I click the link and btnNotes_Click fires but the row doesnt get selected, so I get a System.ArgumentOutOfRangeException on GridViewRow row = GVBugs.Rows[GVBugs.SelectedIndex];

protected void btnNotes_Click(object sender, EventArgs e)//EventArgs e)//object sender, GridViewCommandEventArgs e GridViewCommandEventArgs
{
GridViewRow row = GVBugs.Rows[GVBugs.SelectedIndex];
// DataRow[] row = GetDataRow(sender, e);

int IssueId = row.Cells[20].ToString().ToInt();// row[0][20].ToString().ToInt();

// DataRow[] row = GetDataRow(sender, e); // GV_Select(sender, e);

// int IssueId = row[0][20].ToString().ToInt();
Response.Redirect(String.Format("Notes.aspx?IssueId={0}", 3));//IssueId

}

<asp:GridView ID="GVBugs" runat="server"
DataKeyNames="IssueId"
AutoGenerateColumns="False"
OnSelectedIndexChanged="GvSelect"
OnRowCreated="GVBugs_OnRowCreated"
CssClass="gridView" GridLines="Vertical" Width="100%">
<Columns>
<asp:CommandField HeaderText="View" ShowSelectButton="True" SelectText="History" />
<asp:TemplateField HeaderText="View" ItemStyle-Width="75px" ItemStyle-HorizontalAlign="Center">
<ItemTemplate>
<asp:LinkButton Visible="true" ID="btnNotes" runat="server" CausesValidation="False" OnClick="btnNotes_Click"
Text="Notes" />
</ItemTemplate>
</asp:TemplateField>
<asp:CommandField HeaderText="Notes2" SelectText="Notes2" ShowSelectButton="True" />
<asp:BoundField DataField="AddDate" HeaderText="Added" SortExpression="AddDate" Visible="true" DataFormatString="{0:d}" />
</Columns>

Istead of use button click, you have to use GridView.RowCommand, so you can have multiple buttons each with a specific command name
Just in case for exisitng SelectButton command name is "Select"

Hi mikeasp30,

System.ArgumentOutOfRangeException

First of all, please make sure your Gridview GVBugs has at least 21 columns since you are trying to get the 21st cell.

int IssueId = row.Cells[20].ToString().ToInt();

I guess what you really want here is the text of the cell instead of the cell control itself, right?

I built a demo here, please check if it helps,

aspx:

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title></title>
</head>
<body>
    <form id="form1" runat="server">
        <div>
            <asp:GridView ID="GVBugs" runat="server"
                DataKeyNames="IssueId"
                AutoGenerateColumns="False"
                CssClass="gridView" GridLines="Vertical" Width="100%">
                <Columns>
                    <asp:CommandField HeaderText="View" ShowSelectButton="True" SelectText="History" />
                    <asp:TemplateField HeaderText="View" ItemStyle-Width="75px" ItemStyle-HorizontalAlign="Center">
                        <ItemTemplate>
                            <asp:LinkButton Visible="true" ID="btnNotes" runat="server" CausesValidation="False" OnClick="btnNotes_Click"
                                Text="Notes" />
                        </ItemTemplate>
                    </asp:TemplateField>
                    <asp:CommandField HeaderText="Notes2" SelectText="Notes2" ShowSelectButton="True" />
                    <asp:BoundField DataField="AddDate" HeaderText="Added" SortExpression="AddDate" Visible="true" DataFormatString="{0:d}" />
                </Columns>
                <EmptyDataTemplate>
                    No Data Found.
                </EmptyDataTemplate>
            </asp:GridView>
        </div>
    </form>
</body>
</html>

cs:

        protected void Page_Load(object sender, EventArgs e)
        {
            DataTable dt = new DataTable();
            dt.Columns.AddRange(new DataColumn[5] { new DataColumn("FirstName"), new DataColumn("LastName"), new DataColumn("IssueId"), new DataColumn("AddDate"), new DataColumn("username") });
            dt.Rows.Add("AA", "aa", "1", "1", "Aa");
            dt.Rows.Add("BB", "bb", "2", "2", "Bb");
            dt.Rows.Add("CC", "cc", "3", "3", "Cc");
            dt.Rows.Add("DD", "dd", "4", "4", "Dd");
            dt.Rows.Add("EE", "ee", "5", "5", "Ee");
            dt.Rows.Add("FF", "ff", "6", "6", "Ff");
            dt.Rows.Add("GG", "gg", "7", "7", "Gg");
            GVBugs.DataSource = dt;
            GVBugs.DataBind();
        }
        protected void btnNotes_Click(object sender, EventArgs e)
        {
            LinkButton lbt = (LinkButton)sender;
            GridViewRow row = (GridViewRow)lbt.NamingContainer;
            int IssueId = Convert.ToInt32(row.Cells[3].Text.ToString());
            Response.Write(String.Format("Notes.aspx?IssueId={0}", IssueId));
        }

result:

Best Regard,
