C# - Weird Exception In Linkbutton In A Datalist
Apr 17, 2010
I have written this datalist :
<asp:DataList ID="DataList2" runat="server" Height="16px" Width="412px">
<SeparatorTemplate>
<hr />
</SeparatorTemplate>
<ItemTemplate>
<asp:LinkButton ID="LinkButton1" runat ="server" Text='<%# Eval("Name") %>' PostBackUrl='<%#Eval("Url")%>' />
<br />
Description:
<asp:Label ID="new" Text='<%#Eval("Description") %>' runat="server" /> </ItemTemplate>
</asp:DataList>
</div>
It raises an exception saying that the linkbutton has to be placed in a tag that contains runat="server" although it exists. Here is the trace
[HttpException (0x80004005): Le contrôle 'DataList2_ctl00_LinkButton1' de type 'LinkButton' doit être placé dans une balise form avec runat=server.]

Have an application which publishes XML data across webservice using SOAP.
The data is pulled directly from an Oracle database and parsed into XML but for some reason the data being pulled out of the DB is throwing the following invalid XML exception.
Have done a bit of research and it looks like it may be a NULL character somewhere in the data which XML parser doesn't like.
Just wondering if anyone had seen this before and if so were they able to fix it at application or database layer?
Here's stack trace...
[code]....
UPDATE: Here is a selection of data being published.Just plain text basically, this is how it exists in database columns, have included as comma separated.

I have a radcombobox in radgrid nested inside FormTemplate:
Code:
<telerik:RadComboBox Skin="WebBlue" Width="250px" Height="150px" runat="server"
ID="TitleCombo" OnDataBound="Title_DataBound"
SelectedValue='<%# Bind("Title") %>' AppendDataBoundItems="true"
OnSelectedIndexChanged="Title_SelectedIndexChanged" AutoPostBack="true" />
then i insert an item to the top of list (at zero index):
Code:
protected void Title_DataBound(object sender, EventArgs e)
{
var item = (RadComboBox)sender;
item.Items.Insert(0, new RadComboBoxItem("Select title...", "0"));
}
It works perfect but, IF the Title field is zero and you Click EDIT LinkButton it throws an exception: Selection out of range Parameter name: value I would say that it's expected as zero index does not exist at the moment when i click edit button. I bind the combo from within RadGrid1_ItemCreated event.

I have a datalist and in its header template I have a linkbutton. In my codebehind file I wrote as I've always written: (LinkButton)(DataList1.FindControl "LinkButton1"))).Enabled = false; but this gives me the error: Object reference not set to an instance of an object. How can I access this linkbutton?

I am loading an aspx page into a div using jquery.load(). The aspx page loaded into the div has a datalist. Each datalist item has a linkbutton. My problem is that the linkbutton is not causing a postback though. Strangely, if I change the linkbutton to a button, it does postback. Also, when loading the page normally (not from a jquery.load event), the linkbutton performs correctly. What is it that causes the linkbutton to not cause a postback when loaded this way? And is there a better way to handle this?

I have a LinkButton that is databound to a description. Sometimes the descriptions are very long and unorganized so I would like it to show for example 75 characters and then append a '...' to the end of any description greater than 75 characters. I found this snippet which pretty much is exactly what I want to do :
from [URL]
[Code]....
I just cant figure out how to do this for the LinkButton in my ItemTemplate in the DataList.

Very new to ASP.NET (using C# behind) and am having trouble figuring out the following scenario. I have a DataList that is populated (code below) and wanted each cell to be clickable. When the cell is clicked I wanted to know the unique ID for that cell. In my code behind, my OnClick method looks like this:
[Code]....
However I never get there. It seems as if the linkbutton always refers to some javascript callback function and just reloads my form. Am I using the wrong control for what I want to do? From this click I want to look up more information from the Key (will roll up the datalist or set visible to false, then supply the new data on the same page)DataList:

Google's webmaster tools has started showing some very strange internal links for my site. It appears "normal", but I'm not sure what to make of it. If you use parentheses and put in a single letter, then put literally anything in parentheses after that, the link works. I did a search for any other MVC sites so I could see if they had the same behavior. Microsoft's site came up at the top of the list with an odd link as well. The search terms were "asp.net mvc site" and the first link I got was for: [URL]
I don't like this at all. You can change the S to an A or any other letter, and then put any text you want in the next section. Anyone know how to stop it? For the life of me I can't see anything wrong with my routes. I used MVC so I wouldn't have strange url's floating around in search engines so this is pretty disappointing. Nearest I can guess from the Google "internal links" list is that it may be a cookie. But I can't find any circumstance when I view the source on my site where I see anything but the proper relative links.

Every few days when my webpage is accessed strange characters are embedded in the URL like this:[URL] I did some searches on the internet and found that if the characters begin with the letter 'S', it is the session id used when cookieless is set to true. In my case the beginning letter is 'A', and i couldn't find anything about that. This is bad because once these strange characters appear, all the submenus in my page will disappear (I had another post about his menu problem in here:[URL]
Once I restart the webpage in IIS the URL will become normal again, but it will appear again in a few days.
Does anyone know what these strange characters (that begin with 'A') are? How to avoid them?

Recently I got a strange behavior, the website hangs and just doesn't reply unless I go to iis and restart either app pool or whole IIS - BUT what is the most strange thing is that in case I go to remote desktop of the server and try to access it locally it DOES work just fine. I read couple threads about deadlocking and hanging because of memory leaks and non closed sql connections BUT why it still does work from the local?In case there is something wrong with the code - why does it still work from locally?

try to figure out what is wrong with my code but I'm lost. I've a ModalPopupExtender, triggered in code behind by the onClick event link button. The FIRST time I display my popup, it works well and if I close my popup using javascript, it works and I can get my popup back by clicking on my linkbutton again. But, if I click the "Save" button of my popup (which save data and close the popup), I can't get my popup to display again. Even if I close my popup first using javascript and then calling my server side code to save my data, the result is the same, I can't display my popup again. Seems like the postback "break" it.This popup is in an conditinal UpdatePanel and event trying to manually update the panel after the popup.show() method change nothing.Finally, I checked what server sent back to the browser using firebug and I can confirm that I received only view state information (no UpdatePanel to update), even after calling panel.Update().

I have a crazy issue when tabbing from one textbox to another.
This happens on a webpage which contains about 20+ textboxes, and this happens on the same textboxes, and I have no idea what is the cause.
When the cursor is in a textfield, I type in a value, hit tab, the focus goes to the next textbox, I hit tab, the focus stays in the same textbox, I have to hit tab again to go to the 3rd textbox.
This is annoying because the user is types their values, hits tab, starts typing values for the next txtbox, only for the cursor to stay in the pervious txtbox.
We use IE8.0
