Question

Inside of a GridView’s TemplateField i have a HTML-TextArea:

<asp:TemplateField HeaderText="Message">
   <ItemTemplate>
      <textarea id="txtArStatusMsg" cols="20" rows="2" style="width: 99%"></textarea>
   </ItemTemplate>
</asp:TemplateField>

Q: how can i read the text of the text-area in the SelectedRow of the GridView?

Answer 1

Add runat="server" to the textarea and call FindControl("txtArStatusMsg") on the SelectedRow of the GridView.
To get the TextAreas‘s text, you need to cast it to a HtmlTextArea and read it’s Value property.

var text = ((HtmlTextArea)GridView1.SelectedRow.FindControl("txtArStatusMsg")).Value;
