使用C＃asp.net在gridview中创建超链接按钮单元格

Question

I am having a GridView in my web page. Which is displaying the data with the columns as Status, Name , Id and Action . My status column always filled with the 3 values( Complete, Queued and Failed ) randomly.

Now I want to display this status column values as a link ,If it is having the value either "Failed" or "Queued". But "Complete" status should not be display as a link.

How Can I achive this design during the runtime?

My Code for binding the data into the grid is,

protected void Page_Load(object sender, EventArgs e)
    {
        DataTable dtActionList = clsactionList.GetADActionList();
        grdADActionList.DataSource = dtActionList;
        grdADActionList.DataBind();
    }
    protected void grdADActionList_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        foreach (GridViewRow gvr in grdADActionList.Rows)
        {
            if ((gvr.FindControl("Label1") as Label).Text == "Completed")
            {
                (gvr.FindControl("Label1") as Label).Visible = true;
                (gvr.FindControl("HyperLink1") as HyperLink).Visible = false;
            }
        }
    }

using this code I am just simply binding the values in the grid. I am not able to create the Status column as having link buttons based on the binded values for that status column.

My .aspx Code is:

<asp:GridView ID="grdADActionList" runat="server" Height="83px" Width="935px" AutoGenerateColumns="false" OnRowDataBound="grdADActionList_RowDataBound">

     <Columns>
      <asp:TemplateField HeaderText="Status" SortExpression="Status">
            <ItemTemplate>
                 <asp:HyperLink ID="HyperLink1" runat="server" NavigateUrl='http://localhost:52807/Default.aspx?'><%# Eval("Status") %>
                 </asp:HyperLink>
                 <asp:Label ID="Label1" runat="server" Text="<%# Container.DataItem %>" Visible="False"></asp:Label>
            </ItemTemplate>
      </asp:TemplateField>
      <asp:BoundField DataField="GivenName" HeaderText="GivenName"/>

Please help me to do this further....

On GridViewDataBound event, just hide the link and display a simple label if the value is complete .
ASP.NET:

<asp:TemplateField HeaderText="Status" SortExpression="Status">
    <ItemTemplate>
        <asp:HyperLink ID="HyperLink1" runat="server" NavigateUrl='your_url'>
            <%# Eval("Status") %>
        </asp:HyperLink>
        <asp:Label ID="Label1" runat="server" Text="<%# Eval("Status") %>" Visible="False"></asp:Label>
    </ItemTemplate>
</asp:TemplateField>

C#:

protected void onGridViewDataBound()
{
    foreach(GridViewRow gvr in grd)
        if((gvr.FindControl("Label1") as Label).Text.ToLower() == "complete") // Updated Line
        {
            (gvr.FindControl("Label1") as Label).Visible = true;
            (gvr.FindControl("HyperLink1") as HyperLink).Visible = false;
        }
}

you have to work in design file means .aspx file you have to use and

<asp:GridView ID="GridView1" runat="server" EnableModelValidation="True">
   <asp:TemplateField HeaderText="Hyperlink">
<ItemTemplate>
    <asp:HyperLink ID="HyperLink1" runat="server" 
        NavigateUrl='<%# Eval("CODE", @"http://localhost/Test.aspx?code={0}") %>' 
        Text='link to code'>
    </asp:HyperLink>
</ItemTemplate>

You can place an handler on RowDataBound event

protected void gw_RowDataBound(object sender, GridViewRowEventArgs e)
{
    if (e.Row.RowType == DataControlRowType.DataRow)    
    {

        DataRowView v_DataRowView = (DataRowView)e.Row.DataItem;

        string NavigateUrl = <....place your link here with DataRowView info>

        e.Row.Attributes.Add("onclick", NavigateUrl);
    }
}

For now you have your columns auto generated, so first disable that feature. Then you need to define each column as a BoundField, and for the hypelink, taking into account your condition, the best way is to define template field:

<asp:GridView ID="grdADActionList" runat="server" BorderStyle="Double" BorderWidth="3px" 
               Height="83px" Width="935px"
               AutoGenerateColumns="false">
        <Columns>
            <asp:BoundField DataField="Name" HeaderText="Name"/>
            <asp:BoundField DataField="Action" HeaderText="Action"/>
            <asp:BoundField DataField="Id" HeaderText="Id"/>
            <asp:TemplateField HeaderText="Status">
                <ItemTemplate>
                    <asp:HyperLink runat="server" NavigateUrl="~/link/address" Text='<%# Eval("Status") %>'
                                   Visible='<%# (int)Eval("Status") != 1 %>'/>
                    <asp:Label runat="server" Text='<%# Eval("Status") %>'
                               Visible='<%# (int)Eval("Status") == 1 %>'>
                </ItemTemplate>
            </asp:TemplateField>
        </Columns>
</asp:GridView>

Note that this is just a variation - you have not specified what values does Status column contain, so I assumed this is int-based enumeration.
