pierre-Jean
