如何在Asp.Net C＃中的網格視圖的第一行上顯示文本框
[英]How to Display Text Boxes on to the first row of Grid View in Asp.Net C#
問題描述
我想知道如何在網格視圖的頂部顯示文本框。
就像所附的圖片一樣
當我插入/更新/刪除記錄時，它會保留頂部的位置。
我對此一無所知，任何人都可以幫助我。
因為只有1到10條記錄是沒有問題的，
超過10條記錄意味着我需要翻頁，
它更難使用，所以我問。

希望看到您為相同，簡單的方法創建的代碼是編輯每一行，這對於初學者來說更容易
ASPX將是
<html xmlns="http://www.w3.org/1999/xhtml">
<head id="Head1" runat="server">
<title>GridView Crud (Select Insert Edit Update Delete) Operations using Single Stored Procedure in ASP.Net</title>
<style type="text/css">
.GridviewDiv {font-size: 100%; font-family: 'Lucida Grande', 'Lucida Sans Unicode', Verdana, Arial, Helevetica, sans-serif; color: #303933;}
.headerstyle
{
color:#FFFFFF;border-right-color:#abb079;border-bottom-color:#abb079;background-color: #df5015;padding:0.5em 0.5em 0.5em 0.5em;text-align:center;
}
</style>
</head>
<body>
<form id="form1" runat="server">
<div class="GridviewDiv">
<asp:GridView runat="server" ID="gvDetails" ShowFooter="true" AllowPaging="true" PageSize="10" AutoGenerateColumns="false" DataKeyNames="productid,productname" OnPageIndexChanging="gvDetails_PageIndexChanging" OnRowCancelingEdit="gvDetails_RowCancelingEdit"
OnRowEditing="gvDetails_RowEditing" OnRowUpdating="gvDetails_RowUpdating" OnRowDeleting="gvDetails_RowDeleting" OnRowCommand ="gvDetails_RowCommand" >
<HeaderStyle CssClass="headerstyle" />
<Columns>
<asp:BoundField DataField="productid" HeaderText="Product Id" ReadOnly="true" />
<asp:TemplateField HeaderText="Product Name">
<ItemTemplate>
<asp:Label ID="lblProductname" runat="server" Text='<%# Eval("productname")%>'/>
</ItemTemplate>
<EditItemTemplate>
<asp:TextBox ID="txtProductname" runat="server" Text='<%# Eval("productname")%>'/>
</EditItemTemplate>
<FooterTemplate>
<asp:TextBox ID="txtpname" runat="server" />
</FooterTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText = "Price">
<ItemTemplate>
<asp:Label ID="lblPrice" runat="server" Text='<%# Eval("price")%>'></asp:Label>
</ItemTemplate>
<EditItemTemplate>
<asp:TextBox ID="txtProductprice" runat="server" Text='<%# Eval("price")%>'/>
</EditItemTemplate>
<FooterTemplate>
<asp:TextBox ID="txtprice" runat="server" />
<asp:Button ID="btnAdd" CommandName="AddNew" runat="server" Text="Add" />
</FooterTemplate>
</asp:TemplateField>
<asp:CommandField ShowEditButton="True" ShowDeleteButton="true" />
</Columns>
</asp:GridView>
<asp:Label ID="lblresult" runat="server"></asp:Label>
</div>
</form>
</body>
</html>
您的代碼將是
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
BindGridview();
}
}
protected void BindGridview()
{
DataSet ds = new DataSet();
using (SqlConnection con = new SqlConnection("Data Source=Suresh;Integrated Security=true;Initial Catalog=MySampleDB"))
{
con.Open();
SqlCommand cmd = new SqlCommand("crudoperations", con);
cmd.CommandType= CommandType.StoredProcedure;
cmd.Parameters.AddWithValue("@status","SELECT");
SqlDataAdapter da = new SqlDataAdapter(cmd);
da.Fill(ds);
con.Close();
if (ds.Tables[0].Rows.Count > 0)
{
gvDetails.DataSource = ds;
gvDetails.DataBind();
}
else {
ds.Tables[0].Rows.Add(ds.Tables[0].NewRow());
gvDetails.DataSource = ds;
gvDetails.DataBind();
int columncount = gvDetails.Rows[0].Cells.Count;
gvDetails.Rows[0].Cells.Clear();
gvDetails.Rows[0].Cells.Add(new TableCell());
gvDetails.Rows[0].Cells[0].ColumnSpan = columncount;
gvDetails.Rows[0].Cells[0].Text = "No Records Found";
}
}
}
protected void gvDetails_RowCommand(object sender, GridViewCommandEventArgs e)
{
if (e.CommandName.Equals("AddNew"))
{
TextBox txtname = (TextBox)gvDetails.FooterRow.FindControl("txtpname");
TextBox txtprice = (TextBox)gvDetails.FooterRow.FindControl("txtprice");
crudoperations("INSERT", txtname.Text, txtprice.Text, 0);
}
}
protected void gvDetails_RowEditing(object sender, GridViewEditEventArgs e)
{
gvDetails.EditIndex = e.NewEditIndex;
BindGridview();
}
protected void gvDetails_RowCancelingEdit(object sender, GridViewCancelEditEventArgs e)
{
gvDetails.EditIndex = -1;
BindGridview();
}
protected void gvDetails_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
gvDetails.PageIndex = e.NewPageIndex;
BindGridview();
}
protected void gvDetails_RowUpdating(object sender, GridViewUpdateEventArgs e)
{
int productid = Convert.ToInt32(gvDetails.DataKeys[e.RowIndex].Values["productid"].ToString());
TextBox txtname = (TextBox)gvDetails.Rows[e.RowIndex].FindControl("txtProductname");
TextBox txtprice = (TextBox)gvDetails.Rows[e.RowIndex].FindControl("txtProductprice");
crudoperations("UPDATE",txtname.Text,txtprice.Text,productid);
}
protected void gvDetails_RowDeleting(object sender, GridViewDeleteEventArgs e)
{
int productid = Convert.ToInt32(gvDetails.DataKeys[e.RowIndex].Values["productid"].ToString());
string productname = gvDetails.DataKeys[e.RowIndex].Values["productname"].ToString();
crudoperations("DELETE",productname,"",productid);
}
protected void crudoperations(string status, string productname, string price, int productid)
{
using (SqlConnection con = new SqlConnection("Data Source=Suresh;Integrated Security=true;Initial Catalog=MySampleDB"))
{
con.Open();
SqlCommand cmd = new SqlCommand("crudoperations", con);
cmd.CommandType= CommandType.StoredProcedure;
if(status=="INSERT")
{
cmd.Parameters.AddWithValue("@status",status);
cmd.Parameters.AddWithValue("@productname",productname);
cmd.Parameters.AddWithValue("@price",price);
}
else if(status=="UPDATE")
{
cmd.Parameters.AddWithValue("@status",status);
cmd.Parameters.AddWithValue("@productname",productname);
cmd.Parameters.AddWithValue("@price",price);
cmd.Parameters.AddWithValue("@productid",productid);
}
else if(status=="DELETE")
{
cmd.Parameters.AddWithValue("@status",status);
cmd.Parameters.AddWithValue("@productid",productid);
}
cmd.ExecuteNonQuery();
lblresult.ForeColor = Color.Green;
lblresult.Text = productname+" details "+status.ToLower()+"d successfully";
gvDetails.EditIndex = -1;
BindGridview();
}
}
