Hi Neil,
Thank you for your interest in Syncfusion Products.
The issue reported by you, can be obtained when AllowFilter is enabled in TableDescriptor when ItemTemplate is defined. If the page contains ItemTemplates, then FilterBar should be enabled programmatically from code behind file. Please refer the sample below which illustrates this.
http://files.syncfusion.com/support/GGC.Web/7.1.0.30/F80072/main.htmThe Filtering mechanism work flow is as follows.
When a data source is set for a Grid and while rendering the data in each column will be read and the unique data will be populated to the filter combo box. Hence AllowFilter should be removed from TableDescriptor and should be enabled for the appropriate columns in code behind file. Please refer the code snippet to achieve this.
[ASPX]
AutoFormat="Office 2007 Blue" DataSourceCachingMode="viewState" ShowGroupDropArea="false">
....
[C#]
protected void Page_Load(object sender, EventArgs e)
{
this.GridGroupingControl.TableDescriptor.Columns[0].AllowFilter = true;
this.GridGroupingControl.TableDescriptor.Columns[1].AllowFilter = true;
this.GridGroupingControl.TableDescriptor.Columns[2].AllowFilter = true;
}
Please have a look at the above sample and if still the issue exists, could you please try reproducing it in the above sample and send us the modified sample so that we could sort out the cause of the issue and provide you a solution?
Please let me know if you have any other concerns.
Thanks,
Rekha
