Forms Data Controls :: Getting A Boolean Response From An Eval Operator?

Oct 18, 2010

I would like to use an eval stmt to return a true/false for the visible property of a HyperLinkField. IF clientComment exists, I would like it to return True, if clientComment is null or "", then would like it to return False.

By default I noticed it already will not show the hyperlink if clientComment is Null, however the bug I'm running into is if the client enters a comment but then later deletes it so it's not null but blank, or "", in which case the HyperLinkField will incorrectly display. Here's my attempt so far but I'm obviously hitting a wall:

Visible='<%# Eval("clientComment")==Null or =="",False) %>'

Pass Eval As Javascript Function Parameter In Gridview?

Jun 25, 2010

I have the following:

<asp:Button ID="wrqst_need_ind_btn" runat="server" Text = "Create WR"
CommandArgument='<%# Eval("dvc_nm") + "|" + Eval("data_orgtn_yr") %>'/>

I want to pass in as two additional params the Eval("dvc_nm") and Eval("data_orgtn_yr") to the popup function.


I tried by removing the single quotes from insode the <% %> tags. Which gave me this:

onClientClick='<%# "javascript:popUp(popup_createWR.aspx," + Eval("dvc_nm") + "," + Eval("data_orgtn_yr") + ")" %>'

which complied, but when I clicked the button I did not get a pop up, the page just posted back and reloaded and said errors on page, but no popup...

Create A Generic Util Function To Be Used In Eval Page?

Mar 16, 2010

I am currently binding a Nullable bit column to a listview control. When you declare a list view item I need to handle the case when the null value is used instead of just true or false.

<asp:Checkbox ID="Chk1" runat="server"
Checked='<%# HandleNullableBool(Eval("IsUsed")) %>' />

Then in the page I add a HandleNullableBool() function inside the ASPX page.

protected static bool HandleNullableBool(object value)
return (value == null) ? false : (bool)value;

This works fine but I need to use this in several pages so I tried creating a utility class with a static HandleNullableBool. But using it in the asp page does not work. Is there a way to do this in another class instead of the ASPX page?

<asp:Checkbox ID="Chk1" runat="server"
Checked='<%# Util.HandleNullableBool(Eval("IsUsed")) %>' />
