i am doing a web page in asp.net which holds logos of members in the page in a grid view.each cell is a link to the relevant member's website.
i want to popup an image of the member's website when the mouse is hovered over a certain cell. for this a snapshot of the website is stored in a database an for the onmouse over event i want to make it pop up.
i want to know whether using ajax or JavaScript is more appropriate for this problem.
i want to know how this can be done.

<asp:Button runat="server" CssClass="txtdisplay" ID="Button1"

View 7 RepliesI've the Javascript code to do a confirmation before deletion of some records
function confirmDelete()
{
if(confirm('Delete all?'))
{
return true;
}
else
{
return false;
}
}
I've the button code here
<asp:Button ID="btnDelete" runat="server" onClientClick="return confirmDelete();" onClick="btnDelete_click" />
If i've the button outside an update panel (basically i'm using RadAjaxPanel by Telerik) it is working fine. But when the button is inside an ajax panel, even if i click OK for deleting the records the server side code is not called.
i just made an onmouseover and onmouseout event using javascript and called the functions from the asp image tag like <contol.....onmouseover="thissss()" /> my question is why do i need to write javescrit for this? have heard so much praise of asp.net and c#! is there a way that is code to handle these events for all types of object using the .cs file (c#) directly?? i would assume the code will be under the page load event.
note:-
do not give answers assuming that the asker is a new bee consider him a completely un-educated person when it comes to coding )
I have a WCF 3.5 service with JSON and a aspx page consuming it by using ASP.NET Ajax Library
I was able to call service succesfully.In the aspx page I wrote my Java code directly and then I wanted to modify my JS function but it is always picking the old JS function code
I even restarted the machine no change, looked up on the internet, msdn and I have Default pool with Integration mode

I am currently learning dotnet (having recently learned ASP Classic) and i have come across the Menu Items and their ability to be based on the sitemap.
I love this idea and would like to use it on my demo site that i am building. However i cant seem to find a way to replace the links with images. I did have a look on google and noticed people wee using the ImageUrl method but said you have to code that yourself. I dont know how to tell it that imageUrl is ... well an image URL.
And then, should this be doable, is it possible to assign an onhover/onmouseover event to change the image?
I'm having a bit of difficulty setting a variable from the code behind and utilising it in the ASP.NET page (setting it as the value inside a textbox). My webpage simply errors and says it does not exist in the current context. The variable is declared and set all in the Page_Load method.
Here is the relevant ASP.NET code. I assume you will not need to see the code behind, as I have tested outputting the variable via the codebehind (using Response.Write) and that works fine.
<asp:TemplateField HeaderText="Initial Path"
SortExpression="Initial_Path">
<EditItemTemplate>
<asp:TextBox ID="TextBox6" runat="server"
[Code]....
What's not working is just the <%= initialpath %> in the ASP form. It simply just doesn't show anything, like the variable is assigned nothing
I have 2 separate code-block asp.Net expressions in an aspx markup, with an html content between (span element in the example below). In the first code-block, there is "i" as an increment variable for the for loop.Then the code-block is cut with an html content.And another code-block expression is opened but as I see I can reach the "i" variable which was declared in the previous code-block.
So, how asp.net handles -compiles- the pieces of code-block experrions declared in the mark up? Does it check the semi-colons and generates some anonymous methods which will end up with many calls to Response.Write in the last place?

I'm converting a string to integer and than inserting this integer in my post table.
int currTopicID = Convert.ToInt32(id.Text);
SqlCommand cmd = new SqlCommand("INSERT INTO post VALUES(currTopicID)", con);
The problem is that currTopicID isn't being recognized as an integer when i do the insertion.
Following is the code to insert userName from session and PageName into table to keep record that how many times a user does hit a particular page.
To avoid repitition of code I want to put the code in one class and want to inherit same code in each page.

I have a site which I need to modify and add phone numbers based on what branch is being displayed. I have NO clue what-so-ever on how to do this.I have a .aspx file which is using another file as its code behind. My first question is: If I want to add "if statements" into this code, do I add them in the .aspx file or the code behind (aspx.vb) file? Next question is: A statement like
"<asp:Literal runat="server" ID="ltlBranch" /> Employees"
is using ltlBranch to place the branch name in front of Employees. Can I use ltlBranch as my lookup variable? In other words, is this valid coding for asp?
If ltlBranch="MainStreet"
show the rest of my code[code]...
Should I be creating a sub-routine within the codebehind form and then calling that routine? I am clueless on how to go about this, and am just trying to get a starting point so I can look up more info on it.
for(var i=0; i<<%=Model.Mydatalist.Count%>;i++)
{
//then I need to pass i to Mydatalist like Model.Mydatalist[i]
}
//var myJSdata="<%Model.Mydatalist["&i&"]%>";
is not working.. as system see i (i's value) as a string, and will throw exception: cannot convert string to int.
I guess I'm missing something here, but I can't find a way to pass a simple variable from my code behind file to the .aspx page. In code behind I have:
Dim test As String = "test" and in my aspx page I try: <%=test %> that gives me the following error:
Error 2 'test' is not declared. It may be inaccessible due to its protection level
I'm looking at a routine that returns a variable name and value in two fields from a table, the intent is to then assign the value to the correct variable.
in C# the statement is
Session[dr["SessionKey"].ToString()] = dr["SessionValue"].ToString();
My code is unfortunately VB. I'm having problems with the first half of the equation - setting the variable name in VB.
Here are 3 scenarios:
namespace NS
{
public partial class A: System.Web.UI.UserControl
private Variable v;
protected void Page_Load(object sender, EventArgs e){
if (!Page.IsPostBack) v= new Variable();
....
}
}
namespace NS
{
public partial class A: System.Web.UI.UserControl
private Variable v = new Variable();
protected void Page_Load(object sender, EventArgs e){
}
}
namespace NS
{
public partial class A: System.Web.UI.UserControl
private Variable v;
protected void Page_Load(object sender, EventArgs e){
v = new Variable();
}
}
When does the variable "v" gets created every time for the 2nd scenario? Is the 2st scenario is equivalent to the 3rd one?

I'm making a page with a DropDownList (called ddlSupp) that contains several suppliers, and I populate it with an SqlDataSource, all in front code.
In another part of the page I make a CheckBoxList, and populate it again with an SqlDataSource. The select command of the SqlDataSource is a procedure call to my MySQL database. However, what the CheckBoxList gets populated with depends on who is selected in ddlSupp. How do I make a variable in front code that will take the value from ddlSupp and populate my checkbox accordingly?
Here is my code:
[Code]....
I get a MySQL error at (<%$ddlSupp.SelectedValue %>) so I know the wrong value is being passed into the query. How can I fix this?
How can I call a .net method in inline code using a javascript variable?My code looks like this:
for ( var i = 0; i < numberIterations; i++ )
{
var result = <%# GetFilterTagURL( myArray[i].Value, false) %>;
//do stuff with result
}
This block is inside a javascript block; the GetFilterTagURL method is a a .net method and I want to pass the variable myArray[i].Value as the first parameter.
UPDATE:I guess that, as you say, I'll have to create a web service to achieve what I want.
I have a problem to pass along public variables from C# code to the HTML code. I assign the variables in the Page_Load event and then pass along them to the Panel and Image control in the HTML code.
