I just want to add and attribute called "pubID" to an image button with the value I give it and then call that value on the image button click event. This image button was created dynamically as well. At the moment this code is not working. When debugging it looks like Pubid is getting assigned a value but on the click event, the attribute isn't being retrieved correctly.

I have a dropdown list where I need more than just a bound value and a display value. I am using this in the page load event to add a custom attribute:
[Code]....
I'm actually looping through a sqldatareader for a list of employees, but for simplicity just consider the single option added above. When I go to check the attribute EmpNum for the selected option, I am getting "null":
[Code]....
Now the really weird part...If I add an option in the HTML source identical to the one that gets added in the codebehind, the javascript function works for that row, but not the row added from codebehind. Here is the rendered HTML for the SELECT:
[Code]....
If I select the 1st record (added from HTML source at design time) the alert says "12345". If I select the 2nd record, the alert says "null". I CAN get the value ("999-99-9999") and the displayed text ("John Doe") for either record, just not the EmpNum attribute, even though the HTML is exactly the same. I am completely stumped on this one.
I have a problem with a GridView that I can't figure out. It's inside an UpdatePanel and has been working fine for a long time. Today I have added a few lines to the code behind to add javascript to each row so that the user can just click the row to view the record. This works fine too, except that it breaks the paging of the GridView and I don't understand why.
Here is my code (The controls lstStatus and txtSearch are elsewhere on the page):
[Code]....
And in the codebehind the lines which break paging are the following three, in the RowDataBound event:
[Code]....
I've tried messing with the viewstate of the UpdatePanel, changing its UpdateMode to 'Always' and it's ChildrenAsTriggers property to 'True' but none of this makes any difference, and besides, it's been working for months as it is until I introduced these three new lines into the code behind.
Can anybody see why add these attributes to the row breaks paging?
I know a little bit of vb.net but don't know all that much about the asp.net technology. I do some volunteer work for a non profit organization and what I'm trying to do is integrate an image gallery into their site, instead of using an external image service that they use now.
After some searching I found an easy to use program that automatically creates the necessary thumbnails in a table.
However I want to add some functionality; when a user clicks an image for full size I want to add the option to click a button or link, to get to the next image.
I've done a lot of searching but couldn't find how to achieve this. I guess I need to find out the current image and then somehow jump to the next image.
How to implement this. Preferably I'm looking for something that is easy to implement. I'll have a number of different albums with a different amount of images. If possible I'd like to avoid having to rename the images so that they are photo1, photo2 etc.
Currently the image gallery looks like this : [URL] ....
I'm pretty sure I will need to make some changes to the viewimage.aspx file. Currently it only contains:
vb Code:
<img border="0" src="<%=Request.QueryString("img")%>" alt="" />
Not sure if you need to know the code that does the thumbnailing + creating clickable thumbnails, but I'll post it just in case it's needed
vb Code:
<script language="c#" runat="server"> void Page_Load(Object sender, EventArgs e){
// Modify these numbers for the thumbnail size you want const int maxWidth = 200; const int maxHeight = 200;
ArrayList pics = new ArrayList(); string html; int imgHeight; int imgWidth; foreach(string s in Directory.GetFiles(Server.MapPath(""), "*.jpg")){ System.Drawing.Image currentImage = System.Drawing.Image.FromFile(s);
[Code] ....
I got the code from here: [URL] ....

I want to add an attribute to the dataset declared below whose value is the value of one of the field in the row. So I want to add the id as shown below.
<root>
<Table id="GAS-405">
<apple>2009FA</apple>
<orange>3.00</orange>
<pear>BGPR</pear>
<banana>GAS-405</banana>
</Table>
</root>
This will me identify the node later in my application. Is this possible? Is this easier to do using XMLDocument?
Dim sdaFoo As SqlDataAdapter = New SqlDataAdapter("SELECT BLAH FROM BLAHBLAH", conn)

Is there a way to add custom attributes to @Page directive and also get design time support like intellisense for the same?
I have used Adding Custom Property to Page Directive in ASP.Net 2.0 as a pointer.
I would like to have a attribute which will give dev an option to select value from list. Something similar to EnableSessionState attribute. I do understand I need to define an enum for the values. But I cannot understand how to make it available during the design time.
I know there's been a lot of dicussion about removing inline styles that asp.Image control renders by default. I have applyed soultion mentionedhere. But I am facing another problem with this control. If I set Width and Haigth attributes on Image control and the result HTML is:
Source code:
<asp:Image ImageUrl="~/style/images/image_big.png" CssClass="someclass" runat="server" AlternateText="Image alt" Width="179" Height="53"/>
Result code:
<img src="style/images/image_big.png" class="someclass" alt="Image alt" style="height:53px;width:179px;" />
What I would like to have is separate Width and Height rendered outside style attribute. Like when having server HTML control. And let's say that I cannot subsitute asp.net image control with HTML server control.
Is there a way to somehow render Width and Height for asp.Image separatly?
I want to add a custom attribute to an asp.net RadioButton called Key which I'm using client-side for an ajax request.
What I'm finding is that my aspx markup which is the following:
<asp:RadioButton ID="rdoPost" GroupName=PreferredContactMethod" value="Post" onclick="DoStuff(this)" runat="server" />
gets rendered in the page as<span Key="ContactMethod">
<input id="rdoPost" type="radio" name="PreferredContactMethod"" value="Post" onclick="DoStuff(this);" />
</span>
whereas I'd expected (and hoped) to get the following
<input id="rdoPost" type="radio" Key="ContactMethod" name="PreferredContactMethod"" value="Post" onclick="DoStuff(this);" />
I've tried the same thing with an asp TextBox control and it works exactly as I'd expect simply adding the Key="myKey" attribute to the <input type="text"/> element.Is there a way around this with the standard RadioButton control, or will I have to inherit from the standard one to achieve the markup I'm wanting? Currently I'm using these attributes in JavaScript in the following way:
var key = rdoPost.Key;
I'm adding an attribute to my DataGridItem like this:

I have a menu in a user control with a sql database datasource. From what I have read online, the staticselectedstyle will only work if the menu control has a datasourceid defined. Here's what I have so far:
<asp:Menu ID="mnuMoESP" runat="server" Orientation="Horizontal"
ForeColor="White" BackColor="Transparent" Height="30px" Font-Bold="True"
Font-Size="Medium" Font-Names="Arial"
StaticMenuItemStyle-ItemSpacing="0" style="text-align:center" >
<StaticSelectedStyle BackColor="White" ForeColor="#402000"/>
<StaticMenuItemStyle BackColor="#5a630c" BorderColor="White"
BorderStyle="Ridge" BorderWidth="3" ItemSpacing="5px"/>
<StaticHoverStyle BackColor="#402000" />
<StaticItemTemplate>
<%# Eval("Text") %>
</StaticItemTemplate>
</asp:Menu>
and code behind:
private void PopulateMenu()
{
mnuMoESP.Orientation = Orientation.Horizontal;
mnuMoESP.Width = Unit.Percentage(100);
DataSet dsmenu = (DataSet)Session["menu"];
DataTable dtmenu;
dtmenu = dsmenu.Tables[0];
foreach (DataRow theRow in dtmenu.Rows)
{
MenuItem categoryItem = new MenuItem((string)theRow["page_menu_parent"]);
mnuMoESP.Items.Add(categoryItem);
categoryItem.NavigateUrl = GetNavUrl(theRow["page_path"], theRow["page_name"]);
}
}

i have an image and an imagebutton, they are inside a listview and get their imageurl from databinding, i would like to know, if maybe the databinding value is empty, instead of showing a big red x, is there anyway to maybe make it link to a default image when the value is empty instead?

I am accessing this xml file by using LINQ to XML in asp.net by using C#. I am able to access all the attributes of an XML node by explicitly specifying the name of the attribute. I want to write query on this xml file which reads all the attribute values of the xml node (In our example the node is SERVER) dynamically means I want to write the query which can read the read the value of the attribute Name & ID from first node, only name from second row, Name, ID & Parent from the third row , Name & ID from the fourth row, Name, Parent & Value from the fifth row & only Name from the sixth row without modifying the existing code every time. Once I add one of the attribute ( for example if I add the attribute ID in the sixth row ) in the above xml file then I dont need to modify my LINQ to XML query. My query should dynamically fetch the total number of attributes & display their values. Is their any way to do this ?
Just wondering if anyone has ever managed to find a way to have a datagridview image button column in a template field which display different images on different rows depending on some data element in the row. Our application needs to display a series of fees charged against an account column which will be either less then 500, 500 to 1000 or >1000. Some of those fees are charged at a full rate, others at a partial rate, and some are not charged at all. The user would like to see a simple 3-state graphic which would convey the simple info: full-charge, partial-charge, or no-charge. Sounds easy enough but I've not yet managed to find a way to do this. Every time I attempt to modify the individual cell's graphic it seems to want to change the graphic for all the rows.

I have four Imagebuttons that I want to disable depending on the Role the user belongs too. I know how do do this in a gridview or detailsview but for some reason it isn't working on just a plain form. So when a User who is not in the "Admin" role logs onto the page he either doesn't see the button or the hyperlink has been disabled thus not allowing him to proceed any further.
