I have a grid where you select the grid item via a checkbox inside a templatecolumn, when you click on the checkbox it highlights the grid item and then i do other operations on the grid selected items.

The problem is that when you click one row via the checkbox other functionality does not work after that intial click, for example if i wanted to select another row via the checkbox it will not highlight the row and partial postback does not occur, i can resolve the issue by turning off ajax.

So basically you click any checkbox in any row and then functions do not work for instance the authorise command does not work, it is like the page invalid.

Attached grid html:

<telerik:RadGrid 
    ID="paymentsGrid" 
    runat="server"
    AllowSorting="False" 
    AllowPaging="False"
    AllowFilteringByColumn="False"
    AllowAutomaticInserts="True"
    AllowAutomaticUpdates="True"
    AllowAutomaticDeletes="True" 
    AutoGenerateColumns="False"
    MasterTableView-HeaderStyle-Wrap="false"
    MasterTableView-ItemStyle-Wrap="false" 
    GridLines="None" 
    ShowFooter="true"
    EnableLinqExpressions="false"
    onitemdatabound="paymentsGrid_ItemDataBound"
    OnItemCommand="paymentsGrid_OnItemCommand"
    ShowHeader="true"
    AllowMultiRowSelection="true">
      
    <MasterTableView CommandItemDisplay="Top">
      
     <CommandItemTemplate>
         <div style="margin:5px;padding:5px">
            <div style="float:right">
            <asp:LinkButton ID="lbAuthorise" runat="server" CommandName="Authorise" OnClientClick="javascript:if(!confirm('Are you sure you want to authorise the selected payments?')){return false;}">Authorise</asp:LinkButton>
            </div>
        </div>
  
         </CommandItemTemplate>  
           
        <RowIndicatorColumn>
            <HeaderStyle Width="20px"></HeaderStyle>
        </RowIndicatorColumn>
  
        <ExpandCollapseColumn>
            <HeaderStyle Width="20px"></HeaderStyle>
        </ExpandCollapseColumn>
          
        <Columns>
          
            <telerik:GridBoundColumn DataField="PeriodFrom" ReadOnly="true" UniqueName="PeriodFrom" HeaderText="From" DataFormatString="{0:dd/MM/yyyy}"></telerik:GridBoundColumn>

            <telerik:GridBoundColumn DataField="SiteName" ReadOnly="true" UniqueName="SiteName" HeaderText="Site"></telerik:GridBoundColumn>

            <telerik:GridBoundColumn DataField="ContractID" ReadOnly="true" Display="false" UniqueName="ContractID"></telerik:GridBoundColumn>
            <telerik:GridBoundColumn DataField="PaymentID" ReadOnly="true" Display="false" UniqueName="PaymentID"></telerik:GridBoundColumn>
             
            <telerik:GridTemplateColumn UniqueName="selectionColumn" AllowFiltering="false" HeaderStyle-Width="27px">
            <HeaderTemplate>
            <asp:CheckBox id="chkPaymentGridHeader" OnCheckedChanged="paymentsGrid_HeaderCheckChanged" AutoPostBack="True" runat="server"></asp:CheckBox>
            </HeaderTemplate>
            <ItemTemplate>
            <asp:CheckBox id="chkPaymentGridItem" OnCheckedChanged="paymentsGrid_ItemCheckChanged" AutoPostBack="True" runat="server"></asp:CheckBox>
            </ItemTemplate>
            </telerik:GridTemplateColumn
                      
        </Columns>
          
        <ItemStyle Wrap="False"></ItemStyle>
        <HeaderStyle Wrap="False"></HeaderStyle>
        <FooterStyle Wrap="false"></FooterStyle>
      
    </MasterTableView>
  
    
</telerik:RadGrid>


The checkbox events:
protected void paymentsGrid_HeaderCheckChanged(object sender, EventArgs e)
         {
             if ((sender as CheckBox).Checked)
             {
                 foreach (GridDataItem dataItem in paymentsGrid.MasterTableView.Items)
                 {
                     (dataItem.FindControl("chkPaymentGridItem") as CheckBox).Checked = true;
                     dataItem.Selected = true;
                 }
             }
             else
             {
                 foreach (GridDataItem dataItem in paymentsGrid.MasterTableView.Items)
                 {
                     (dataItem.FindControl("chkPaymentGridItem") as CheckBox).Checked = false;
                     dataItem.Selected = false;
                 }
             }
         }
  
         protected void paymentsGrid_ItemCheckChanged(object sender, EventArgs e)
         {
             bool itemIsChecked = (sender as CheckBox).Checked;
  
             ((sender as CheckBox).Parent.Parent as GridItem).Selected = (sender as CheckBox).Checked;
  
         }

Forgto to mention that this code works fine running from visual studio, it is once it is deployed to sharepoint 2007 that it has this ajax issue

Solved the issue

It was a rogue piece of javascript that sharepoint did not like.
