RadTreeList's item template binding RadTextBox

[Sophia]

Hi,

I have met issues for binding RadTextBox as TreeListTemplateColumn.
1. Which sever side event can be triggered when text box value changed?
2. How to auto select current tree list row as well when the text box is focused?
3. This tree list is in the radwizard as one step. Every time I have to press enter key to fire RadTextBoxSN_TextChanged, ance once it fired, the page will automatically move to next wizard step. I wrote the manual next button event for wizard and no idea how this happened. Please help.

<telerik:TreeListTemplateColumn HeaderStyle-Width="170px" DataField="LotSerialNumber" UniqueName="LotSerialNumber" HeaderText="Lot/Serial Number">
                                                    <ItemTemplate>
                                                        <div style="text-wrap: none; word-break: keep-all; table-layout: fixed">
                                                            <telerik:RadTextBox ID="RadTextBoxSN" runat="server" OnTextChanged="RadTextBoxSN_TextChanged" ToolTip='<%# Eval("TXN_ID")%>' Text='<%# Eval("LotSerialNumber")%>' Width="125px">
                                                            </telerik:RadTextBox>
                                                            <asp:LinkButton ID="btnSearch" runat="server">
                                                    <img style="border: 0px; vertical-align: bottom" src="~/../Images/search.gif" />
                                                            </asp:LinkButton>
                                                            <asp:LinkButton ID="btnValid" runat="server" Visible="false" Enabled="false">
                                                    <img id="ImgValid" style="border: 0px; vertical-align: bottom" src="~/../Images/success.gif" />
                                                            </asp:LinkButton>
                                                            <asp:LinkButton ID="btnInvalid" runat="server" Visible="false" Enabled="false">
                                                    <img id="ImgInvalid" style="border: 0px; vertical-align: bottom" src="~/../Images/error.gif" />
                                                            </asp:LinkButton>
                                                        </div>
                                                    </ItemTemplate>
                                                </telerik:TreeListTemplateColumn>

Hi Sophia,

You will need to enable the AutoPostBack property to true when using the OnTextChanged server-side event handler. I've created a sample RadTreeList sample to demonstrate how you can achieve the first two requirements. As for the issue from the third point, you can place a temporary button before the wizard definition and see whether this will change something.

Hope this helps.
