事件是
protected void btnAdd_Click(object sender, EventArgs e)
{
pnlAddFilter.Style.Add("display", "block");
//pnlAddFilter.Visible = true;
DataTable dtFilter = new DataTable();
dtFilter.Columns.Add("FOId");
dtFilter.Columns.Add("Filtername");
dtFilter.Columns.Add("FilterOption");
DataRow drFilter;
if (Session["Filter"] != null)
{
dtFilter = (DataTable)Session["Filter"];
}
drFilter = dtFilter.NewRow();
drFilter["FOId"] = drpFilterOption.SelectedValue;
drFilter["Filtername"] = drpFilter.SelectedItem.Text;
drFilter["FilterOption"] = drpFilterOption.SelectedItem.Text;
dtFilter.Rows.Add(drFilter);
Session["Filter"] = dtFilter;
btnAdd.Enabled = false;
if (Session["Filter"] == null)
{
// pnlAddFilter.Visible = false;
pnlAddFilter.Style.Add("display", "none");
}
else
{
pnlAddFilter.Style.Add("display", "block");
// pnlAddFilter.Visible = true;
}
lblSuccess.Visible = true;
lblSuccess.Text = AppHardcodeValue.strAddFilterProduct;
}
答案 0 :(得分：0)
根据我的经验，模态弹出窗口不能很好地支持动态渲染数据。我想你可能需要将你的模态内容放在更新面板中，以便能够使用服务器端代码来更新标签。
