    copied!<p>Here is the part of Repeater code that throws exception... "Computer.Administrators" is StringCollection object. Debugger shows that "AdminsEnumerator.Current" gets correct string value but when "txtAdministrators.Text" tries to set value - exception is thrown. Please help with ideas. </p> <pre><code>&lt;asp:Repeater ID="repeatAdministrators" OnItemDataBound="repeatAdministrators_ItemDataBound" runat="server"&gt; &lt;HeaderTemplate&gt; &lt;tr&gt; &lt;td class="formLabel"&gt; Administrators: &lt;/td&gt; &lt;td class="formInputText"&gt; &lt;/HeaderTemplate&gt; &lt;ItemTemplate&gt; &lt;asp:TextBox ID="txtAdministrators" runat="server" MaxLength="50" Enabled="False"&gt;&lt;/asp:TextBox&gt;&lt;br /&gt; &lt;/ItemTemplate&gt; &lt;FooterTemplate&gt; &lt;/td&gt; &lt;/tr&gt; &lt;tr&gt; &lt;/FooterTemplate&gt; &lt;/asp:Repeater&gt; </code></pre> <p>And here is code behind.</p> <pre><code> protected void btnPing_Click(object sender, EventArgs e) { //... repeatAdministrators.DataSource = Computer.Administrators; repeatAdministrators.DataBind(); } protected void repeatAdministrators_ItemDataBound(object sender, RepeaterItemEventArgs e) { TextBox txtAdministrators = e.Item.FindControl("txtAdministrators") as TextBox; StringEnumerator AdminsEnumerator = Computer.Administrators.GetEnumerator(); while (AdminsEnumerator.MoveNext()) { txtAdministrators.Text = AdminsEnumerator.Current; } } </code></pre>
