I have a link button inside datalist, i need to change the name of link if user clicks that .

ASP.NET

      <asp:DataList ID="dlist" runat="server"
          onselectedindexchanged="dlist_SelectedIndexChanged" Width="192px"
          Height="80px" onitemcommand="dlist_ItemCommand">

          <ItemTemplate>

<li> <asp:LinkButton id="OpenClose" runat="server" OnClick="OpenClose_Click" AutoPostBack="true" Text="Close" CommandName="lnkreset"></asp:LinkButton></li>
    </ItemTemplate>

      </asp:DataList>

What I have tried:

protected void OpenClose_Click(object sender, EventArgs e)
{
if (OpenClose.Text == "Close")
{
OpenClose.Text = "Open";
}
else
{
OpenClose.Text = "Close";
}
}

sorry sir i need to solve in asp.net

That is asp.net! But it's using VB, not C#. It's not hard to convert, you'll have to do that. There are online converters if you get stuck. Google "vb to c#"

Solution 1

Take out the
OnClick="OpenClose_Click"
from your LinkButton definition, and instead do what you need within the DataList's onitemcommand function.
Within that, check for
if )e.coomandName = "lnkreset")
and then find the LinkButton control (e.Item.FindControl) and use that to change the Text property.
