i need to display some text boxes, and have the ability for the user to "add another row"
i tried a datalist and a repeater, but it does not show anything at all, when the controls are blank.
<asp:DataList id="dlIso" runat="server" RepeatColumns="2" RepeatDirection="vertical" >
<ItemTemplate>
test</ItemTemplate>
</asp:DataList>
so in this case "test" does now show at all..
I have an ASP page with the following repeater:
[code]....
Why is the collection empty, when there are controls drawn on the screen?
(BTW: I tried adding/removing the EnableViewState="true" tag)
I have a GridView which works perfect when it is not empty. Now when the source is empty I want to show an empty GridView and to be able to insert rows inside.
I have this code for the page_load event:

but I got the following error:
Exception Details: System.NullReferenceException: Object reference not set to an instance of an object.
Source Error:

I have a table that stores the URL to files in a folder that should be displayed for download by the site visitor.
In the database all the urls are correct.
I have problems with this one:
"MediaFilesA Programmer's Guide to ADO.NET in C#.pdf" (this is how it is stored in the DB)
When it is displayed it cuts of and thus the URL becomes invalid.
Requested URL: /Finska Institutet/MediaFiles/A Programmer's Guide to ADO.NET in C
All the other ones work fine, i assume this one is not working cause of the # character? How can i fix this so that the url will display correclty in all situations?
I want to limit the records to 18 in every line, then the next records goes to the nextline?

<ItemTemplate>

I have a repeater control having columns in it.When I bind the control to a data source then some of the columns become empty when there is no data associated with it.I want to hide the column if there is no data associated with it.I was trying to implement a solution given in this thread:

However,I am not sure how to write the logic for hiding and showing the placeholder.I have written some code for the same but that clearly doesn't work.The following is the .aspx as well as the code behind which I am using:

I have a section of a page with a repeater control on it, taking information from a database, to display the latest information available to users. However it would be preferable to be able to format this information, so that it can have line returns, bold and underline in it. Rather than just single line plain text.
What is the best way to accomplish this? At the moment this is what I have: [Code]....
I have setup my business object to have a create_date and edit_date members both datetime datatypes. My company want to display the create_date and edit_date fields in a gridview for each transaction. The problem i have is that after insterting a record it will have a valid create_date but no edit_date and when displayed in the gridview it defaults to datetime.minvalue (My default). How on earth do i show an empty field in my gridview for a null datetime field in the database?
I am using similar architecture to the Imar Spaanjaars example of a tiered solution. With a few small tweeks it has worked well for me for ages. I am passing a List<Database> to my object datasource which connects to my gridview.
The datasource of the datagrid is a LINQDataSource which relies on the value of a dropdownlist. In addition, I want to use the footer to insert new records - so I'd prefer not to use the empty dataset template. I am trying to find a way to always display the footer regardless if the datasource is empty or not.
EDIT:
Is there a way to create an empty/invisible object of the type in the LinqDataSource?

I have a table called "Actors" in my SQL Server database. I want to retrieve all the 'actor names'from the ACTORS table and display into my .aspx page according to alphabetical wise. for example, the records starts with letter A should be displayed in a column, after that records starts with B will be displayed underneath that one,,,vice versa until Z.I don't want to display the entire actors name into one column because it makes my page looks awkward.
I showed all details in Repeater but in page it showing every item twice how to recover that....

View 2 RepliesI want to implement an image gallery in asp.net/C#. I am using sql server 2008, visual studio 2010 and .NET 4.0.
I have made a webpage and now want to display 6 images as thumbnails (and their names just below the thumbnails) at the center of the page. The format of the display is something like this:
[Code]....
Basic operation is like this:
I pull images from a database and then display them as above as thumbnails. The 1 2 3 Next> are links depending on whether there are more than 6 images pulled from the DB. So basically the numbering 1 2 3 4 Next> is dynamic depending on how many images exist. Can anyone give me a basic overview of how this an be achieved? Should I be using a asp:Repeater or a asp:DataList for this kind of a display?

got an example of a repeater inside a repeater (dataBound) code behind?
View 3 RepliesI have a user control that displays a shopping cart in an ecommerce application.
The main cart display is a repeater that renders as a html table. In one of those table columns, there is another repeater to display people associated with the products int he cart (it's a repeater in case there is a line item >1 with multiple people).
I've added an ImageButton that I want to use to change the person associated with the item. At first, when I'd click on it I was getting this error:
Invalid postback or callback argument. Event validation is enabled using <pages enableEventValidation="true"/> in configuration or <%@ Page EnableEventValidation="true" %> in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation.
So as an experiment I disabled EventValidation on the page (not the control it's self) and now I do not get an error, but I also do not ever hit the breakpoint I set in the innermost repeater's ItemCommand event.
So I wonder how I might do this without disabling EventValidation, because this control will show up on multiple pages and we don't want to edit them all. Also, I'll need to know not only the repeater containing the control's row that the event came from but also the row index of the repeater containg this one. Is this possible?

I'm so confused I wasn't even sure what to make the title so that it would make sense.
Here is what I have:

I have links at the top of the page that are the letters A-Z. What I want to do is click on one of the letters, then show only the div IDs that start with that letter. I can't figure out how to do this since I'm dynamically creating the ID names. I had it set up nicely with Javascript and CSS, but the function call was inside the repeater. The layout is changed now, and I don't understand how to make the div ID available outside the repeater.
I am using Nested Repeater repeater1 and repeater2 in my project . one button is there inside repeater2 but i cant use that button using e.commandname
so how to use that button and how to write code on it.
what changed do I need to make to my code for it to achieve what I'm after.
At the moment I am getting a "cannot cast to type" error message with the below code.
I have also tried calling the ItemDataBound method in with the parent repeater tags and had no errors but when I clicked on the button it would just move back to the top of the page and would not hide or show any data. Also I have made the div style to none but the first record still shows its child but the rest don't.

I am using a repater whose item template is having a dropdownlist. Now i want to access that dropdownlist from a button click event. Here is the code iam using :
protected void btn1_Click(object sender, EventArgs e)
{
foreach (RepeaterItem item in rptWord.Items)
{
DropDownList ddl1 = (System.Web.UI.WebControls.DropDownList)rptWord.FindControl("ddlWord");
}
}
But m getting ddl1 as null. For this i created a function which is as follows:
public void myFunction(object sender, RepeaterItemEventArgs e)
{
foreach (RepeaterItem item in rptWord.Items)
{
DropDownList la = (System.Web.UI.WebControls.DropDownList)e.Item.FindControl("ddlWord");
}
}
using this function iam able to access the repeater but i guess its not possible to call this function on button click event .
I have a sql database that on some field will have a empty string/field. I am using a Datalist to display my results. How do I not make the labels that are empty not display? Currently if the field is empty it will leave a space there which my goal is if the field is empty do not leave a white space instead move the other colunms up.
