如何通过页面内部加载背后的代码在gridview中隐藏超链接控件？

Question

I have a gridview on my web form. I have taken a hyperlink control inside the template field of gridview. I want that this hyperlink should be visible to only site admin. I have done this through Gridview_RowDataBound property. But instead of doing this I want to hide this hyperlink within page load.

This is what I have done so far.

aspx page-

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" DataKeyNames="id" onrowdatabound="GridView1_RowDataBound1"
BorderStyle="None" EnableModelValidation="True" ShowHeader="False" Width="1000px" GridLines="None">
<Columns>
<asp:TemplateField>
                <ItemTemplate>
<asp:HyperLink ID="HyperLink2" runat="server" Font-Bold="True" Font-Size="Small" 
                        ForeColor="#FF3300" CommandName="EDT" CommandArgument="<%# ((GridViewRow) Container).RowIndex %>"
                        NavigateUrl='<%# Eval("id","test1.aspx?id={0}") %>'>HyLink</asp:HyperLink>
</ItemTemplate>
            </asp:TemplateField>

</Columns>
</asp:GridView>

cs page-

protected void GridView1_RowDataBound1(object sender, GridViewRowEventArgs e)
    {
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
            if (Convert.ToString(Session["logname"]) != "Admin")
            {
                HyperLink Hlnk = e.Row.FindControl("HyperLink2") as HyperLink;
                Hlnk.Visible = false;
            }
        }
    }

How can I do this within page load? Please guide.

Answer 1

try this:

foreach(GridViewRow row in GridView1.Rows) {
    if(row.RowType == DataControlRowType.DataRow) {
        HyperLink myHyperLink = row.FindControl("HyperLink2") as HyperLink;
        myHyperLink.Visible = false;
    }
}

or:

for (int i = 0; i < GridView1.Rows.Count; i++)
 {
  HyperLink myHyperLink = (HyperLink)gvExcParts.Rows[i].FindControl("HyperLink2");
  myHyperLink.Visible = false;
 }

but make sure bind data to gride view then find controls inside it, otherwise this will not work.

在将DataBind转换为GridView之后再尝试...

GridView1.Columns[3].Visible = false;
