问题描述
大家好,
我在Gridview的Rowdatabound事件中添加了一个新控件.下面是代码:
hi all,
I have added a new control in Rowdatabound event of Gridview .Below is the code:
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
DataRowView drv = (DataRowView)e.Row.DataItem;
if (drv != null)
{
Literal ltr = e.Row.FindControl("ltr") as Literal;
ltr.Text = drv.Row["Id"].ToString();
if (e.Row.RowIndex == 0)
{
TextBox oTB = new TextBox();
oTB.ID = "TextBox1";
e.Row.Cells[1].Controls.Add(oTB);
oTB = null;
}
if (e.Row.RowIndex == 1)
{
Panel p1 = new Panel();
p1.Width = Unit.Pixel(500);
p1.Height = Unit.Pixel(200);
p1.ScrollBars = ScrollBars.Vertical;
CheckBoxList cbl = new CheckBoxList();
cbl.ID = "cbl";
cbl.RepeatColumns = 2;
cbl.Items.Add(new ListItem("JAKARTA", "JKT"));
cbl.Items.Add(new ListItem("Maharashtra", "MH"));
p1.Controls.Add(cbl);
e.Row.Cells[1].Controls.Add(p1);
}
}
}
}
我在下面编写了用于访问控制的代码,但它始终为null,
I wrote below code to access control but it always give null,
foreach (GridViewRow row in GridView1.Rows)
{
TextBox txt = row.FindControl("TextBox1") as TextBox;
CheckBoxList cbl = row.FindControl("cbl") as CheckBoxList;
}
