问题描述
我想在gridview中显示我通过使用datatable在文本框中输入的数据
我在源代码部分添加了以下内容
i want to display a data in gridview what i have enter in textboxes by using datatable
i have add the following in source part
<form id="form1" runat="server">
<div>
<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
<asp:TextBox ID="TextBox2" runat="server"></asp:TextBox>
<asp:TextBox ID="TextBox3" runat="server"></asp:TextBox>
<asp:Button ID="Button1" runat="server" onclick="Button1_Click"
style="height: 26px" Text="Button" />
<br />
<br />
<br />
<asp:GridView ID="GridView1" runat="server">
</asp:GridView>
<br />
</div>
</form>
在按钮中单击事件
我已经写了以下代码
in button click event
i have write the following code
{
DataTable dt = new DataTable();
DataRow dr;
dt.Columns.Add("Name");
dt.Columns.Add("Address");
dt.Columns.Add("Number");
//First fill all the date present in the grid
for(int intCnt=0;intCnt<gridview1.rows.count;intcnt++)>
{
if (GridView1.Rows[intCnt].RowType == DataControlRowType.DataRow)
{
dr = dt.NewRow();
dr["Name"] =GridView1.Rows[intCnt].Cells[0].Value;
dr["Address"] = GridView1.Rows[intCnt].Cells[1].Value;
dr["Number"] = GridView1.Rows[intCnt].Cells[2].Value;
dt.Rows.Add(dr);
}
}
dr = dt.NewRow();
dr["Name"] = TextBox1.Text;
dr["Address"] = TextBox2.Text;
dr["Number"] = TextBox3.Text;
dt.Rows.Add(dr);
Gridview1.DataSource = dt;
Gridview1.DataBind();
}
当我运行asp.net应用程序时
将会发生以下编译错误
when i run the asp.net application
the following compile error will occur
Compiler Error Message: CS1061: 'System.Web.UI.WebControls.TableCell' does not contain a definition for 'Value' and no extension method 'Value' accepting a first argument of type 'System.Web.UI.WebControls.TableCell' could be found (are you missing a using directive or an assembly reference?)
推荐答案
尝试一下,
Try this,
protected void Button1_Click(object sender, EventArgs e)
{
DataTable dt = null;
try
{
if (Session["dtItems"] != null)
{
dt = (DataTable)Session["dtItems"];
}
else
{
dt = new DataTable();
dt.Columns.Add("Quantity");
dt.Columns.Add("Rate_Unit");
dt.Columns.Add("Amount");
}
DataRow dataRow;
dataRow = dt.NewRow();
dataRow["Quantity"] = TextBox1.Text;
dataRow["Rate_Unit"] = TextBox2.Text;
dataRow["Amount"] = TextBox3.Text;
dt.Rows.Add(dataRow);
dt.AcceptChanges();
Session["dtItems"] = dt;
GridView1.DataSource = dt.DefaultView;
GridView1.DataBind();
}
catch (Exception ex)
{
}
}
