  1. POGet Selected Row On Button Click
    text
    copied!<p>I have a GridView which does the following:</p> <pre><code>protected override void Render(System.Web.UI.HtmlTextWriter textWriter) { foreach (GridViewRow gvRow in gvNotifications.Rows) { if (gvRow.RowType == DataControlRowType.DataRow) { gvRow.Attributes.Add("onmouseover", "this.previous_color=this.style.backgroundColor;this.style.backgroundColor='#FFFF99';this.style.cursor='hand';"); gvRow.Attributes.Add("onmouseout", "this.style.backgroundColor=this.previous_color;"); gvRow.Attributes["onclick"] = ClientScript.GetPostBackClientHyperlink(gvNotifications, "Select$" + gvRow.RowIndex,true); } } base.Render(textWriter); } protected void gvNotifications_SelectedIndexChanged(object sender, EventArgs e) { gvNotifications.SelectedRowStyle.BackColor = Color.LightBlue; } </code></pre> <p>I have a button called btnTest and I would like to be able to cast the current row to my custom object. I have tried the following without any luck.</p> <pre><code>Customer currentRow = (Customer)gvNotifications.SelectedRow.DataItem; </code></pre> <p>'DataItem' is always null. I'm sure this is a easy fix but after Googling the problem I have yet to find anything that would work.</p> <p>Here is my GridView in the aspx:</p> <pre><code>&lt;asp:GridView ID="gvNotifications" runat="server" AutoGenerateColumns="false" GridLines="None" CssClass="mGrid" AlternatingRowStyle-BackColor="#F0F0F0" AllowPaging="true" AllowSorting="true" PagerStyle-CssClass="pgr" PageSize="25" OnPageIndexChanging="gvNotifications_PageIndexChanging" OnSorting="gvNotifications_Sorted" HeaderStyle-CssClass="srtAc" onselectedindexchanged="gvNotifications_SelectedIndexChanged"&gt; &lt;Columns&gt; &lt;asp:TemplateField HeaderText="Customer Id" SortExpression="CustomerId" HeaderStyle-ForeColor="WhiteSmoke"&gt; &lt;ItemTemplate&gt; &lt;%#Eval("CustomerId")%&gt; &lt;/ItemTemplate&gt; &lt;/asp:TemplateField&gt; &lt;asp:TemplateField HeaderText="Contact Name" SortExpression="ContactName" HeaderStyle-ForeColor="WhiteSmoke"&gt; &lt;ItemTemplate&gt; &lt;%#Eval("ContactName")%&gt; &lt;/ItemTemplate&gt; &lt;/asp:TemplateField&gt; &lt;/Columns&gt; &lt;/asp:GridView&gt; &lt;asp:Button ID="btnTest" runat="server" Text="Use" onclick="btnTest_Click" /&gt; </code></pre>
