[CLOSED] select grid rows with ajax handler

[hillscottc]

In the code at https://examples1.ext.net/#/GridPane...box_Selection/

It demonstrates SELECTING rows in page load like this.....

protected void Page_Load(object sender, EventArgs e)
 {
     if (!Ext.IsAjaxRequest)
     {
         if (!this.IsPostBack)
         {
             RowSelectionModel sm = this.GridPanel1.SelectionModel.Primary as RowSelectionModel;
             // SELECT A COUPLE OF ROWS 
             sm.SelectedRows.Add(new SelectedRow(2));
             sm.SelectedRows.Add(new SelectedRow(4));
         }
     }
}

But I can't make this SELECTION work in an ajax handler method. (No error, just no selection.)

protected void Button2_Click(object sender, AjaxEventArgs e)
{
    RowSelectionModel sm = this.GridPanel1.SelectionModel.Primary as RowSelectionModel;
    
    // .... BUT THIS DOESNT WORK FOR MANUALLY MAKING A SELECTION....
    sm.SelectedRows.Add(new SelectedRow(1));
    sm.SelectedRows.Add(new SelectedRow(5));
}

Any suggestions how I can make this work?

Thanks, in advance.

....I have the Page Load record selecting as demo'ed in the Coolite Example working properly. So I'm confident the grid itself is working as it should.

Hi,

You have to call 'UpdateSelection' method of selection model during ajax event (call it after modifing SelectedRows collection)

PERFECT! Thanks.
