If there is no value in the database, I would like to hide my hyperlink within a gridview. Here's what I have:
visible='<%# Eval("my_field").Is Not Null %>'
Of course the Is Not Null doesnt work, is there something I can do to check:
1) if not null then set visible true
2) if null then set visible to false

I have a DataGridView with a ItemTeplate column, which has a HTML hyperlink (<a href....>) inside. When a user clicks on a link, a popup with a TextBox is showed to the user. Then the user can type a data. With this data, I must update the hyperlink's text in which the user clicked. All using javascript. The problem is that I don't know how to find the Hyperlink because there will be so many hyperlinks as rows in the DataGridView and they will have the same Id.
How can i find the hyperlink using javascript?

I have a Repeater displaying some data that doesn't do what I'd like to see. If a certain condition is met (ex: parent.NumOfChildren > 0) I would like a hyperlink shown. Here is what I have so far:
<asp:Repeater ID="parents" runat="server" >
<ItemTemplate>
<asp:HyperLink NavigateUrl='<%# "Children.aspx?parent=" + DataBinder.Eval(Container.DataItem,"Parent_ID")%>'
Text='View Children' runat="server" target="_self" ID="Hyperlink2" NAME="Hyperlink2"/> -
</ItemTemplate>
</asp:Repeater>
In this case, the "View Children" link shows up for every item in my Repeater, but I'd like it shown only if parent.GetNumOfChildren() > 0. Would it be correct to try setting the Visible="true/false" property of the HyperLink? Is that the norm for this sort of problem? Or, is there a way to wrap the entire <asp:Hyperlink> ... </asp:Hyperlink> tag in an if statement that has a reference to the object that is currently being interated in the Repeater? Ie:
if(CurrentDataItemInIteration.GetNumOfChildren() > 0)
{
<asp:Hyperlink> ..... </asp:Hyperlink>
}
To me, the Visible="true/false" solution seems cleaner, if possible.

using a repeater to display multiple 'comments' related to a parent database entity (a 'task' in my case). When the user creates these comments they can optionally attach a file. Now, I'm working on the page that lists these comments and I'm not sure how to go about displaying the link to the attached file, if one is present. There may not be a file. The database record that contains the comment will also contain the url to the file if one was attached.
what are my options for this? I would like to just display a link to the file after the comment content, only if a file is available.

how to bind data in an ItemTemplate column in my Gridview.
I have created an ObjectDatasource on my page bound to my Gridview using a Dataset from my linked SQL tables (PKs, FKs,etc...).
I am showing all my USERS table data in my Gridview but there are some columns which are ID's being displayed such as MembershipID, UserTypeID. These ID's are my foreign keys to other SQL tables.
I have easily been able to go into my EditTemplate for these columns, attach a new ObjectDataSource as a Lookup table, add a new DropDownList in place of the TextBox and then set Two-way binding so that the MembershipName & UserTypeName's are displayed for editing.
However, I cannot seem to work out how to do this Binding to the other ObjectDataSources in the ItemTemplate Label. Again i can make it work witha DDL, but i don't want any selections when just displaying the data in the Grid. I simply want the name to be shown in a label, but cannot work out the binding lookup?

What I have is a GridView with a DropDownList in an ItemTemplate (not an EditItemTemplate). My datasource is not a control, rather in the code-behind.
[Code]....
My main problem is that VS is not seeing that I have the dropdownlist, meaning I can not access any of the events in the code-behind. What I want to do is, when the value of the DropDownList is changed (SelectedIndexChanged), I want to grab the value of the RowIndex of the GridView.

I have a gridview, in which one of the columns [unitid] is a link that opens up other gridviews. When the [downtime] column is equal to '0', i'd like the link in [unitid] to be removed, and just show that field as text. Here's my code for the gridview:
<asp:GridView ID="gvUnitSummary" runat="server" AutoGenerateColumns="False"
CellPadding="4" ForeColor="#333333" HorizontalAlign="Center" Width="100%"
Font-Size="Medium" DataSourceID="sdsUnitSummary" DataKeyNames="unitid" EnableModelValidation="True"
EnableViewState="False" >
<AlternatingRowStyle BackColor="#CDDBB4" />
[Code] .....

I was wondering if anyone could help me. I have a template field which has four itemtemplates that each hold a label in a gridview. These labels are always constant with the same strings. What I want to do is change the css formatting of these four labels depending on the value of a column. So the css formatting would have to be done for each row, not the whole column. I bind the gridview to a dataaccesslayer so there is no sqldatasource on the page. Does anyone have any idea how to do this and where it would be done. I will have the dataview with the data sorted in the correct order. The actual column that is used to alter the CSS will not be in the gridview although I could assign it to the datakeyname if that makes it easier as the data is not sensitive.

So I have an <asp:Gridview> and in my C# file, I am setting the datasource to some database table, and doing .DataBind().
However, I want to hide a column in the table based on a Boolean variable.
Something like this:
gridview.Columns['Field5'].Visible = false;
Or perhaps:
int c = gridview.Rows.Count();
for(int i = 0; i < c; i++){
gridview.Rows['Field5'].Remove();
}
Perhaps I cannot make it invisible, but I'm sure I can at least loop through and remove all rows related to the column "field5". I don't know how to go about doing this.
Does anyone perhaps have a proper link to using the GridView Class and how all the methods are suppose to be used because it's not clear, perhaps not written by microsoft?
the internet seems to lack a lot of C# documentation (or maybe it's just cluttered with too much useless ASP.net information).
