Dynamic RedGrid FilterTemplate

[Alic W]

Hi,

I am trying to create my own filter template for a certain column in RadGrid dynamically. I tried to do this on Load/Render/init, still to no avail.

myColumn.FilterTemplate = new CustomGridTemplate();

...
public class CustomGridTemplate: ITemplate
    {
        public CustomGridTemplate()
        {
        }

        public void InstantiateIn(System.Web.UI.Control container)
        {
            TextBox tbx = new TextBox();
            tbx.Text = "Test";
            container.Controls.Add(tbx);
        }
   }

The grid filter shows up with the standard controls for that column - the breakpoint in CustomGridTemplate class constructor doesn't even get hit. I've seen an example for regular templated columns, but I am using AutoGeneratedColumns. I would appreciate your comments.

Hi Pavina,

Using the example I was able to create a custom filter textbox. I now want to put the filter menu besides the custom filter. Just like how the normal radgrid does the filtering by selecting the menu. Do you have any working code that does this?

Thanks,
Raji

Hi Raji,

To achieve your goal you could add Image Button and create your own RadContextMenu inside the FilterTemplate to cover the required functionality.
