RadGrid created from code-behind not triggering filter postbacks

[Amod]

Hi,

I have a radgrid built completely from code-behind as a server-control. I am trying to add column filters to some of its columns. When I set the properties required for filtering (AllowFilteringByColumn on the grid) I see the filters on the columns. I then create the columns in code-behind - set the filter properties on them - and add it to the grid's column collection. When I type text in the filter column and press Enter the page/grid doesn't postback. Nothing happens. What am I missing in the below code?

The constructor that initializes the control


public RadGridOpportunity()

{

    this.ID = "grdOpportunity";

    this.MasterTableView.AutoGenerateColumns = false;

    this.MasterTableView.DataKeyNames = new string[] { "ID" };

    this.MasterTableView.Columns.Add(ColStatus());

    this.MasterTableView.HierarchyLoadMode = GridChildLoadMode.ServerBind;

    this.MasterTableView.NoRecordsTemplate = new TemplateNoRecords();

    this.ItemCommand += RadGridOpportunity_ItemCommand;           

    this.ItemCreated += RadGridOpportunity_ItemCreated;

    this.MasterTableView.NestedViewTemplate = new TemplateNestedView();

    this.NeedDataSource += RadGridOpportunity_NeedDataSource;

 

    //filtering

    this.AllowFilteringByColumn = true;

    this.MasterTableView.AllowFilteringByColumn = true;

}

 The column that is built and added to the columns collection-

protected GridColumn ColStatus()
{
    GridBoundColumn col = new GridBoundColumn();
    col.HeaderText = "Status";
    col.DataField = "Status";
    col.CurrentFilterFunction = GridKnownFunction.Contains;
    col.ShowFilterIcon = false;
    col.AutoPostBackOnFilter = true;
    col.DataType = Type.GetType("System.String");
    return col;
}

Hi Amod,

What event are you using to create the RadGrid control?

I tested the behavior with the RadGrid created in Page_Init and the filtering is working as expected on my end. Check out the attached sample for illustration.

Hi Viktor,

Thanks for your reply. Your sample works. I have the below hierarchy on the page.

++Page

++++RadTabStrip

++++++RadMultipage.RadPagView

++++++++PlaceHolder

++++++++++Dynamic RadGrid.

I am injecting the grid in the placeholder at runtime. If I remove the above hierarchy and inject the grid directly on the page it works. Otherwise it doesn't. The grid is initialized in the RadTabStrip's init event. Am I missing something here?

Hello Amod,

Try to use the Init event of the RadMultiPage control and see how the behavior changes. I tested the behavior and it is working as expected on my end. Check out the attached sample as reference.
