int val = lstvRecordsCus.SelectedItems[0].SubItems[0];
The returned value is an int in a string datatype. I need the right hand side to return the value in int instead of string.
I tried Convert.ToInt32, it didn't work.
All the values that comes from SelectedItems[0].SubItems[0] is of type int.

I have a menu user control with image buttons like this one:
<asp:TableCell ID="tcDownload" runat="server" CssClass="MyMenuTableCellDownload" VerticalAlign="Top" >
<asp:ImageButton ID="ibtnDownload" runat="server" ImageUrl="~/Images/MyMenu/tb_download_1.gif"
CssClass="MyMenuIbtn" ToolTip="Download Results" />
</asp:TableCell>
In the codebehind, I handle the onclick for these to navigate to another page:
ibtnDownload.Attributes.Add("onclick", "document.location.href = '" + strNavUrl + "';return false");
Elsewhere in the user control, I have regular text menus like this one:
<asp:TableCell ID="tcMyMenuCust" runat="server">
<asp:Menu ID="menuMyCust" runat="server" StaticDisplayLevels="1" MaximumDynamicDisplayLevels="1" Orientation="Horizontal"

What I want to do is extend the menu choices by changing the image buttons to behave like the regular menus, while maintaining their look (image resource). That is, clicking on the image should result in a submenu dropping down to display subitems. I know it's possible to use properties such as StaticEnableDefaultPopOutImage to indicate that a menu item has child items. I also understand that menu items can have background images, but what if I simply want to use an image rather than text on a main menu item that drops down subitems when clicked?
Whenever I want to get selected items I have to loop through each item and see if it's selected. They even have a SelectedItem (no "s" at the end) member which seems odd for a CheckBoxList. It seems like a logical thing to have, does anyone know why they haven't added it?
View 4 RepliesI basically need some items in a grid however each item contains subitems so I need a +/- type button to show/hide them. Is there a control to do this or would it be easier to simply put them in a CSS table and use jquery or something similar to control the hide/show of subitems?

My question is this: what if there's an error and intFolderID does not get a value assigned to it. I'd like to at least instantiate it and give it a value of 0 so that I can do some validation. How do I assign a default value of 0 to this variable?
I am using Entity Framework with partial classes added on so I can use DataAnnotation attributes. Does anyone know how to add a data annotatin which will verify that a field is a whole number (or a DataType of int or long)? I'm surprised there is no [DataType(DataType.Integer)] attribute. I tried to create a custom attribute, but it doesn't work because the value it receives is always null:

I have a query which need to search on account table where search criteria looks at either partial name(string column) or partial accountid (integer column).
Linq doesn't allow tostring on integer column to find partial search. The example would be search account number which begins with 124. There might be account numbers like: 1247, 1249 etc which need to be returned. On the name side, searching for string that begins with joh would return john, johk, johp etc.
FYI: The query should return Account table records not annonymous types.

i'm using an entitydatasource to save an entity which has an nullable integer property with the default value 0,this property is bound to a textbox in a formview.I assume that when I leave the textbox blank the datasource should understand that I want the property to have null and set it to 0 by default, but it acts different way, it doesn't save the enity at all and gives the entity in Updated and Inserted events as null:

I have an integer field in my sql database and I have an xsd set up with all the CRUD operations. I need to put the value in a variable into the this integer field. Sometimes the value is 'nothing'. I have option strict on so there's no conversions going on by itself. If I hard code 'nothing' into the insert query, it works fine. Here's what happens otherwise:
1) If I put a variable into the query, when I assign 'nothing' to the variable, it becomes 0 so it puts a 0 into my database.
2) If I use an iif( ) statement, it also converts 'nothing' to 0
I don't seem to have any way to get a nothing in there if I don't specifically write 'nothing'.
I am using the following code,
vb Code:
Partial Class _Default Inherits System.Web.UI.Page
Public count As Integer = 0
Protected Sub Timer1_Tick(sender As Object, e As EventArgs) Handles Timer1.Tick count += 1
Label1.Text = "You clicked the button " & count.ToString & " times!" End Sub End Class
however, all the page ever displays is "You clicked the button 1 times"
We are using visual studio 2005 and SSMSE for this project. I had already created some pages which is capable of inserting and updating the values on the sql server. After inserting and updating it will redirect to another page to view the result. When I add a homepage, something just mess up. When I insert a new items for the table, it prompts a message, DBnulls cannot be converted to type integer. When I try to check at the sql tables, the data was inserted but I was not able to view the result on the other page.
