问题描述
嗨
我已通过网格视图中的项目模板添加了复选框列,并希望在文本框中查看所选行的值
Hi
I have added the checkbox column through item template in grid view and want to see the value of selected row in the text box
public partial class Default3 : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
DataTable dt = new DataTable();
//dt.Columns.Add(new DataColumn("select", typeof(bool)));
dt.Columns.Add("Roll no");
dt.Columns.Add("Name");
dt.Columns.Add("marks");
dt.Rows.Add("D001", "Aditya", "80");
dt.Rows.Add("D002", "Arun", "75");
dt.Rows.Add("Doo3", "Nikhil", "85");
dt.Rows.Add("Doo3", "Nikhil", "85");
dt.Rows.Add("Doo3", "Nikhil", "85");
gvnew.DataSource = dt;
gvnew.DataBind();
}
protected void Button1_Click(object sender, EventArgs e)
{
GridViewRow row = gvnew.SelectedRow;
row.Cells[4].Text = TextBox2.Text;
row.Cells[5].Text = TextBox3.Text;
}
protected void gvnew_SelectedIndexChanged(object sender, EventArgs e)
{
GridViewRow row = gvnew.SelectedRow;
TextBox1.Text= row.Cells[3].Text;
TextBox2.Text= row.Cells[4].Text;
TextBox3.Text = row.Cells[5].Text;
TextBox1.ReadOnly = true;
}
protected void CheckBox1_CheckedChanged(object sender, EventArgs e)
{
foreach (GridViewRow row in gvnew.Rows)
{
CheckBox chk = (CheckBox)row.FindControl("chkbselect");
if (chk!=null && chk.Checked)
{
TextBox1.Text = gvnew.DataKeys[row.RowIndex].Value.ToString();
TextBox2.Text = gvnew.Rows[0].Cells[0].Text.ToString();
TextBox3.Text = row.Cells[5].Text;
TextBox1.ReadOnly = true;
//Response.Write("you have selected "+ gvnew.DataKeys[row.RowIndex].Value +"<br />");
}
}
}
}
推荐答案
<asp:gridview id="gvnew" runat="server" cellpadding="4" forecolor="#333333" gridlines="None" onselectedindexchanged="gvnew_SelectedIndexChanged" xmlns:asp="#unknown"> <asp:templatefield>
///在这里使用itemtemplate
///use itemtemplate here
<itemtemplate>
<asp:checkbox id="CheckBox1" runat="server" /> <asp:checkbox id="chkbselect" runat="server" oncheckedchanged="CheckBox1_CheckedChanged" />
<pagerstyle backcolor="#2461BF" forecolor="White" horizontalalign="Center" /> <asp:checkbox id="Chkbselect" runat="server" checked="True" />
并使用C#代码
and in c# code
TextBox2.Text = gvnew.Rows[0].Cells[0].Text.ToString();// changed here
Textbox txt=(TextBox)row.findcontrol("textboxid");
而不是文本框只读,您可以在客户端使用
onkeypress="javascript: return false;"
在文本框上.
试试吧
请投票对您有帮助
and rather than textbox readonly you can use on client side
onkeypress="javascript: return false;"
on textbox.
try it
