I have problem get sorting working. Code is below:

    <telerik:RadGrid ID="RadGridList" runat="server" AutoGenerateColumns="false" AllowSorting="true" AllowPaging="true" PageSize="20" ShowGroupPanel="true" AllowFilteringByColumn="true">
        <GroupingSettings ShowUnGroupButton="true" />
        <MasterTableView GroupLoadMode="Client" TableLayout="Fixed" EnableGroupsExpandAll="true" AllowCustomSorting="true">
            <GroupByExpressions>
                <telerik:GridGroupByExpression>
                    <SelectFields>
                        <telerik:GridGroupByField FieldAlias="Name" FieldName="Name" />
                    </SelectFields>
                    <GroupByFields>
                        <telerik:GridGroupByField FieldName="Name" SortOrder="Descending" />
                    </GroupByFields>
                </telerik:GridGroupByExpression>
            </GroupByExpressions>
            <Columns>
                <telerik:GridBoundColumn DataField="Name" HeaderText="Name" AllowSorting="true"></telerik:GridBoundColumn>
                <telerik:GridBoundColumn DataField="Id" HeaderText="ID"></telerik:GridBoundColumn>
            </Columns>
        </MasterTableView>
        <GroupingSettings ShowUnGroupButton="true" />
        <ClientSettings AllowDragToGroup="true">
            <Selecting AllowRowSelect="true" />
        </ClientSettings>
    </telerik:RadGrid>

Sorting in GroupByExpression tag does work. The column sorting doesn't work. Any idea is appreciated!

Hi Konstantin Dikov
Thank you for reply, but in previous post i mentioned that i have cast string to date in sql query, but this time i m saving date in encrypted format and it can't decrypted in sql query so i m decrypting in cs code.
is there any way to cast it to date formate after decrypting and bind with grid. Below is my code for binding data to Grid

protected void gdshow_ItemDataBound(object sender, GridItemEventArgs e)
        {
            try
            {
                if (isExcelExport && e.Item is GridDataItem)
                {
                    foreach (TableCell cell in e.Item.Cells)
                    {

                        cell.Style["mso-number-format"] = @"\@";

                    }
                }

                if (e.Item.ItemType == GridItemType.Item || e.Item.ItemType == GridItemType.AlternatingItem)
                {
                    GridDataItem dataBoundItem = e.Item as GridDataItem;

                    foreach (GridColumn column in dataBoundItem.OwnerTableView.RenderColumns)
                    {
                        if (column.HeaderText.Trim().ToLower().Contains("date"))
                        {

                            dataBoundItem[column.UniqueName].Text = dataBoundItem[column.UniqueName].Text.Replace(" 12:00:00 AM", "").Replace("1/1/1900", "");
                        }
                    }

                }
            }
            catch (Exception)
            {

            }

        }

Thank yoiu

Hi Shafqat,

Can you please elaborate what you mean by "encrypted dates format" and why you need to store the values in such manner in your database? As for the sorting, the RadGrid will sort the values based on the values in the DataSource, so the only options that you have is to either change the database column to store the values as dates or fill a DataTable with the original values and modify them before setting that DataTable as a DataSource of the grid.
