Hi wonjartran,
You can add LinkButton Attributes["onclick"] on GridView1_RowDataBound method. The following code for your reference.
HTML:
<html xmlns="http://www.w3.org/1999/xhtml"> <head runat="server"> <title></title> </head> <body> <form id="form1" runat="server"> <div> <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="false" OnRowCommand="GridView1_RowCommand" OnRowDataBound="GridView1_RowDataBound"> <Columns> <asp:BoundField DataField="ID" HeaderText="ID" /> <asp:BoundField DataField="Product" HeaderText="Product" /> <asp:BoundField DataField="Version" HeaderText="Version" /> <asp:BoundField DataField="Description" HeaderText="Description" /> <asp:TemplateField> <ItemTemplate> <asp:LinkButton ID="CSDelete" runat="server" CommandName="CustomDelete" Text="Delete"></asp:LinkButton> </ItemTemplate> </asp:TemplateField> </Columns> </asp:GridView> </div> </form> </body> </html>ASPX.CS:
protected void Page_Load(object sender, EventArgs e) { if(!IsPostBack ) { bind(); } } private void bind() { DataTable tblDatas = new DataTable("Datas"); DataColumn dc = null; dc = tblDatas.Columns.Add("ID", Type.GetType("System.Int32")); dc.AutoIncrement = true;// dc.AutoIncrementSeed = 1;// dc.AutoIncrementStep = 1;// dc.AllowDBNull = false; dc = tblDatas.Columns.Add("Product", Type.GetType("System.String")); dc = tblDatas.Columns.Add("Version", Type.GetType("System.String")); dc = tblDatas.Columns.Add("Description", Type.GetType("System.String")); DataRow newRow; for (int i = 0; i < 5; i++) { newRow = tblDatas.NewRow(); newRow["Product"] = "Count" + i.ToString(); newRow["Version"] = "2.0"; newRow["Description"] = "Hello boy"; tblDatas.Rows.Add(newRow); } ViewState["dt"] = tblDatas; GridView1.DataSource = tblDatas; GridView1.DataBind(); } protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e) { if (e.Row.RowType == DataControlRowType.DataRow) { string item = e.Row.Cells[0].Text; foreach (LinkButton button in e.Row.Cells[4].Controls.OfType<LinkButton>()) { if (button.CommandName == "CustomDelete") { button.Attributes["onclick"] = "if(!confirm('Are you sure you want to delete: " + item + "?')){ return false; };"; } } } } protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e) { if (e.CommandName.Equals("CustomDelete")) { GridViewRow oItem = (GridViewRow)((LinkButton)e.CommandSource).NamingContainer; int RowIndex = oItem.RowIndex; Response.Write(oItem.Cells[0].Text+""+ oItem.Cells[1].Text); } }
