[Solved] grid filter labels

[Mark]

Hi,
        I was wondering if there was any way that with the grid filtering, it would be possible to display a label of some sort next to/above/below the filter that would show which filter option the user has chosen (e.g. contains, equal to, beginswith etc)

Thanks

Hello Robert,

I tried adding Label control beside each filtertextbox and set the text according to current filter function in order to achieve the functionality. Here is my code.

C#:

    protected void RadGrid1_ItemCreated(object sender, Telerik.Web.UI.GridItemEventArgs e)
    {
        if( e.Item is GridFilteringItem)
        {
            GridFilteringItem filterItem = (GridFilteringItem)e.Item;
            foreach (GridColumn col in RadGrid1.MasterTableView.Columns)
            {
                Label lbl = new Label();
                lbl.ID = col.UniqueName.ToString() + "Filter";
                filterItem[col.UniqueName].Controls.Add(lbl);
            }
        }
    }
    protected void RadGrid1_PreRender(object sender, EventArgs e)
    {
        if(check)
        {
            GridFilteringItem filterItem = (GridFilteringItem)RadGrid1.MasterTableView.GetItems(GridItemType.FilteringItem)[0];
            Label lbl = (Label)filterItem.FindControl((colName) + "Filter");
            lbl.Text = filter;
        }
    }
    string colName, filter;
    bool check = false;
    protected void RadGrid1_ItemCommand(object source, GridCommandEventArgs e)
    {
        if (e.CommandName == RadGrid.FilterCommandName)
        {
            Pair filterPair = (Pair)e.CommandArgument;
            colName = filterPair.Second.ToString();
            filter = filterPair.First.ToString();
            check = true;
        }
    }

Shinu,
           Did you have to change the source code of the grid itself as this doesn't compile when putting the code into the code behind of a form. Also are we allowed to change the Telerik source code.

Thanks

Hello Robert,

The code snippet provided by Shinu looks correct. What type of errors you receive when you plug it on your page? I will appreciate if you share the stack trace of these exceptions to assist you address them.

You can change the source code of the controls, however thus you are not entitled to receive support concerning the modifying codebase and you will need to re-apply the chages manually for each future upgrade of RadControls for ASP.NET AJAX.

Best regards,
Sebastian
