Filter & Paging not working in Radgrid

[Suhail]

Hi,
I am working on Project which has a Radgrid, project was running successfully and the out come is alright. But my problem is filtering and paging is not working.

<telerik:RadGrid ID="RadGrid1" Skin="WebBlue" runat="server" AllowFilteringByColumn="true" AutoGenerateColumns="true" ShowStatusBar="True" GridLines="None" AllowPaging="true" PageSize="20" AllowSorting="True" onitemdatabound="RadGrid1_ItemDataBound" EnableLinqExpressions ="false"> 

<PagerStyle Mode="NextPrevAndNumeric" />
<GroupingSettings CaseSensitive="false" /> 

<MasterTableView AutoGenerateColumns="false" EditMode="InPlace" AllowFilteringByColumn="True" 
ShowFooter="True" TableLayout="Auto" AllowSorting="true" AllowPaging="true" PageSize="20">  

<Columns>

<telerik:GridBoundColumn FilterControlWidth="50px" DataField=" total_float " HeaderText="Total Float" SortExpression=" total_float " UniqueName=" total_float ">
</telerik:GridBoundColumn> 

</Columns>
</MasterTableView>
</telerik:RadGrid> 

 

 

 

 

 

This is my code and i placed only one row for sample. 

Protected Sub RadGrid1_PreRender(ByVal sender As Object, ByVal e As EventArgs)
RadGrid1.MasterTableView.AllowFilteringByColumn = True
RadGrid1.Rebind()
End Sub  

 

 

 

 

 

Also i placed this in my code(VB) behind file.
Can any one help me, Thanks in advance.

Hello Suhail,

The issue occures because you are binding the grid using Simple data binding technique. If you are using any advanced feature in grid(like paging), then a better approach is binding RadGrid using "AdvancedData binding" using NeedDataSource event.

For more information about this can be available here.

Advanced Data-binding (using NeedDataSource event).

Grid / Advanced Data Binding.

Thanks,

hi, 
I used radgrid contrlols and everytime i click the numeric page it reload/display only the first data of the grid.
and the filtering is working but the problem is it postback the whole page instead of refreshing the datagrid only.

 <%--control for the ajax postback--%>
        <telerik:radajaxmanager ID="SurveyData_RadAjaxManager" runat="server">
                <AjaxSettings>




                    <telerik:AjaxSetting AjaxControlID="SurveyData_RadGrid">
                        <UpdatedControls>
                            <telerik:AjaxUpdatedControl ControlID="SurveyData_RadGrid" LoadingPanelID="SurveyData_RadAjaxLoadingPanel" />
                        </UpdatedControls>
                    </telerik:AjaxSetting>
                    <telerik:AjaxSetting AjaxControlID="lnkSearch">
                        <UpdatedControls>
                            <telerik:AjaxUpdatedControl ControlID="SurveyData_RadGrid" LoadingPanelID="SurveyData_RadAjaxLoadingPanel" />
                        </UpdatedControls>
                    </telerik:AjaxSetting>

                </AjaxSettings>
        </telerik:radajaxmanager>
     <telerik:radajaxloadingpanel ID="SurveyData_RadAjaxLoadingPanel" runat="server" />
  <telerik:RadGrid ID="SurveyData_RadGrid" runat="server" EnableEmbeddedSkins="false" AllowPaging="true" PageSize="10" 
            AutoGenerateColumns="false"
            OnNeedDataSource="SurveyData_RadGrid_NeedDataSource" Font-Names="Arial" Font-Size="11pt"
            Width="1200px" OnItemDataBound="SurveyData_RadGrid_ItemDataBound">

Hi Suhail,

I have created a sample RadGrid web site using the provided code. On my side everything works as expected. Could you please check out the attached application and try to distinguish the crucial differences between our projects.
