Hi jeff torririt,

Thank you for feedback. Unfortunately, the event does not exist in current version of RadGridView. We are trying to cover all events that are in Microsoft DataGridView. We will address this event in some of the next versions.

If you have further questions, feel free to ask us.

Kind regards,

Hello Soalris,

Thank you for writing.

There is an event which you can use to capture cell clicks - CellClick. To make sure that you clicked a data cell, you just need to add a check for this:
void radGridView1_CellClick(object sender, GridViewCellEventArgs e)
{
    GridDataCellElement dataCell = sender as GridDataCellElement;
 
    if (dataCell != null)
    {
          //data cell is clicked
    }
}

I hope this helps.

Svett

Hello Svett, thank you for your reply!

Sorry,but I know about that event and in my situation it is not effective.

To clarify what I want to do, consider such situation:

I have a grid with GridViewCheckBox column. If I use the CellClick() event, then it will also fire even if user is not clicked directly on checkbox,it will fire whenever user clicks on column cell but not on checkbox directly, so that's why I need CellContentClick.

Thanks in advance.
Soalris.

Hello Soalris,

You can achieve the illustrated scenario by using the CellClick event in the following manner:
private void radGridView1_CellClick(object sender, Telerik.WinControls.UI.GridViewCellEventArgs e)
{
    GridCheckBoxCellElement checkBoxCellElement = sender as GridCheckBoxCellElement;
 
    if (checkBoxCellElement != null)
    {
        RadCheckBoxEditorElement element = checkBoxCellElement.Children[0] as RadCheckBoxEditorElement;
        Point mousPos = element.ElementTree.Control.PointToClient(Control.MousePosition);
 
        if (element != null && element.Checkmark.ControlBoundingRectangle.Contains(mousPos))
        {
            //checkbox is clicked
        }
    }
}

I hope this helps.

All the best,
Svett

Hello Svett,

and what if user selects cell and clicks space, which will check checkbox, but Click event will not fire.

So should I implement 2 different handlers for that ?

I think telerik need to consider adding ContentChanged event.

Narek.

Hi Soalris,

In that case, you should use the ValueChanged event which is fired when editor's value is changed. You can read more about editor's events in the online documentation.

Hi Svett, thanks for reply.

When I use ValueChanged() event and check/uncheck checkbox that event simply not firing, until I'll select another cell. But I need to update my form data Immediately, depending on if checkbox checked or not

Any other solution ?

Regards,
Soalris.

Hi Soalris,

I am not able to reproduce the issue. The ValueChanged event occurs when the editor's value is changed. Notice that the value is not committed to underlying data source. If you want to commit it, immediately you should invoke the EndEdit method of RadGridView inside the event handler. If the proposed solution does not resolve your case, I recommend opening support ticket where you can enclose a sample project where the issue occurs.

Dear Svett, thank you very much!

You was right, mistakenly I was using CellValueChanged() event, which was not firing whn I was changing checkbox value.
ValueChanged() is what I need, but now another question - how can I know which row,column changed ?

Regards,
Soalris.

Hello Soalris,

The ValueChanged event fires when RadGridView is in edit mode. And the editor is applied only to the current cell. So, you can use one of the following grid properties to identify the cell: CurrentCell, CurrentRow, CurrentColumn.

I hope this helps.

Hi ValueChanged() is not functioning properly.

Add RadGridView to your project with one checkbox column.
Add this handler, which in my understanding must show the changed value of grid's current cell.

Private Sub RadGridView1_ValueChanged(sender As System.Object, e As System.EventArgs) Handles RadGridView1.ValueChanged
        MsgBox(RadGridView1.CurrentCell.Value)
End Sub

But it is showing always same value, try to change same cell value couple of times without moving cursor into different cell, it will show only 1 value.

What I need to do is this - I need to update immediately checked rows count.

Hi Soalris,

The checkbox editor behaves different compared to other editors in RadGridView. It is a permanent editor and it commits its value to the data layer when the current position in RadGridView (row or cell) changes. That is why the cell value is always the same. You can change this by calling the EndEdit method explicitly:
Private Sub RadGridView1_ValueChanged(sender As System.Object, e As System.EventArgs) Handles RadGridView1.ValueChanged
        Me.RadGridView1.EndEdit()
        MsgBox(RadGridView1.CurrentCell.Value)
End Sub

Please note that ValueChanged event fires when an editor changes its value. You should handle the CellValueChanged event to track changes in cell values caused by an edit operation.

Hi Кeerthi,

Thank you for writing back.

You can achieve the desired result by handling the MouseDown event in the grid and toggling the boolean value of your column for the row on which the click has occurred. Please check the following code snippet: 
public partial class Form1 : Form
{
    public Form1()
    {
        InitializeComponent();
 
        DataTable dt = new DataTable();
        dt.Columns.Add("Id", typeof(int));
        dt.Columns.Add("Name", typeof(string));
        dt.Columns.Add("Date", typeof(DateTime));
        dt.Columns.Add("Bool", typeof(bool));
        for (int i = 0; i < 500; i++)
        {
           dt.Rows.Add(i, "Name" + i, DateTime.Now.AddDays(i), i % 2 == 0);
        }
 
 
        this.radGridView1.DataSource = dt;
        this.radGridView1.AutoSizeColumnsMode = Telerik.WinControls.UI.GridViewAutoSizeColumnsMode.Fill;
 
        this.radGridView1.MouseDown += radGridView1_MouseDown;
    }
 
    private void radGridView1_MouseDown(object sender, MouseEventArgs e)
    {
        if (this.radGridView1.IsInEditMode)
        {
            return;
        }
 
        RadGridView grid = (RadGridView)sender;
        RadElement element = grid.ElementTree.GetElementAtPoint(e.Location);
        if (element is RadCheckmark)
        {
            return;
        }
 
        GridDataCellElement dataCell = element as GridDataCellElement;
        if (dataCell == null)
        {
            RadElement parent = element.Parent;
            while (parent != null)
            {
                if (parent is GridDataCellElement)
                {
                    dataCell =  (GridDataCellElement)parent;
                    break;
                }
 
                parent = parent.Parent;
            }
        }
 
        if (dataCell != null)
        {
            dataCell.RowElement.RowInfo.Cells["Bool"].Value = !(bool)dataCell.RowElement.RowInfo.Cells["Bool"].Value;
        }
    }
}

I am also sending you a short video showing the result on my end.

I hope this helps. Should you have further questions please do not hesitate to write back.

Hristo

Hello Darwin,

Please have in mind that we try to use English in the forums. This way your question will reach more people part of the community.

Instead of creating the CellContentClick event as in the standard grid, we have exposed a CellClick event which will basically provide the same information. You can check one of the previous posts explaining how it can be handled.
