event when Click here to add a new row

[John]

is there an event on a rad grid when the user clicks the "click here to add a new row"?  i can't find one.  I need to have that row visible and clickable, but i don't want it to really add one in the grid.  I want to do a pop up window to add the row and then when that window gets done, i'll manually add it to the dataset behind the grid.  i had another post where someone answered my question with doing custom user controls in the grid to edit data.  that worked great for most of my stuff, but now i have a situation where there are 3 columns in the grid, but the edit form needs to show about 60, so i want to do a popup winform and add a new one that way.  The rest of the grid will be non editable so it's just new rows.

Thanks!

Hi John,

I don't know if it's possible to do what you're asking with the RadGrid, but as an alternative could you put an 'Add New' button somewhere else on the form? That might be easier to implement and still give you exactly the functionality you describe.

yeah, i wish i could do that, it'd be easy, but they don't want to do it.  that's what they had in their old app and want to move to a grid only solution.  i could make a context menu and have my own right click, but it'd look better if i could catch the click on the add new row that was there and do what it wanted.

Understood. 

I haven't tested this out, but there's a March 17, 2011 post by Richard Slade in this thread that might assist:

Good luck!

Hi guys,

Thank you for writing.

If I understand correctly, you need to capture the click of the new row and prevent adding rows with it. If so, here is how you can do that:

void radGridView1_CellClick(object sender, GridViewCellEventArgs e)
{
    GridCellElement clickedCell = (GridCellElement)sender;

    if (clickedCell.RowElement is GridNewRowElement)
    {
        RadMessageBox.Show("New row is clicked");
    }
}

void radGridView1_CellBeginEdit(object sender, GridViewCellCancelEventArgs e)
{
    if (e.Row is GridViewNewRowInfo)
    {
        e.Cancel = true;
    }
}

I hope that you find this information useful.

Hi Stefan,

This works well for launching a dialog, which I use to add an item to the underlying DB. Then I update the datasource to include the added item (code below). After this the top row appears as empty (see screenshot). How can I get it to display "Click here to add new row" text again?

private void grdCompanies_CellClick(object sender, GridViewCellEventArgs e)
{
    var clickedCell = (GridCellElement)sender;

    if (clickedCell.RowElement is GridNewRowElement)
    {
        // https://www.telerik.com/forums/event-when-click-here-to-add-a-new-row

        using (var companyForm = new CompanyForm())
        {
            companyForm.ShowDialog();

            grdCompanies.DataSource = null;
            grdCompanies.DataSource = DashboardDal.ListCompanies();
        }
    }
}

 

 

Cheers,

Chris.

P.S. Sorry for dragging up an old post!

Hello John,

You need to set the current row to null or another row:

radGridView1.CurrentRow = null;

I hope this will be useful.
