Forms Data Controls :: Skip Link In Databinding On An Empty Image?
Sep 18, 2010
I have a problem with databinding an <a href> link when there's no image available for the link.My intention is to display a link with <a href=...> when there is an image available and skip the <a href...> if there is no image available but just display the image.i've tried the following but no result:
I am having a bit of frustration trying to display an image save in a folder after upload in a datagrid. The image path is being return but the image does not displays. When I check the image properties is empty. THis is what I've been trying.
[Code]....
Here is where the image is being save: imagePath = "C:\inetpub\wwwroot\soweb\page_images\image1.png" If I change the path in the database to: page_imagesimage1.png, the image is display in the datagrid.
I am creating an Asp.net web site which will support dynamic data. When I am creating a dynamic web site from Scratch (from template in VS) all is working fine. But when I am trying to add dynamic entity (.edmx) file and running the application I am getting following error
"The method 'Skip' is only supported for sorted input in LINQ to Entities. The method 'OrderBy' must be called before the method 'Skip'. "
I have a datalist control on my aspx page which is bind with a datasource. i want to skip / hide first row when bind. is it possible? if so then how it can be done.
I have a GridView bound to a DataTable. The DataTable has a Deleted column that holds a boolean value describing whether the row is logically deleted; I need the row to physically remain in the table. Is there a way to skip over rows whose Deleted columns are set to true in the GridView's onRowDataBound event? The closest I could get is marking the row's visibility property to false, but this does not help me because it throws off paging and the GridView's alternating row color.
I have a datalist where I am displaying the Tickets for any conference. Now the posblem is that on the first page I need to display some custom data and attendees information so I need to start tickets from the 2 row and same needs to be done on the footer.I have used datalist so that the data looks like actual ticket. If something else is possible, which is a better solution please elt me know . e.g.
I have a gridview with two bound fields. On clicking a button i want to display the values in first row of gridview in two textboxes. But if gridview cell is empty i am getting the text in textbox to which the value of cell is given as -' 'i know my problem will be solved if i use the template fields instead. But i want a solution while maintaining the bound fields ,if any.
When I click on the Alphabets it will show the details of a player...however, when that particular letters has no details of the player..I want to show."No results can be found"..Is there anyway to do it?
i have a website which has a <IMG> and/or <asp:Image> in it.
The user has an option to upload an image. so if the user does upload an image it will be displayed in the stated controls above. but if they don't the control displays its alternative text or an "x" icon. can i just place a default image in it if there is no image reference to it to display?
I have a gridview in which I have two drop downs. One is populated with values that are static, so I have a regular sub that does that in the code behind. I tried to add code for databinding the other ddl to a datatable. I cannot get this to work. It just comes up empty. My asp code is fine, and the datatable definately has data in it - just nothing gets populated.
One other thing - the code for the static ddl has worked fine, but when I add this other block (either to the same sub as that, or dow the rowdatabound event) the static one doesn't work either.
Inside my repeater I'm calling an extension method like so:
[Code]....
he above is giving me an "Object not set to an instance of a object" exception inside the extension method. If I comment the above expression out, it works fine, and the items are binded wtih no problems.
im trying to use dynamic object in a databinding tag , it gives me error that the property does not exists even though i can see all the properties there in the vs debug mode
here is what im trying to do:
C#:
my method signature:
public static dynamic MyMethod()
ASPX:
in control itemtemplate:
<%# MyMethod().SomeProperty %>
if also trite the other way:
C#:
public static object MyMethod()
ASPX:
<%# ((dymanic)MyMethod() ).SomeProperty%>
But i dont know why it cant resolve the properties , even though i can see them when the databinder control throws an exception (its working fine outside the databinder tag (ie normal aspx tags <% %>)
I have a GV & a FV both linked to same sqldatasource.
When a GV row is clicked, the FV becomes available for editing the row but the GV as a result is reduced to only that row. I want to GV to remain showing all rows. I am using GV selected_index event to invoke "SqlDataSource1.SelectCommand=
I've created a templated user control by following the example on the microsoft support pages. I won't post it all but the important part of the CS file looks as follows:
[Code]....
I'm not sure if the whole _CurrentDataItem business is required, I don't think so.The problem I've got, is that I've tried nesting it inside a FormView control so I can use it to display a record from a database. My ASPX looks like this:
[Code]....
Now, the bound properties (TitleText and TitleSubText) bind correctly, but the nested / template content is blank when the page loads. I'm not sure if this is something to do with the order in which everything is loaded or because I'm missing some code in the SimpleTemplate to get it to bind (etc.).
I have a forms view with an EditItemTemplate. I would like to populate the EditItemTemplate using the code behind vs. mixing the data in the UI as so:
text='<%#Bind("Question") %>'
At what point do I do this? I thought it would be on FormView_DataBinding, but there is no e.item.dataitem like other databound controls. My issue is that I need to check criteria of the data prior so I know which inputs to make visible, to set properties of controls within the EditItemTemplate, and manipulate the data prior to binding (less of an issue as I can always just tweak the data prior to binding, but it doesn't solve my other problems).
I am having issues with databinding a textbox within a tab within a gridview. The textbox displays the data information properly; however when I try to edit a row in my gridview anything I type within that textbox is not saved in the database. Also my other fields for my gridview are editable, I am only having issues with this textbox within a tab. Here is the code:
I have a custom DataControlField class that works fine but when I try to use <%# Eval('???') %> with it I get an error."Databinding expressions are only supported on objects that have a DataBinding event. SharedG.ImageLinkButtonField does not have a DataBinding event."I can't get this to work,the DataControlField dosen't seem to have a DataBinding event to override or anything.I could use a normal templatefield itemtemplate etc.with eval but I don't want to rewrite this all the time. [Code]....
I was wondering what would be the best pratice to databind a gridview programmatically.Normally i put my databind code in the page_load() but is there a way to reduce the number of times the databind method is called?I mean... the page_load() method seem to be called a lots of times when doing callbacks with the grid.
