Default Filter Error

[Jeff Reinhardt]

If I put the following in the ASPX:      <MasterTableView FilterExpression="([Active] = True)">     and put the CurrentFilterFunction="EqualTo" and CurrentFilterValue="True"  on the GridBoundColumn Named Active    The filter is set but does not filter the records.

If I put this in the codebehind on the NeedDataSource Method:

protected void rgManage_NeedDataSource(object source, Telerik.Web.UI.GridNeedDataSourceEventArgs e)
        {
            rgManage.DataSource = GetDataSet();
            if (!Page.IsPostBack)
            {
                rgManage.MasterTableView.FilterExpression = "([Active] = True)";
                GridColumn column = rgManage.MasterTableView.GetColumnSafe("Active");
                column.CurrentFilterFunction = GridKnownFunction.EqualTo;
                column.CurrentFilterValue = "True";
            }
        }

I get the following error on page load:

Expression expected

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: Telerik.Web.UI.ParseException: Expression expected


What am I missing here?   Active is a boolean datatype.

Have you tried setting the DataType of that column to boolean? Like so: DataType="System.Boolean".

That way the grid knows it's a boolean.

I hope that helps.

Yes, this did not work.  Still get the expression error.

Hello Jeff,

Try to set EnableLinqExpressions property of RadGrid as 'false' and check whether this eliminates the exception.

Hope this helps,
Princy.

That worked.  A little frustrating to have to know to turn that off for something so simple.   Thank you Princy.
