问题描述
我有一个有几行的数据列表,在数据列表的最后,我有Button'Btndetails'和Lable LblDetails'。重复列设置为3.每列都有按钮'Btndetails'。
点击此按钮我想向用户显示标签'LblDetails'。有用。但是标签
显示在用户必须滚动和阅读的数据列表的最后一列。我希望这个
标签显示在该按钮本身附近,在同一列上。该怎么办?
I have a datalist with several rows and at the end inside the datalist I have Button 'Btndetails' and a Lable LblDetails'. The repeat columns is set to 3. Each column has button 'Btndetails'.
On click of this button I want to show a Label 'LblDetails' to the user. It works. But the Label
is shown at the last column of the datalist for which the user has to scroll and read. I want this
Label to be shown near to that button itself, on the same column itself. How to do it?
<asp:DataList ID="DataList1" runat="server" BackColor="White" Width="220" BorderStyle="None" BorderWidth="2" OnItemCommand="dl_item_command" RepeatColumns="3" style=" border-top-style:groove; border-top-color:Lime; border-left-width:medium;" RepeatDirection="Horizontal" >
<asp:UpdatePanel ID="dd" runat="server" >
<ContentTemplate>
<asp:Button ID="AddToCart" runat = "server" Text='Add to Cart' BackColor="#cccccc" Width="100px" Style=" font-family:Arial" ForeColor="#333333" commandname="myevent">
</asp:Button>
<asp:Button ID="BtnDetails" runat = "server" Text='Details' BackColor="DarkSlateBlue" Width="100px" Style=" font-family:Arial" ForeColor="White" commandname="myeventDetails">
</asp:Button>
<asp:Label ID="Lbldetails" runat="server" Visible="false" Height="197" BackColor="Black" ForeColor="GhostWhite" style=" size:auto; overflow:auto; position:absolute; width:246px"> </asp:Label>
if (e.CommandName == "myeventDetails") // check commandname here
{
int index = e.Item.ItemIndex;
// Button dd = (Button)DataList1.Items[index].FindControl("BtnDetails");
Label lbl1 = (Label)DataList1.Items[index].FindControl("lblProductId");
v_code = Convert.ToInt32(lbl1.Text);
Label CategoryLbl = (Label)DataList1.Items[index].FindControl("CategoryLbl");
v_categoryid = Convert.ToInt32(CategoryLbl.Text);
SqlCommand cmd4 = new SqlCommand("SELECT DescriptionStatic from product WHERE CategoryId='" + v_categoryid + "' and ProductId='" + v_code + "'", con);
SqlParameter param4 = new SqlParameter();
param4.ParameterName = "@v_mem_id1";
param4.Value = "ss";
cmd4.Parameters.Add(param4);
con.Open();
SqlDataReader reader1 = cmd4.ExecuteReader();
if (reader1.HasRows)
{
while (reader1.Read())
{
string v_descriptionstatic = reader1.GetString(0);
Lbldetails.Text = Convert.ToString(v_descriptionstatic);
//Lbldetails.Style[HtmlTextWriterStyle.Top] = "610px";
Lbldetails.Visible = true;
