[Solved] Uncheck gridtemplatecolumn checkbox when row is deselected

[Laura]

I have a grid that has clientside selecting enabled. I have a client select column and also a grid template column which has an item template of an asp checkbox. I want to wire the onrowdeselected client event so that when the row is deselected, the grid template column checkbox is also un selected. I need both checkboxes since they both mean different things. The clientselectcolumn indicated that this record is selected, and the template column is used as a flag to save in a certain way. If the record is not selected, the flag has no meaning since it won't be saved, so I want to uncheck it. How do I uncheck the asp checkbox on deselecting the row? Here is my code:

Here is my grid:

               <telerik:RadGrid ID="RadGrid1" runat="server" AllowFilteringByColumn="True"  AllowMultiRowSelection="True"
                AllowSorting="True" DataSourceID="SqlDataSource1" GridLines="None" OnPreRender="packageGrid_PreRender"
                 OnItemDataBound="packageGrid_ItemDataBound">
                <ClientSettings>
                 <Selecting AllowRowSelect="true" EnableDragToSelectRows="true" />
                 <ClientEvents OnRowDeselected="rowDeselected" />
                </ClientSettings>
                <HeaderContextMenu EnableTheming="True" >
                    <CollapseAnimation Duration="200" Type="OutQuint" />
                </HeaderContextMenu>
                <MasterTableView AutoGenerateColumns="False" DataSourceID="SqlDataSource1">
                    <RowIndicatorColumn>
                        <HeaderStyle Width="20px" />
                    </RowIndicatorColumn>
                    <ExpandCollapseColumn>
                        <HeaderStyle Width="20px" />
                    </ExpandCollapseColumn>
                    <Columns>
                        <telerik:GridClientSelectColumn UniqueName="rowSelectColumn" HeaderText="Selected"> </telerik:GridClientSelectColumn>
                        <telerik:GridBoundColumn DataField="package_id" Display="false"></telerik:GridBoundColumn>
                        <telerik:GridBoundColumn DataField="package_name"
                            HeaderText="Package" SortExpression="package_name"
                            UniqueName="package_name">
                        </telerik:GridBoundColumn>

                        <telerik:GridBoundColumn DataField="package_cd" HeaderText="Package code"
                            SortExpression="package_cd" UniqueName="package_cd">
                        </telerik:GridBoundColumn>
                        <telerik:GridBoundColumn DataField="descriptions" HeaderText="descriptions"
                            SortExpression="descriptions" UniqueName="descriptions" Display="false">
                        </telerik:GridBoundColumn>
                        <telerik:GridBoundColumn DataField="pkg_type" HeaderText="pkg_type"
                            SortExpression="pkg_type" UniqueName="pkg_type" Display="false">
                        </telerik:GridBoundColumn>
                        <telerik:GridBoundColumn DataField="active" HeaderText="Active"
                            SortExpression="active" UniqueName="active">
                        </telerik:GridBoundColumn>
                        <telerik:GridTemplateColumn DataField="OPENS_transform_flag" UniqueName="OPENS_transform_flag" HeaderText="Write to OPENS AS IS">
                         <ItemTemplate>
                          <asp:CheckBox runat="server" ID="OPENS_transform_flag" />
                         </ItemTemplate>
                        </telerik:GridTemplateColumn>
                        <telerik:GridBoundColumn DataField="end_date" DataType="System.DateTime" Display="false"
                            HeaderText="end_date" SortExpression="end_date" UniqueName="end_date">
                        </telerik:GridBoundColumn>
                    </Columns>

                </MasterTableView>
                <FilterMenu EnableTheming="True">
                    <CollapseAnimation Duration="200" Type="OutQuint" />
                </FilterMenu>
            </telerik:RadGrid>

And here is the javascript for the onrowdeselected event. I do not know what to put for the last line to uncheck the checkbox...

        function rowDeselected(sender, eventArgs) {

            var dataItem = $get(eventArgs.get_id());
            var grid = sender;
            var MasterTable = grid.get_masterTableView();
            var row = MasterTable.get_dataItems()[eventArgs.get_itemIndexHierarchical()];
            var cell = MasterTable.getCellByColumnUniqueName(row, "OPENS_transform_flag");

            //  ??? What do I put here to uncheck this cell??? //

        }

Hello Laura,

You can access the checkbox in the template column in the row deselected client event and uncheck it as shown below:
js:

function rowDeselected(sender, eventArgs)
      {
            var dataItem = $get(eventArgs.get_id());
            var grid = sender;
            var MasterTable = grid.get_masterTableView();
            var row = MasterTable.get_dataItems()[eventArgs.get_itemIndexHierarchical()];

            var checkboxes = row._element.getElementsByTagName("INPUT");
            var index;
            for(index = 0; index < checkboxes.length; index++)
             {
               if(checkboxes[index].id.indexOf("OPENS_transform_flag")!=-1)
                   {
                       checkboxes[index].checked = false;
                   }
             }
        }

Thanks
Princy.
