    <p>I want to assign a csharp variable to the element of asp page using javascript. It seems the assignement is not working in my code. </p> <p>Here it is: </p> <pre><code>document.getElementById('lbAccessories').innerHTML = '&lt;%#SelectLabel%&gt;'; </code></pre> <p>In my asp code i use:</p> <pre><code>&lt;asp:LinkButton ID="lbAccessories" runat="server" /&gt;' </code></pre> <p>I can't assign the value directly to the linkbutton using <code>Text='&lt;%#SelectLabel%&gt;'</code> because i want to make it more intelligent. </p> <p>Does anyone knows how to do with that? </p> <p>Thanks</p> <p><strong>Edit:</strong> </p> <p>Here is my code, I've tried to use <code>&lt;%=lbAccessories.clientId%&gt;</code>, but it generates an error : lbAccessories does not exist in the context.</p> <pre><code>&lt;script type="text/javascript"&gt; function function(Ref) { if ('&lt;%=TextBoxClientID%&gt;' == 'txtLink') { document.getElementById('lbAccessories').innerHTML = '&lt;%#SelectLabel%&gt;'; } else if ('&lt;%=TextBoxClientID%&gt;' == 'btnSearch') { document.getElementById('lbAccessories').innerHTML = '&lt;%#ViewDetail%&gt;'; } } &lt;/script&gt; </code></pre> <p><strong>Edit:</strong></p> <pre><code>&lt;asp:GridView ID="gv1" AutoGenerateColumns="false" runat="server" AllowPaging="true" OnPageIndexChanging="pic"&gt; &lt;Columns&gt; &lt;asp:TemplateField HeaderText=""&gt; &lt;ItemTemplate&gt; &lt;asp:LinkButton ID="lbAccessories" runat="server" OnClientClick='&lt;%#string.Format("passAccessory(\"{0}\");", Eval("Ref"))%&gt;'&gt;&lt;/asp:LinkButton&gt; &lt;/ItemTemplate&gt; &lt;/asp:TemplateField&gt; &lt;/Columns&gt; &lt;/asp:GridView&gt; </code></pre> <p>Edit:</p> <p>Thanks so much for everyone who had posted the suggestions. </p> <p>I have changed the javascript code to the following:</p> <pre><code>&lt;script type="text/javascript"&gt; function passAccessory(accessoryRef) { if ('&lt;%=TextBoxClientID%&gt;' == 'txtLink') { document.getElementById('&lt;%= gvAccessories.FindControl("lbAccessories").ClientID %&gt;').innerHTML = '&lt;%#SelectLabel%&gt;'; } else if ('&lt;%=TextBoxClientID%&gt;' == 'btnSearch') { document.getElementById('&lt;%= gvAccessories.FindControl("lbAccessories").ClientID %&gt;').innerHTML = '&lt;%#ViewDetail%&gt;'; } } &lt;/script&gt; </code></pre> <p>in <code>*.aspx.cs</code> file, i have added: <code>protected LinkButton lbAccessories { get; set; }</code> </p> <p>It throws an exception: </p> <blockquote> <p>Object reference not set to an instance of an object</p> </blockquote> <p>Anyone have ideas? Thanks so much</p> <p><strong>Edit:</strong></p> <p>Finally, we did it with csharp code. It's more flexable and manageable. My colleague helped me. Thank you all for your help!!!</p>

    3. COThis is a user control. Different pages include the user control. But the view is a little different when different pages are loaded. So i want to use javascript to judge different conditions and to show different content in the `LinkButton` which is located in a gridview.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
