Grid does perform sort or paging in ajax mode

[Denis Buchwald]

Hi everyone,

I am obviously not seeing something here. I have a simple grid instance with its the necessary ajaxsettings declared:

Ajax Setting for grid:

<telerik:RadAjaxManager runat="Server" ID="RadAjaxManager1">
        <AjaxSettings>
            <telerik:AjaxSetting AjaxControlID="UserView">
                <UpdatedControls>
                    <telerik:AjaxUpdatedControl ControlID="UserView" LoadingPanelID="RadAjaxLoadingPanel1" />
                </UpdatedControls>
            </telerik:AjaxSetting>
        </AjaxSettings>
    </telerik:RadAjaxManager>

Grid instance: (allowsort and allowpaging both = true)

<telerik:RadGrid ID="UserView" GridLines="None" runat="server" AllowPaging="True"

                AutoGenerateColumns="False" Skin="Windows7" AllowSorting="true" Width="722" OnNeedDataSource="UserViewNeedDataSource" PageSize="20">

                <PagerStyle Mode="NextPrevAndNumeric"/>

                <MasterTableView Width="722">

                    <Columns>

                        <telerik:GridBoundColumn DataField="FullName" HeaderText="Name" SortExpression="FullName"

                            UniqueName="FullNameColumn" />

                        <telerik:GridBoundColumn DataField="UserName" HeaderText="User Name" SortExpression="UserName"

                            UniqueName="AdUserNameColumn" />

                        <telerik:GridBoundColumn DataField="Domain" HeaderText="Domain" SortExpression="Domain"

                            UniqueName="AdDomainColumn" />

                    </Columns>

                </MasterTableView>

            </telerik:RadGrid>

<telerik:RadGrid ID="UserView" GridLines="None" runat="server" AllowPaging="True"
                AutoGenerateColumns="False" Skin="Windows7" AllowSorting="true" Width="722" OnNeedDataSource="UserViewNeedDataSource" PageSize="20">
                <PagerStyle Mode="NextPrevAndNumeric"/>
                <MasterTableView Width="722">
                    <Columns>
                        <telerik:GridBoundColumn DataField="FullName" HeaderText="Name" SortExpression="FullName"
                            UniqueName="FullNameColumn" />
                        <telerik:GridBoundColumn DataField="UserName" HeaderText="User Name" SortExpression="UserName"
                            UniqueName="AdUserNameColumn" />
                        <telerik:GridBoundColumn DataField="Domain" HeaderText="Domain" SortExpression="Domain"
                            UniqueName="AdDomainColumn" />
                    </Columns>
                </MasterTableView>
            </telerik:RadGrid>

Assignment of data:

protected void Page_Load(object sender, EventArgs e)
        {
            if(!IsPostBack)
            {
                GetUsers();
            }
        }

        private void GetUsers()
        {
            UserView.DataSource = _client.GetUsers(null);

        }

And from the documentation, it says the OnNeedDataSource event will fire after a page or sort event, so I have a handler:

protected void UserViewNeedDataSource(object sender, GridNeedDataSourceEventArgs e)

        {

            GetUsers();

        }

protected void UserViewNeedDataSource(object sender, GridNeedDataSourceEventArgs e)
        {
            GetUsers();
        }

The ajax call is happening, the event handler is being hit, but nothing happens. No sort, no paging.

Feedback would be appreciated. Version of control suite: v2010.2.929.40

Cheers,

Derek

Hello Derek,

You can try handling the NeedDataSource event only and remove the code on Page.Load and see whether it makes any difference.

All the best,
