[Solved] GridTemplateColumn sortable with a LinkButton?

[Laz]

Hi to all,

it is not possible for me to make a GridTemplateColumn sortable with a LinkButton - control inside?

For my RadGrid i have set the attributes AllowMultiColumnSorting="true" and have define a <SortExpressions> Tag for a default sortexpression.

I don´t know if this information is important for problem solving?

The GridTemplateColumn with the UniqueName="WText" is not sortable in my example code

            <telerik:RadGrid ID="rdgWI"
                             runat="server"
                             AutoGenerateColumns="False"
                             GridLines="None"
                             onneeddatasource="rdgWI_NeedDataSource"
                             PageSize="8"
                             AllowSorting="True"
                             Width="100%">
                <HeaderContextMenu>
                    <CollapseAnimation Type="OutQuint" Duration="200"></CollapseAnimation>
                </HeaderContextMenu>

                <ClientSettings>
                    <Scrolling AllowScroll="True" UseStaticHeaders="true" />
                    <ClientEvents OnGridCreated="GetGridObject"></ClientEvents>
                </ClientSettings>

                <MasterTableView ClientDataKeyNames="WRhText, WiRhTask, WId, WText" ShowHeadersWhenNoRecords="true" AllowMultiColumnSorting="true" ShowHeader="true" runat="server" Width="99%">

                    <RowIndicatorColumn>
                        <HeaderStyle Width="20px"></HeaderStyle>
                    </RowIndicatorColumn>
                    <ExpandCollapseColumn>
                        <HeaderStyle Width="20px"></HeaderStyle>
                    </ExpandCollapseColumn>
                   <SortExpressions>
                        <telerik:GridSortExpression FieldName="WRhText" SortOrder="Ascending" />
                    </SortExpressions>
                    <Columns>
                        <telerik:GridBoundColumn DataField="WId" UniqueName="WId" Visible="false">
                        </telerik:GridBoundColumn>
                        <telerik:GridTemplateColumn HeaderText="Category" SortExpression="WRhText"
                            UniqueName="WCategory" DataField="WRhText" Visible="false">
                            <ItemTemplate>
                                <asp:Label ID="lblWCategory" runat="server" CssClass="DefaultText"
                                    Text='<%# GetWorklistTypText(Eval("WRhTask")) %>' />
                            </ItemTemplate>
                        </telerik:GridTemplateColumn>
                        <telerik:GridTemplateColumn HeaderText="Description" SortExpression="WText"
                            UniqueName="WText" >
                            <ItemTemplate>
                                <asp:LinkButton ID="lbWText" runat="server"
                                    CommandArgument='<%# Eval("WId") %>'
                                    CommandName="ShowDetails"
                                    Text='<%# Eval("WText") %>' OnCommand="btnShowDetails">
                                </asp:LinkButton>
                        </ItemTemplate>
                        </telerik:GridTemplateColumn>
                    </Columns>
                </MasterTableView>
                <FilterMenu>
                    <CollapseAnimation Type="OutQuint" Duration="200"></CollapseAnimation>
                </FilterMenu>
            </telerik:RadGrid>

Thank for your help

Hi Laz,

To add a sort LinkButton to a TemplateColumn in the Grid you should set the CommandName property to "Sort" and the sort expression as the CommandArgument for the button. RadGrid can then handle the sorting automatically when the user clicks the button.

Hi,

i have followed your notice. But why the SortIcon isn´t show, and why isn´t a colum color shown?

I set ShowSortIcon="true" but no SortIcon is shown?

 <telerik:GridTemplateColumn HeaderText="Description" DataField="WText" SortExpression="WText" ShowSortIcon="true"
                            UniqueName="WText">
                            <HeaderTemplate>
                                <asp:LinkButton ID="SortButton"
                                                runat="server"
                                                Text="Decision"
                                                ToolTip="Click to sort"
                                                CommandName='Sort'
                                                CommandArgument='WText'>
                                </asp:LinkButton>
                            </HeaderTemplate>
                            <ItemTemplate>
                                <asp:LinkButton ID="lbWText" runat="server"
                                    CommandArgument='<%# Eval("WId") %>'
                                    CommandName="ShowDetails"
                                    Text='<%# Eval("WText") %>' OnCommand="btnShowDetails">
                                </asp:LinkButton>
                            </ItemTemplate>
</telerik:GridTemplateColumn>

Thank you in advance
