Programatically create template filter on grid column

[Nicholas Walker]

Do you guys have a simple example of how to create a template filter on a grid column using a RadComboBox in the code-behind?  Been looking through the forum and docs and don't see one.

Thanks,

Hello Nick,

You can also check out the following forum link which provides with an example, how to create a filter template with a combobox dynamically:

Programatically created radgrid bound client side

This example works great !!

I have a tabstrip, each tab strip will contain a grid.  The number of tabs is not known at design time, the data will be retrieved at run time.  Because of this I am creating each grid programatically.  How do I add a filter on the server side that was previously defined on the client side as:

<custom:MyCustomFilteringColumn DataField="Name" HeaderText="Select Flight">

<HeaderStyle width="75px" horizontalalign="Center"/>

<ItemStyle width="75px" horizontalalign="Left"/>

<itemtemplate>

<%# Eval("Name") %>

</itemtemplate>

</custom:MyCustomFilteringColumn>

Any help would be greatly appreciated.

Hi Kevin,

Please examine the code snipped below and let me know if it helps to achieve your goal:
C#

protected override void OnInit(EventArgs e)
    {
        base.OnInit(e);
        BuildGrid();
    }

    private void BuildGrid()
    {
        RadGrid grid = new RadGrid();
        grid.ID = "RadGrid1";
        grid.AllowPaging = true;
        grid.AllowSorting = true;
        grid.NeedDataSource += new GridNeedDataSourceEventHandler(grid_NeedDataSource);

        GridBoundColumn id = new GridBoundColumn();
        id.DataField = "ID";
        id.HeaderText = "ID";
        grid.MasterTableView.Columns.Add(id);

        MyCustomFilteringColumn name = new MyCustomFilteringColumn();
        name.HeaderText = "Name";
        name.ItemTemplate = new MyItemTemplate("Name");
        grid.MasterTableView.Columns.Add(name);

        this.Controls.Add(grid);
    }

    void grid_NeedDataSource(object source, GridNeedDataSourceEventArgs e)
    {
        List<object> data = new List<object>();
        for (int i = 0; i < 20; i++)
        {
            data.Add(new { ID=i, Text = "Text " + i});
        }

        ((RadGrid)source).DataSource = data;
    }
}

public class MyItemTemplate : ITemplate
{

}

All the best,
