解决方案看来你正试图获得5个项目进行收集与5个项目。看着你code，看来你开始你的集合中的第二个值的位置是1集是从零开始，所以你应该索引为0的项目开始试试这个：
文本框BOX1 =（文本框）Gridview1.Rows [I] .Cells [0] .FindControl（txt_type）;
文本框BOX2 =（文本框）Gridview1.Rows [I] .Cells [1] .FindControl（txt_total）;
文本框BOX3 =（文本框）Gridview1.Rows [I] .Cells [2] .FindControl（txt_max）;
文本框box4 =（文本框）Gridview1.Rows [I] .Cells [3] .FindControl（txt_min）;
文本框box5 =（文本框）Gridview1.Rows [I] .Cells [4] .FindControl（txt_rate）;I'm adding dynamic Rows in ASP.Net GridView Control with TextBoxes. But I'm getting the error below when I click on my Add New Row button.
Specified argument was out of the range of valid values. Parameter name: index
What could be the error ?
Th code in my .aspx file
<div id="Div1" class="divTable"> <asp:gridview id="Gridview1" runat="server" autogeneratecolumns="false" gridlines="None" width="100%" height="100%"> <Columns> <asp:TemplateField> <ItemTemplate> <div class="divRow"> <div class="divColumn"> <div> <asp:Label ID="lbl1" runat="server" Text="Type Name" CssClass="formLable"></asp:Label> </div> <div> <asp:TextBox ID="txt_type" Width="200" runat="server" CssClass="txtbox"></asp:TextBox> </div> <span> <asp:RequiredFieldValidator ID="TYPE_NAME_VAL" runat="server" ControlToValidate="txt_type" ErrorMessage="Type is required."

if (ViewState["CurrentTable"] != null) { DataTable dtCurrentTable = (DataTable)ViewState["CurrentTable"]; DataRow drCurrentRow = null; if (dtCurrentTable.Rows.Count > 0) { for (int i = 1; i <= dtCurrentTable.Rows.Count; i++) { //extract the TextBox values TextBox box1 = (TextBox)Gridview1.Rows[rowIndex].Cells[1].FindControl("txt_type"); TextBox box2 = (TextBox)Gridview1.Rows[rowIndex].Cells[2].FindControl("txt_total"); TextBox box3 = (TextBox)Gridview1.Rows[rowIndex].Cells[3].FindControl("txt_max"); TextBox box4 = (TextBox)Gridview1.Rows[rowIndex].Cells[4].FindControl("txt_min"); TextBox box5 = (TextBox)Gridview1.Rows[rowIndex].Cells[5].FindControl("txt_rate"); drCurrentRow = dtCurrentTable.NewRow(); dtCurrentTable.Rows[i - 1]["Column1"] = box1.Text; dtCurrentTable.Rows[i - 1]["Column2"] = box2.Text; dtCurrentTable.Rows[i - 1]["Column3"] = box3.Text; dtCurrentTable.Rows[i - 1]["Column4"] = box4.Text; dtCurrentTable.Rows[i - 1]["Column5"] = box5.Text; rowIndex++; } dtCurrentTable.Rows.Add(drCurrentRow); ViewState["CurrentTable"] = dtCurrentTable; Gridview1.DataSource = dtCurrentTable; Gridview1.DataBind(); } } else { Response.Write("ViewState is null"); }
解决方案It seems that you are trying to get 5 items out of a collection with 5 items. Looking at your code, it seems you're starting at the second value in your collection at position 1. Collections are zero-based, so you should start with the item at index 0. Try this:
TextBox box1 = (TextBox)Gridview1.Rows[i].Cells[0].FindControl("txt_type"); TextBox box2 = (TextBox)Gridview1.Rows[i].Cells[1].FindControl("txt_total"); TextBox box3 = (TextBox)Gridview1.Rows[i].Cells[2].FindControl("txt_max"); TextBox box4 = (TextBox)Gridview1.Rows[i].Cells[3].FindControl("txt_min"); TextBox box5 = (TextBox)Gridview1.Rows[i].Cells[4].FindControl("txt_rate");
