Delete "Group by" option from Header Context Filter Menu

[Aitor]

Hi,

I think the title of this thread is clear enough to know what I really want to get, isn´t it? :-)

I want somehow to access to filter options of header context menu and delete "Group by" and "Ungroup" options from this menu. Is is possible?

Thank you in advance

Hello Aitor,

protected void Page_Load(object sender, EventArgs e)
    {
        RadGrid1.HeaderContextMenu.ItemCreated += this.HeaderContextMenu_ItemCreated;
    }
    private void HeaderContextMenu_ItemCreated(object sender, RadMenuEventArgs e)
    {
        switch ((e.Item.Text))
        {
            case "Group By":
                e.Item.Visible = false;
                //e.Item.Text = "New Text"; you can also change text
                break;
            case "Ungroup":
                e.Item.Visible = false;
                break;
        }
    }

if you get two separator after hiding the group and ungroup option then you can try below solution.

public int count

{

    get

    {

        if (ViewState["Count"] != null)

            return Convert.ToInt32(ViewState["Count"]);

        else

            return 0;

    }

    set

    {

        ViewState["Count"] = value;

    }

}

 

protected void Page_Load(object sender, EventArgs e)

{

    RadGrid1.HeaderContextMenu.ItemCreated += this.HeaderContextMenu_ItemCreated;

}

private void HeaderContextMenu_ItemCreated(object sender, RadMenuEventArgs e)

{

    switch ((e.Item.Text))

    {

        case "Group By":

            e.Item.Visible = false;

            count++;

            //e.Item.Text = "New Text"; you can also change text

            break;

        case "Ungroup":

            e.Item.Visible = false;

            count++;

            break;

        case "":

            if (count == 2)

            {

                e.Item.Visible = false;

                count = 0;

            }

            break;
          Default:
                    count =0;
                             break;

    }

}

let me know if any concern.

Hello Aitor,

Please try using the following code in order to remove the "Group By" and "UnGroup" items.

protected void Page_Load(object o, EventArgs e)

{

    RadGrid1.HeaderContextMenu.ItemCreated += new RadMenuEventHandler(HeaderContextMenu_ItemCreated);

}

  

void HeaderContextMenu_ItemCreated(object sender, RadMenuEventArgs e)

{

    if (e.Item.Text == "Group By")

    {

        e.Item.Style.Add("display", "none");

        (sender as RadContextMenu).Items[e.Item.Index - 1].Remove();

    }
      if (e.Item.Text == "UnGroup")

    {

        e.Item.Style.Add("display", "none");

        (sender as RadContextMenu).Items[e.Item.Index - 1].Remove();

    }

}

Thanks,
Shinu.
