[lupotana]

Good morning,
I've a RadGrid object built in a function and after add this grid in the list of controls of the page.

My problem is the GridGroupHeaderItem that is visible.
I try to set the property grid.GroupingEnabled = false; during the creation but don't work.

How cai I do for hide this column in this scenario ?

RadGrid1.ShowGroupPanel = false;

As per my thought you want to hide GroupPanel Let me know if i am not understand your requirement.


Thanks,

Yes, yuou understand right but RadGrid1.ShowGroupPanel not work.
I think that is a problem with the new relase of Telerik becouse the last year the same code work well.

Hello lupotana,

I am afraid we are unable to replicate the issue on our side. Could you please provide us the exact steps to reproduce the problematic behavior locally?

Also, if you are creating your grid programmatically, please verify that you are closely following the tips related to your specific scenario, which are provided in the topic below:

Exscuse me for my English.. I explane my problem whith an example...

I create a simple RadGrid in PageLoad and before I add this control to a panel..

protected void Page_Load(object sender, EventArgs e)
    {
        DataTable dt = new DataTable();
        dt.Columns.Add(new DataColumn("CODE", Type.GetType("System.Int32")));
        dt.Columns.Add(new DataColumn("DESCRIPTION", Type.GetType("System.String")));

        for (int i = 0; i < 10; i++)
        {
            DataRow dr = dt.NewRow();
            dr["CODE"] = i;
            dr["DESCRIPTION"] = string.Format("DESCRIPTION FOR {0} RECORD", i);
            dt.Rows.Add(dr);
        }

        RadGrid grid = new RadGrid();
        grid.DataSource = dt;
        grid.ShowGroupPanel = false;
        grid.DataBind();
        grid.ColumnCreated += new GridColumnCreatedEventHandler(grid_ColumnCreated);
        pnlData.Controls.Add(grid);
    }

    void grid_ColumnCreated(object sender, GridColumnCreatedEventArgs e)
    {
        if (e.Column is GridGroupSplitterColumn)
            e.Column.Visible = false;
    }

In attached  you can see the result in the web form.

My question is : How I hide the GridGroupSplitterColumn ?

In this example I try it in two way :
- Set grid.ShowGroupPanel = false;
- With grid_ColumnCreated event (this way work in RadGrid not generate by code)

Help ?
THhank you :-)

SOLVED !!!

GridExpandColumn AND NOT GridGroupSplitterColumn

void grid_ColumnCreated(object sender, GridColumnCreatedEventArgs e)
    {
        if (e.Column is GridExpandColumn)
            e.Column.Visible = false;
    }
