[Solved] Weird error in Radgrid Sorting..

[Natraj T]

Hi,

I'm using Rad grid in one my page. The page has a master page and I placed the grid in its child page. I'm binding the grid with the below code, since the code is called on the search button click event , we placed this separately
 

function BindUnAssignedPeopleGrid(result) {
var grid = $find("<%= grdUnassigned.ClientID %>")
var masterTableView = grid.get_masterTableView();
RemoveNoRecordRow(masterTableView.get_element());
if (result == null || result == '' || result == 'undefined') {
result = new Array();
}
masterTableView.set_dataSource(result);
masterTableView.dataBind();
}

and the designer page grid

<telerik:RadGrid ID="grdUnassigned" runat="server" Height="253px" AutoGenerateColumns="False"
GridLines="None" AllowMultiRowSelection="True" Skin="Vista" AllowSorting="true" OnSortCommand="grdUnassigned_SortCommand">
<MasterTableView DataKeyNames="PersonID,Name" TableLayout="Fixed" ClientDataKeyNames="PersonID,Name">
<Columns>
<telerik:GridBoundColumn DataField="Name" HeaderText="Name" ItemStyle-Width="100%">
</telerik:GridBoundColumn>
</Columns>
<RowIndicatorColumn>
<HeaderStyle Width="30px"></HeaderStyle>
</RowIndicatorColumn>
<ExpandCollapseColumn>
<HeaderStyle Width="30px"></HeaderStyle>
</ExpandCollapseColumn>
</MasterTableView>
<ClientSettings AllowColumnHide="True" EnablePostBackOnRowClick="false">
<Selecting AllowRowSelect="True" />
<Scrolling AllowScroll="True" UseStaticHeaders="True" />
</ClientSettings>
<FilterMenu EnableTheming="True">
<CollapseAnimation Type="OutQuint" Duration="200"></CollapseAnimation>
</FilterMenu>
<FilterItemStyle BackColor="#CCFFFF" />
</telerik:RadGrid>

and in serverside sorting( we need everything to be done in client side, help me in this to sort in client side itself)

protected void grdUnassigned_SortCommand(object source, GridSortCommandEventArgs e)
{
try 
{

if (!e.Item.OwnerTableView.SortExpressions.ContainsExpression(e.SortExpression))
 {
GridSortExpression sortExpr = new GridSortExpression();
sortExpr.FieldName = e.SortExpression;
sortExpr.SortOrder = GridSortOrder.Descending;
e.Item.OwnerTableView.SortExpressions.AddSortExpression(sortExpr);
}
}
catch (Exception ex)
 
{
}}

but when i do sorting i'm getting "Sys.webforms.pagerequestmanagerparserErrorexception " error. please help me to solve this. I need everything to be done in client side.

Thanks in advance

Its urgent please help me ASAP.

nobody there to help me,  Ok

I have added the below code
.......
<ClientEvents OnCommand="grdUnassigned_Command" />
................

 and 

var sortGrid = null; //the sort method call the same function again, to avoid that we used this variable
            function grdUnassigned_Command(sender, args) {
                try {
                    if (sortGrid != 1) {
                        if (args.get_commandName() == "Sort") {
                            var masterTableView = sender.get_masterTableView();
                            var sortExpressions = sender.get_masterTableView().get_sortExpressions();
                            var sortExpressionsAsSQL = sortExpressions.toString();
                            sortGrid = 1;
                            masterTableView.sort(sortExpressionsAsSQL);
                        }
                    }
                    sortGrid = null;
                } catch (e) {
                    alert(e);
                }
                finally {
                }
            }

Still I'm getting error, now something like COM error. The above function execuets well, after this function the control goes to some dynamic created scriptmanager page, after that COM error is occured. The sad part is, error is returned as null object, so i'm not able to fighre the error also( we are using page level error set in web.config)

Please help me in this

Hi Natraj T,

From your code snippets I see that you bind the grid instance on the client. Therefore, you will need to implement sorting using WebServices or page methods as illustrated on this online demo of the product:

http://demos.telerik.com/aspnet-ajax/grid/examples/client/databinding/defaultcs.aspx

Alternatively, consider implementing declarative client-side binding (if applicable) as demonstrated on this example:
