How to disable hyperlink on LnkButton?-CodePudding

I have a table of data. One of the fields is UName. UName has hyperlink. I want to disable it in SOME rows.

I have two LnkButtons in ItemTemplate. When I remove first LnkButton in ItemTemplate, hyperlink from UName field is removed. Since I do not want to disable it for each row, I want to get a way to disable hyperlink from CodeBehind.

<telerik:GridTemplateColumn DataField="UName" GroupByExpression="UName" UniqueName="UName"
                                            InitializeTemplatesFirst="false" HeaderText="Name" CurrentFilterFunction="Contains">
                                            <HeaderStyle />
                                            <HeaderTemplate>
                                                <span onm ouseover='ShowColumnHeaderMenu(event,"UName")'>Name
                                                </span>
                                                <asp:Image ID="imgHeader1" ImageUrl="" Visible="false" runat="server" />
                                            </HeaderTemplate>
                                            <ItemTemplate>
                                                <LnkButton:LnkButton ID="HypUName" runat="server" style="white-space: nowrap" Text='<%# Server.HtmlEncode(Eval("UName").ToString()) %>'></LnkButton:LnkButton>
                                                 <LnkButton:LnkButton ID="LnkButton1" runat="server" Text='<%# Eval("UName").ToString() %>' Menuid="5"></LnkButton:LnkButton>
                                            </ItemTemplate>
                                        </telerik:GridTemplateColumn>

In summary, my goal is to disable LnkButton with ID "HypUName" from CodeBehind.

CodePudding user response：

You need to loop through find the control and disable it, if it passes what ever condition you are looking for. example below

protected void OnRowDataBound(object sender, GridViewRowEventArgs e)
{
  if (e.Row.RowType == DataControlRowType.DataRow)
 {
   // look for your control  here and disable it if needed
    LinkButton lnk= (LinkButton)e.Row.FindControl("HypUName");
    
     if(lnk != null)
     {
       // do your condition check here
        //if passes disable link 
       lnk.Enabled = false;
     }
  }
}
