View 4 RepliesWhat I'm trying to do is to pull this data from a database, through LINQ.
However, on the next code behind page, when I type merchantid2.Text it doesn't work.
How do I get the value back from the cs code behind page, if it's already been displayed on the aspx?
<td>
<asp:Label
runat="server"
ID="merchantid2"
Text='<%# Eval("m.merchantname")%>'></asp:Label>
</td>
I want to use a dropdownlist control as paging options (50, 100, 150, 200) for a GridView control so I can reuse the user control on other pages that uses paging.The dropdownlist control will be in the user control page and the GridView will be on the host page. How do I reference the GridView control generically from the dropdownlist in the user control to set the PageSize property of the GridView control upon selecting one of the dropdownlist options. Any advice and if there are other means to accomplish such tasks to allow reusability.

I have a dynamic data bound drop down list, when the user selects thier selected item I have to use the autopostback feature.
Problem is: when the page comes back it is at the top of the page not where i have the control.
I don't really need it to focus back on the dropdownlist but to scroll to it, I want to do it in the code behind.
Any "New" ways to do it, I mean new as in code from like 2010 instead of old code from the early days.
I really don't want to use Page.Register new Script...... code if I can avoid it.
What would be cool is a ScrollToControl() Function for my code behind that worked but didn't register script.
I have a series of dynamic controls that I'm adding to a page. These are listboxes.
I am adding a handler dynamically e.g. AddHandler listboxname.SelectedIndexChanged, AddressOf listboxSelectedChanged
However, this subroutine looks as follows:
Public Shared Sub listboxSelectedChanged(ByVal sender As Object, ByVal e As System.EventArgs)
I'm trying to set a value for an HTML Element within my code-behind. I need to set a <div> elements "display" property to "inline". The way I have it coded is like this:
Code:
divContact.Style("display") = "inline"
Is this the right syntax? I only ask because it doesn't seem to work but I don't get a run-time error when the statement is executes. ???
On a typical form you have some fields and submit button. What event do I use to retrieve the values of the form from the post , process the forms submit?
How can I add page events to the code behind file (.cs file)?
I thought this would be easy but i cant find what i am looking for online
I have 2 pages, the first 1 has a button that opens another page. On this 2nd page the user selects a picture. When the user selects a picture the form closes. When they select a picture i want the image control on the first page to change.
I'm not sure how to do this, i guess i could set the image path as a session variable and reload the first page but again i'm faced with the problem of how to reference the first page from the 2nd
I have a repeater that retrieves questions from a database and displays them on the screen along with a group of radiobuttons. The radiobuttons display correctly and seem to work (only one can be selected per question), but I'm having trouble referencing the buttons from code-behind (C#) to see which button has been checked. So far I've been trying to access the radio buttons this way:here "current" references the index of the current question,
Repeater1.Items[current].FindControl("RadioButton1")
Things like .Checked (after the code above) do not work since the code does not recognize the returned item as being of type Radiobutton. The radio buttons are grouped, so if there is a way to find out via the groupname

I am trying to see if it possible to create a back button that goes back 3 pages and refreshes that page. The make up of my page is a little complex. The Home page has a password prompt that enables a multiview to be visible with a gridview of information. The gridview has a details link that has a 2 querystrings that gets sent to the details page. The details page has the ability to be edited and updated. this is why I wanted it to go back 3 pages. The code I am using to go back is
<asp:Button ID="Button2" runat="server" CausesValidation="False" OnClientClick="javascript:history.go(-3);return false;" Text="Back" UseSubmitBehavior="False" />

I have written a custom membership provider for my MVC 2 app, and it all works fine. I wanted to force people to log in as soon as they went to the site, so set the authorization section of the web config to deny annonymous users. As expected, when you try and access the site, it re-routes you straight to the LogOn.aspx page. The problem I'm having is that when it initially jumps to the LogOn page, it cannot find any of the files referenced in the html header section.
The strange thing is I set a path to a css file as follows:
../../Content/site.css
yet in the page it shows up as
../Content/site.css
I even wrote a html helper that uses Url.Content on the paths passed in, but this still does not solve the problem. If I go to the LogOn page after the application has initially loaded, it references all the files correctly.
I have a utility project that has an "XML" folder with two XML files in it, this project is then referenced by an ASP.net web project. I was wondering do you have to set some sort of build option to place the folder in the BIN of the website, or is there another approach to referencing these two files from the web project?
View 1 RepliesI have a web site that is hosted by Network Solutions. The hosting package I have includes support for ASP. I can place a simple aspx page on my web site and point to it with my browser and it appears to execute. What I'd like to do is reference a text file (for parsing) that is in the same folder as the aspx file. I have no idea what the absolute path is to the folder. How can I reference the file for reading if I don't know the absolute path?
View 3 RepliesBasically I need multiple code-behind files each containing different functions for a page. Different classes do not do this because they are not connected to the page so their methods require parameters I want direct control of the page without the need for parameters.
I can only seem to crete one code-behind file and I need many. I've tried putting the aspx page in the App_Code folder but this causes an error.
I have a page with a Textbox, a Button and a Label control. On Button_Click event , I store the value of Textbox in a variable called S using code behind.
I want to show the value of S in the Lable control using inline code but not using the code behind. ?
I'm trying to throw the exception back to Page_Load but the throw statement causes error: ArgumentNullException was unhandled by user code. How can that be fixed? Also, I can't see Label1.Text displayed on the page after the ArgumentNullException occurs because the page is not re-load. If there is no exception, it's fine to not reload the page. How can I see the Label1.Text displayed?
protected void Page_Load(object sender, EventArgs e)
{
try
{
...do something here...
}
catch (ArgumentNullException ae)
{
System.Diagnostics.Debug.Write(ae.Message);
Label1.Text = ae.Message;
Label1.Style.Add("visibility", "visible");
}
catch (Exception ex)
{
...do something here...
}
}

I am using Asynchronous File uploader ajax toolkit control.I want to get knowledge of whether page is posted back due to File uploader or not in Page_Load event of my aspx page.
For that i tried to use Page properties IsAsync, IsCallBack but even page is posted back on responce of File Upload these properties are false,only IsPostback property is True.
Why IsAsync and IsCallBack properties are false ?
I was thinking that since this control upload files Asyncronously, so atleast on File Upload IsAsync property should be True.But that is also false .
I have a straight forward SP that throws a divide by zero error like:
[Code]....
Note that even though I am calling RAISEERROR() its not getting returned back to my code if I use this try catch. When I remove the try catch like above it returns fine. I made sure that the severity level is >= 11 so it's not ignored. At this point I'm out of ideas because everything I can find published seems to say that this should work.
FYI my C# code is pretty straight forward I don't think it has anything to do with it as I have a wide open Exception catch and it's never getting called so I'm not posting it to keep this message brief.
I have done some changes to the Common.js file of the AjaxControlToolkit. How can i reference this updated script. I don't want to rebuild the dll again and again for each changes made to the script file. Can i do this?
