问题描述
我有一个GridView，并且GridView的标头字段是程序中ListBox中的项目.因此，每次运行时，生成的列数都是动态的.因此，基于此，如果我单击GridView内关联的编辑"按钮，如何为该行的每个单元格生成TextBox.
我编写的.cs代码是:
I have a GridView, and the header field of the GridView are the items from a ListBox in my program. Therefore the number of columns generated is dynamic every time I run. So based on this if I click on Edit button associated inside my GridView, how do I generate TextBox for each cell of that row.
The .cs code I have written is:
protected void DONE4_Click(object sender, EventArgs e)
{
Panel7.Visible = true;
SqlDataAdapter mydat = new SqlDataAdapter("SELECT DISTINCT Profile_Instance FROM Profile_Master", con);
DataSet dst = new DataSet();
mydat.Fill(dst, "Table");
ListBox3.Items.Clear();
ListBox3.DataSource = dst.Tables[0];
ListBox3.DataTextField = dst.Tables[0].Columns["Profile_Instance"].ColumnName;
ListBox3.DataBind();
int count = ListBox3.Items.Count;
DataTable dt = new DataTable();
DataRow rw = default(DataRow);
for (int i = 0; i < ListBox1.Items.Count; i++)
{
dt.Columns.Add(ListBox1.Items[i].ToString(),
System.Type.GetType("System.String"));
}
for (int j = 0; j < count; j++)
{
rw = dt.NewRow();
for (int i = 0; i < ListBox1.Items.Count; i++)
{
rw[ListBox1.Items[i].ToString()] = " ";
}
dt.Rows.Add(rw);
}
GridView2.DataSource = dt;
GridView2.DataBind();
foreach (GridViewRow grdRow in GridView2.Rows)
{
DropDownList bind_dropdownlist = new DropDownList(); // defining the property of the DropDownList as bind_dropdownlist
bind_dropdownlist = (DropDownList)(GridView2.Rows[grdRow.RowIndex].Cells[0].FindControl("Pro_List")); // finding the DropDownList from the gridiew for binding
SqlDataAdapter mydata = new SqlDataAdapter("SELECT DISTINCT Profile_Instance FROM Profile_Master", con);
DataSet dset = new DataSet(); // binding the DropDownList with the dataset ds
mydata.Fill(dset, "Table");
bind_dropdownlist.DataSource = dset;
bind_dropdownlist.DataTextField = "Profile_Instance"; // set the DropDownList's DataTextField as designation which display the designation in the dropdownlist after fetching the data from database
bind_dropdownlist.DataBind();
bind_dropdownlist.Items.Insert(0, new ListItem("---Choose Profile---", "-1"));
}
}
GridView的设计代码为:
The design code for the GridView is:
<pre lang="HTML"><asp:Panel ID="Panel7" runat="server">
<asp:GridView ID="GridView2" runat="server" CellPadding="4"
style="text-align: center; font-size: small" BackColor="White"
BorderColor="#CC9966" BorderStyle="None" BorderWidth="1px">
<Columns>
<asp:TemplateField HeaderText="">
<ItemTemplate>
<asp:DropDownList ID="Pro_List" runat="server">
<asp:ListItem>--Select--</asp:ListItem>
</asp:DropDownList>
</ItemTemplate>
</asp:TemplateField>
<asp:CommandField ShowEditButton="True" />
</Columns>
</asp:GridView>
</asp:Panel>
有人可以帮我吗?我希望问题清楚.
Can someone please help me on this? I hope the question is clear.

我认为您正在使用基于Ado.net连接的程序
尝试这样
i think you are using Ado.net connectivity based program
try like this
