Hide Column Header Only

[Kaka]

Hi,

I want to hide a one header (info header) but not the data like below, is it possible?

===============================
First Name          | Last Name                         --> Header
===============================
First Name 1       | Last Name 1
------------------------------------------------------       --> row 1
Info 1
===============================
First Name 2       | Last Name 2
------------------------------------------------------       --> row 2
Info 2
===============================

Thanks

Hi Kaka, 

Thank you for contacting us. 

I am not quite sure what is precisely your case. Can you please provide more information on how are you populating RadGridView, are you using some View Definition and precisely which header you would like to hide.

In general, you can hide all column headers by setting the ShowColumnHeaders property to false:

this.radGridView1.ShowColumnHeaders = false;

I am looking forward to your reply.

Hi Ralista,

Yes I'm using ColumnGroupsViewDefinition.

ColumnGroupsViewDefinition view = new ColumnGroupsViewDefinition();

view.ColumnGroups.Add(new GridViewColumnGroup("User Details"));
view.ColumnGroups[1].ShowHeader = false;

view.ColumnGroups[1].Rows.Add(new GridViewColumnGroupRow());
view.ColumnGroups[1].Rows[0].Columns.Add(radGridView_Main.Columns["FirstName"]);

view.ColumnGroups[1].Rows.Add(new GridViewColumnGroupRow());
view.ColumnGroups[1].Rows[0].Columns.Add(radGridView_Main.Columns["LastName"]);

view.ColumnGroups[1].Rows.Add(new GridViewColumnGroupRow());
view.ColumnGroups[1].Rows[1].Columns.Add(radGridView_Main.Columns["Info"]);

Currently i have this (Current.png), as you can see there is info column. I want to hide the header so it will be like (Result.png).
Is that possible?

Thanks,

Hi Kaka, 

Thank you for your reply and provided images which helped me to understand your case better. 

You can subscribe to ViewRowFormatting event and set the Visibility property of Info column to Collapsed and change the MinSize property of another 2 columns (FirstName and LastName). You can use the following code snippet: 

void radGridView1_ViewCellFormatting(object sender, CellFormattingEventArgs e)
        {
            if (sender is GridHeaderCellElement)
            {
                if (e.Column.Name == "Title")
                {
                    e.CellElement.Visibility = Telerik.WinControls.ElementVisibility.Collapsed;
                }
                else
                {
                    e.CellElement.ResetValue(LightVisualElement.VisibilityProperty, Telerik.WinControls.ValueResetFlags.Local);
                }

                if (e.Column.Name == "FirstName" || e.Column.Name == "LastName")
                {
                    e.CellElement.MinSize = new Size(0, 57);
                }
                else
                {
                    e.CellElement.ResetValue(LightVisualElement.MinSizeProperty, Telerik.WinControls.ValueResetFlags.Local);
                }
            }
        }

I also attached my sample demo project. 

Should you have further questions, I would be glad to help.
