Add LinkButton to gridview subtotal row

Question

I am trying to add linkbutton with URL to gridview subtotal row. I'm using the below code and not able to add URL.

Can anyone please provide suggestions on how this can be handled?

Update 1:

    private void AddTotalRow(string labelText, string value)
    {
        GridViewRow row = new GridViewRow(0, 0, DataControlRowType.DataRow, DataControlRowState.Normal);
        row.BackColor = ColorTranslator.FromHtml("#F9F9F9");
        row.Cells.AddRange(new TableCell[3] { new TableCell{ Text = labelText, HorizontalAlign = HorizontalAlign.Right },
     new TableCell{ Text = value, HorizontalAlign = HorizontalAlign.Right },
     HyperLinkCell(value, "http://www.google.com") });
    }

    protected  TableCell HyperLinkCell(string text, string url)
    {
        TableCell cell = new TableCell();
        HyperLink link = new HyperLink();
        try
        {
            link.Text = text;
            link.Font.Underline = true;
            link.Target = "_blank";
            link.NavigateUrl = url;
            link.Attributes.Add("style", "color:Black;");
            cell.Controls.Add(link);
        }
        catch (Exception ex)
        {
            throw ex;
        }
        return cell;
    }

you have `string value` and you are passing it to `AddHyperLink` method. but `AddHyperLink` method has `TableCell` as first argument. So you can not pass string instead of TableCell there. That's why you are seeing this error. — Chetan, May 10 '18 at 10:27
@ChetanRanpariya - Updated my post. Can you please look into it. Not able to pass URL. — Learner, May 10 '18 at 10:31
While creating new LinkButton you are setting `Text = AddHyperLink`. AddHyperLink method returns HyperLink object which obviously you can not assign to Text coz it is a string type. — Chetan, May 10 '18 at 10:32
You need to go back to the basic and understand the datatypes, assignments and error messages. Also you need to share your code in the question instead of image. we can not copy paste your code from image. — Chetan, May 10 '18 at 10:35

You want to add new cells to the table. But you are also trying to add LinkButton to the TableCell collection.

Also While creating new LinkButton you are setting Text = AddHyperLink. AddHyperLink method returns HyperLink object which obviously you can not assign to Text coz it is a string type.

Also you can not add LinkButton to the TableCell collection.

You need to change your code as following.

private void AddTotalRow(string labelText, string value)
{
     GridViewRow row = new GridViewRow(0,0, DataControlwRowType.DataRow, DataControlRowState.Normal);
     row.BackColor = ColorTranslator.FromHtml("#F9F9F9");
     row.Cells.AddRange(new TableCell[4] { new TableCell(),
         new TableCell{ Text = labelText, HorizontalAlign = HorizontalAlign.Right }.
         new TableCell{ Text = value, HorizontalAlign = HorizontalAlign.Right),
         //Calling HyperLinkCell method which will return a TableCell with HyperLink in it.
         HyperLinkCell(value, "http://www.google.com")
        });

    gvData.Rows.Add(row);
 }

 protected TableCell (string text, string url)
 {
     //Create new Cell
     TableCell cell = new TableCell();
    //Create new HyperLink.
     HyperLink link = new HyperLink();
     try
     {
         link.Text = text;
         link.Font.UnderLine = true;
         link.Target = "_blank";
         link.NavigationUrl = url;
         link.Attributes.Add("style", "color:Black;");
         //Add hyperlink to the cell.
         cell.Controls.Add(link);
     }
     catch(Exception ex)
     {
     }
     //Return Cell with HyperLink.
     return cell;
 }

This would resolve the error as well as give you proper way to add cell with hyperlink in the gridviewrow.

Are you getting any errors now? I updated my answer, please check now — Chetan, May 10 '18 at 11:44
I 'm getting error in this line `gvData.Rows.Add(row);`. It says GridViewRowCollection does not contain a definition for add. — Learner, May 10 '18 at 11:59
You can not add new row to GridView this way. You need to ask different question for that with proper details of what exactly you want to do. https://stackoverflow.com/questions/19485909/add-new-row-in-gridview-after-binding-c-asp-net — Chetan, May 10 '18 at 12:24

try the below:

protected HyperLink AddHyperLink(string cell, string strURL)
{
    HyperLink h1 = new HyperLink();
    TableCell cells = new TableCell();
    try
    {
        h1.Text = cell;
        h1.Font.Underline = true;
        h1.Target = "_blank";
        h1.NavigateUrl = strURL;
        h1.Attributes.Add("style", "color:black");
        cells.Controls.Add(h1);

    }
    catch(Exception ex)
    {

    }
    return h1;
}

Updated my post. Can you please look into it. Not able to pass URL. – Learner May 10 '18 at 10:32
Now your second parameter is of type Hyperlink but you are passing a string. hence the error. you need to pass the same type variables as defined in the function declaration. – Gagan Deep May 10 '18 at 10:33
i have updated the answer.keep your AddTotalRow as it is. replace the AddHyperLink method. – Gagan Deep May 10 '18 at 10:39
It says cannot implicitly convert type 'HyperLink' to string. updated my post. – Learner May 10 '18 at 10:42
both parameters are string now. – Gagan Deep May 10 '18 at 10:44
This method returns HyperLink and OP is trying to assign outcome of this method to Text property of LinkButton. This will not resolve the error. – Chetan May 10 '18 at 10:49
