更改页脚下拉列表时Gridview结构出现故障
我有一个gridview，显示＆＃34;没有找到结果＆＃34;当空时，用页脚添加新行。这部分显示正常。
我已经为无结果实现了以下功能。
private void ShowNoResultFound(DataTable dt, GridView gv)
{
dt.Rows.Add(dt.NewRow()); // create a new blank row to the DataTable
// Bind the DataTable which contain a blank row to the GridView
gv.DataSource = dt;
gv.DataBind();
// Get the total number of columns in the GridView to know what the Column Span should be
int columnsCount = gv.Columns.Count;
gv.Rows[0].Cells.Clear();// clear all the cells in the row
gv.Rows[0].Cells.Add(new TableCell()); //add a new blank cell
gv.Rows[0].Cells[0].ColumnSpan = columnsCount; //set the column span to the new added cell
//You can set the styles here
gv.Rows[0].Cells[0].HorizontalAlign = HorizontalAlign.Center;
gv.Rows[0].Cells[0].ForeColor = System.Drawing.Color.Red;
gv.Rows[0].Cells[0].Font.Bold = true;
//set No Results found to the new added cell
gv.Rows[0].Cells[0].Text = "NO RESULT FOUND!";
}
当我更改下拉列表索引时，会触发下面的代码
protected void fddlItemDesc_SelectedIndexChanged(object sender, EventArgs e)
{
DropDownList fddlItem = (DropDownList)GVInvoiceDet.FooterRow.FindControl("fddlItemDesc");
TextBox hsnCode = (TextBox)GVInvoiceDet.FooterRow.FindControl("txtItemHSN");
HiddenField hdnFtItemGST = (HiddenField)GVInvoiceDet.FooterRow.FindControl("hdnFooterItemGST");
TextBox itemCode = (TextBox)GVInvoiceDet.FooterRow.FindControl("txtItemCode");
TextBox unitValue = (TextBox)GVInvoiceDet.FooterRow.FindControl("txtItemUnitValue");
TextBox unitRate = (TextBox)GVInvoiceDet.FooterRow.FindControl("txtItemUnitRate");
if (fddlItem.SelectedIndex == 0)
{
itemCode.Text = "";
hsnCode.Text = "";
hdnFtItemGST.Value = "";
unitRate.Text = "";
unitValue.Text = "";
}
else
{
hsnCode.Text = fddlItem.SelectedValue.Split('-')[1];
itemCode.Text = fddlItem.SelectedValue.Split('-')[0];
hdnFtItemGST.Value = fddlItem.SelectedValue.Split('-')[2];
unitRate.Text = fddlItem.SelectedValue.Split('-')[3];
unitValue.Text = unitRate.Text;
}
}
问题是第一排的colspan受到干扰。 Colspan位于第一个细胞中，但其他细胞也如图所示添加：
