Programmatically add filters then disable user from changing

[Shaun]

Hi,

I'm using a Gridview which I filter programmatically based on input from another control, this works well.
But is it possible to prevent the user from doing their own filtering on the same grid, I still want to show the column headers just want to remove the filter icon and or functionality.

Cheers
Shaun

Hello Shaun,

Thank you for writing.

There are two ways to hide the filter buttons in header cells:
1. You can set ShowHeaderCellButtons property of MasterTemplate:

this.radGridView1.MasterTemplate.ShowHeaderCellButtons = false;

2. Through the ViewCellFormating event of RadGridView

Note that if you are using Filtering Row you can hide its filter buttons only through the ViewCellFormating event of RadGridView. For example:

void radGridView1_ViewCellFormatting(object sender, Telerik.WinControls.UI.CellFormattingEventArgs e)
{
    //Hidding buttons in headers
    if (e.CellElement is GridHeaderCellElement)
    {
        e.CellElement.Children[0].Visibility = Telerik.WinControls.ElementVisibility.Collapsed;
    }

    //Hidding buttons in Filtering Row
    if (e.CellElement is GridFilterCellElement)
    {
        GridFilterButtonElement button = e.CellElement.Children[0] as GridFilterButtonElement;
        if (button != null)
        {
            foreach (RadElement item in button.Children)
            {
                item.Visibility = ElementVisibility.Collapsed;
            }
        }
    }
}

Attached is demo project that comprises the code above.

I hope this helps. Let me know if you have any additional questions.
