How to mark filters that are currently applied?

[Martin]

I have RadGrid with filters. I need to change style/filterbutton to show user which filter is currently applied.

I need to change when is fired OnItemCommand.
if(e.CommandName == RadGrid.FilterCommandName)
{ Change style to current filter.}

Actually this information is insufficient for me.

Hi Princy,
Thanks for your replay. How ever I think it is not exactly what I expected. I need to change style during filtering. So as i filter by some column I need to change style of textbox/image which is filter is used.

OnItemCmmand is not working, so style is not change. At beggining I try to change BackColor of textbox.

If there is no answer I suppose to think that it is impossible?

Hi Martin,

Give a try the following code snippet.

CS:

  protected void RadGrid1_ItemCommand(object source, GridCommandEventArgs e)
    {
        if (e.CommandName == RadGrid.FilterCommandName)
        {
            GridFilteringItem filter = (GridFilteringItem)e.Item;
            string strtxt = ((System.Web.UI.Pair)(e.CommandArgument)).Second.ToString();
            TextBox txtbx = (TextBox)filter[strtxt].Controls[0];
            txtbx.BackColor = System.Drawing.Color.Red;

        }


    }

Thanks
Princy.

Hi Princy,
This is my code :

    protected void OnItemCommand_Click(object sender, GridCommandEventArgs e)
    {
        if (e.CommandName == RadGrid.FilterCommandName)
        {
            Pair filter = (Pair)e.CommandArgument;
            GridFilteringItem filterItem = e.Item as GridFilteringItem;
            TextBox filterTextBox = (TextBox)(filterItem)[filter.Second.ToString()].Controls[0];

            filterTextBox.BackColor = System.Drawing.Color.Red;
            string filterPattern = filterTextBox.Text;

            if (filter.First.ToString() != "NoFilter")
            {
                BindGridView(filter.Second.ToString(), filterPattern);
            }
            else
            {
                BindGridView(filter.Second.ToString(), string.Empty);
            }
        }
    }

So it doesn't work. BindGridView() i rebind datasource.
