it sorts only single colum so whts going wrong ??

my code is

 

protected void RDGridEstimate_SortCommand(object source, GridSortCommandEventArgs e)

 

{

 

RadGrid RDGridEstimate = (RadGrid)((Telerik.Web.UI.RadGrid)(source));

 

 

switch (e.OldSortOrder)

 

{

 

case GridSortOrder.None:

 

sortExprEstim.FieldName = e.SortExpression;

sortExprEstim.SortOrder =

GridSortOrder.Ascending;

 

e.Item.OwnerTableView.SortExpressions.AllowMultiColumnSorting =

true;

 

e.Item.OwnerTableView.SortExpressions.AddSortExpression(sortExprEstim);

 

break;

 

 

case GridSortOrder.Ascending:

 

sortExprEstim.FieldName = e.SortExpression;

sortExprEstim.SortOrder =

GridSortOrder.Descending;

 

e.Item.OwnerTableView.SortExpressions.AllowMultiColumnSorting =

true;

 

e.Item.OwnerTableView.SortExpressions.AddSortExpression(sortExprEstim);

 

break;

 

 

case GridSortOrder.Descending:

 

sortExprEstim.FieldName = e.SortExpression;

sortExprEstim.SortOrder =

GridSortOrder.Ascending;

 

e.Item.OwnerTableView.SortExpressions.AllowMultiColumnSorting =

true;

 

e.Item.OwnerTableView.SortExpressions.AddSortExpression(sortExprEstim);

 

break;

 

}

e.Canceled =

true;

 

RDGridEstimate.Rebind();

}


 

 

protected void RDGridEstimate_NeedDataSource(object source, GridNeedDataSourceEventArgs e)

 

{

 

try

 

{

iInvcoID = (

Int32)ViewState["InvcoID"];

 

dsEstimate = moAnalystSummaryBL.GetEstimateDetails(iInvcoID);

 

RadGrid RDGridEstimate = (RadGrid)((Telerik.Web.UI.RadGrid)(source));

 

 

if (dsEstimate.Tables[0] != null && dsEstimate.Tables[0].Rows.Count > 0)

 

{

RDGridEstimate.DataSource = dsEstimate.Tables[0];

}

}

 

catch (Exception ex)

 

{

moErrorLog.sErrorMsg = ex.ToString();

moErrorLog.WriteErrorLog();

}

}

Hello Mugdha,

Could you please confirm that you set the AllowMultiColumnSorting property of the of the MasterTableView of the inner RadGrid to true?

Best wishes,

Hi Mugdha,

Can you post the grid declaration as well, or send us a sanmple illustrating your scenario and the described issue, so I can debug it locally and see what could have gone wrong there?

Looking forward your reply,
Iana
