Hello,
I am extremely new to asp.net and especially new to telerik. I am trying to create a gridview with the following code, just to see how it works, but i ran into a wierd problem, i added the commanditemdisplay to top, and it adds the "add button" every time i click it for some reason it adds the edit and delete buttons multipe times per row, not sure what i am doing wrong in order to cause that, but can someone please help me with this.

public partial class Default4 : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
        if (Session["GridData"] == null)
        {
            DataTable table = GetTable();
            Session.Add("GridData", table);
        }
        DefineGridStructure();
    }

    private void DefineGridStructure()
    {

        DataTable current = (DataTable)Session["GridData"];

        RadGrid grid = new RadGrid();
        grid.ID = "RadGrid1";
        grid.DataSource = current;
        grid.AutoGenerateEditColumn = true;
        grid.AutoGenerateDeleteColumn = true;
        grid.AllowAutomaticInserts = true;
        grid.Width = Unit.Percentage(100);
        grid.PageSize = 15;
        grid.AllowPaging = true;
        grid.PagerStyle.Mode = GridPagerMode.NextPrevAndNumeric;

        grid.MasterTableView.Columns.Add(boundColumn);
        grid.DataBind();
        PlaceHolder1.Controls.Add(grid);
    }

    static DataTable GetTable()

        //

Hi,

Please try the following code snippet, I have removed the 'grid.DataBind()' from your code and bound the RadGrid in NeedDataSource event.

C#:

protected void Page_Load(object sender, EventArgs e)

{

if (Session["GridData"] == null)

{

DataTable table = GetTable();

Session.Add("GridData", table);

}

DefineGridStructure();

}

private void DefineGridStructure()

{

RadGrid grid = new RadGrid();

grid.ID = "RadGrid1";

grid.NeedDataSource += new GridNeedDataSourceEventHandler(grid_NeedDataSource);

grid.AutoGenerateEditColumn = true;

grid.AutoGenerateDeleteColumn = true;

grid.AllowAutomaticInserts = true;

grid.Width = Unit.Percentage(100);

grid.PageSize = 15;

grid.AllowPaging = true;

grid.PagerStyle.Mode = GridPagerMode.NextPrevAndNumeric;

grid.AutoGenerateColumns = false;

grid.MasterTableView.Width = Unit.Percentage(100);

grid.MasterTableView.CommandItemDisplay = GridCommandItemDisplay.TopAndBottom;

grid.MasterTableView.DataKeyNames = new string[] { "RowNumber" };

GridBoundColumn boundColumn = new GridBoundColumn();

boundColumn.DataField = "RowNumber";

boundColumn.HeaderText = "RowNumber";
