How can I open another page when pressing the Edit button on a gridview?

Question

I have a Gridview control in asp.net with C#.

In my application when I press the edit button from Gridview I need to open the information in another window. At this moment I use 'Response.Redirect("..")' but it opens in the same window.

I've tried:

 protected void OutputGridView_RowEditing(object sender, GridViewEditEventArgs e)
        {
            outputGridView.EditIndex = e.NewEditIndex;
            GridViewRow row = outputGridView.Rows[outputGridView.EditIndex];
           
            string url = "http://localhost/MyPage.aspx";
            Response.Write("<script>");
            Response.Write("window.open('" + url + "')");
            Response.Write("<" + "/script>")
 
            e.Cancel = true;
        }

But with no luck.

What's the best way to do this?

Answer 1

Instead of writing directly to the response stream try this:

Page.ClientScript.RegisterStartupScript(this.GetType(), "OpenNewWindow", "window.open(...)", true);

ASPX: Create a gridview like this

<asp:GridView runat="server" AllowPaging="True" AutoGenerateColumns="False" ID="gvSticker"
                                                        Width="100%" EmptyDataText="No sticker found for this Fisher. Click on add to Add a new sticker."
                                                        HorizontalAlign="Left" ShowFooter="True" ShowHeaderWhenEmpty="True" BackColor="White"

                                                        <SortedDescendingHeaderStyle BackColor="#00547E" />
                                                        </asp:GridView>    

In data bound event add the code.

 protected void gvSticker_RowDataBound(object sender, System.Web.UI.WebControls.GridViewRowEventArgs e)
        {
            if (Session["FisherId"] != null)
            {
                if (e.Row.RowType == DataControlRowType.DataRow)
                {
                    Label lblStatus = (Label)e.Row.FindControl("lblStickerStatus");


                    if (e.Row.RowIndex == 0)
                    {
                        if (lblStatus.Text.Contains("Active"))
                        {
                            btnAddSticker.Enabled = false;
                            HyperLink hlStickerNum = (HyperLink)e.Row.FindControl("hlStickerNumber");
                            if (!string.IsNullOrEmpty(hlStickerNum.Text.Trim()))
                            {

string urlWithParameters = "Stickers.aspx?StickerId=" + hlStickerNum.Text; hlStickerNum.Attributes.Add("OnClick", "popWinNote('" + urlWithParameters + "')");

                            }

                        }
                        else
                        {
                            btnAddSticker.Enabled = true;
                            btnVoidSticker.Enabled = true;
                        }

                    }
                }
            }
            else
            {
                btnAddSticker.Enabled = true;
                btnVoidSticker.Enabled = true;
            }
        }

And in aspx page add a function in script tag PopWinNote to open a show modal dialog if you need a small window. This code is not actually your required code but might give you idea regarding the implementation of logic

Answer 3

Try this

protected void OutputGridView_RowEditing(object sender, GridViewEditEventArgs e)
{
    try
    {
        outputGridView.EditIndex = e.NewEditIndex;
        GridViewRow row = outputGridView.Rows[outputGridView.EditIndex];

        string url = "http://localhost/MyPage.aspx";
        StringBuilder sb = new StringBuilder();
        sb.AppendLine("<script type='text/javascript'>");
        sb.AppendLine("window.open('" + url + "')");
        sb.AppendLine("<" + "/script>");
        ClientScript.RegisterStartupScript(this.GetType(), "myjs", sb.ToString(), false);
        //or if the gridview is inside an updatepanel do the code given below
        //ScriptManager.RegisterStartupScript(UpdatePanel1, UpdatePanel1.GetType(), "myjs", sb.ToString(), false);
    }
    catch (System.Threading.ThreadAbortException)
    {
        throw;
    }
    catch (Exception err)
    {
        //handle error here
        //Elmah.ErrorSignal.FromCurrentContext().Raise(err);
    }        
}

As I have commented in the code above, if you are using ScriptManager, uncomment and use this

ScriptManager.RegisterStartupScript(UpdatePanel1, UpdatePanel1.GetType(), "myjs", sb.ToString(), false);

I have tested it and its working.

Answer 4

This code will open the window in new window. for this you need to use the ScriptManager

string BrowserSettings = "status=no,toolbar=no,menubar=no,location=no,resizable=no,"+
                                        "titlebar=no, addressbar=no, width=600 ,height=750";
            string URL = "http://localhost/MyPage.aspx";
            string scriptText = "window.open('" + URL + "','_blank','" + BrowserSettings + "');";
            ScriptManager.RegisterClientScriptBlock(this, typeof(Page), "ClientScript1", scriptText, true);
