Hi this is notorious.

I have a question that I am creating my own website just like yellow pages and I am facing a problem that there are few columns in rows in the database that are not have the values and I have taken few label in the grid view like comp name and mobile and phone are few common columns and I want to hide the labels whose binded data is not present in the database.

Can this be done in any possible means?

Solution 1

Using a GridView?

There are two properties of the columns:

ConvertEmptyStringToNull
NullDisplayText

Either or both might be of use to you.

If you are using TemplateFields, set the default text of the label to an empty string. (Not tested, but should do it.)

Solution 2

use to bind visibility like

<asp:Label Id="id" runat="server" Text="<%#Eval("fld")%>" Visible="<%#Eval("fld")!=DBNull.Value && !string.IsNullOrEmpty( Convert.ToString(Eval("fld"))) %>" />

<hr style="size:2; color:Blue;" /><br />
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Image">
<ItemTemplate>
&nbsp&nbsp&nbsp&nbsp    <asp:Image ID="Image1" runat="server" Visible="False" />&nbsp&nbsp&nbsp&nbsp
</ItemTemplate>
</asp:TemplateField>
</Columns>
<PagerStyle HorizontalAlign="Center" VerticalAlign="Top" />
<HeaderStyle ForeColor="White" Font-Bold="True"
Font-Names="Bookman Old Style" Font-Size="Large" Height="0px" />
</asp:GridView>

i think this better explian the situation in the above gridview i want that if there is no data present in the the email label which is bounded is aleready hidden but its cation label is present that should also get hidden.
