Grabbing .net Controls In Javascript?
Feb 11, 2010
I have a page where it is getting overwhelmed with code like:ar textBox = $get("<%=textState.ClientID%>");This requires me to have my JavaScript inside the page instead of nicely tucked in a js file. Is there a better approach to this?
document.getElementById doesn't work because then I end up with code like this:
var textBox = document.getElementById("originDestinationControl_textState");
var textBox = document.getElementById("ctl00_ContentPlaceHolder_originDestinationControl_textState");

I have a drop down list control that I need to pull the value from in the code behind of the page, modify it and redisplay it. The modifying and redisplaying I've got no problem with, it's grabing the value from the drop down control.

I have a Gridview where some columns are populated with numbers of type nvarchar() and some columns are filled with numbers of type int I am trying to grab the a cell from a selected row that corresponds to a Table's KeyID and assign it to a label like so:
Label1.Text = MyGridview.SelectedRow.Cells(8).Text.ToString
Problem: If the Gridview column 8 has numbers of type nvarchar() it works fine But if column 8 has numbers of type int , it does not work. It's probably simple, but I dont see it.

We have a GridView2 in GridView1 EditTemplate.And we have a button (commandname="Update") on GridView2.When Button1 is clicked GridView1 goes into edit mode and displays GridView2.Now when Button2 is Clicked, we want the cell[0] value of GridView2 to be displayed as Label1 Text on GridView1 and comeout of the GridView1 edit mode.Basically we want to capture gridView2 cell[0] value and display that on Label1 of GridView1.We have written the below code. But we are unsure on how to grab GridView2.cell[0] value and display it as Label1 text.Can someone please assist us with this?Also, we are not sure if we can use rowupdated event for this. Please also guide us which events we should be using to achieve the functionality.

why I couldn't get the variable from the URL.
<meta property="og:title" content="<% Response.Write(Request.QueryString["title"]); %>"/>
For some reason the code, <% Response.Write(Request.QueryString["title"]); %>, does not retrieve the data in this case. It works fine if I put it in the title tag though.

So far it seems like I get something figured out then run into another issue... Anyways, I was finally able to grab an ID from a table and enter the value into a Label using this code:
[Code]....
Now i want to make things trickier by grabbing the last value enterd. Now there will possibly be multiple people using the application simultaneously, i think it is still possible to do this. Here is the statement that enters VALUES into the table that generates the CaseID that i want to grab from:
[Code]....
From what i have researched, I may need to do a WHERE some where to grab the @@IDENTITY. I am having trouble figuring out where the @@IDENTITY goes, and possibly the correct syntax as well.

I have a registration form which is working perfectly well, I need to enhance it slightly from where it is. As it is users are able to register for an account wether the email has been previously used/allocated in the user db.A client side call to the IsEmailAvailable function works great, just not working correctly server side. Here is the code.
My function:
[Code]....
And my if statement:
[Code]....
So my question is, how can I pass the end value of the IsEmailAvailable function to my if statement correctly.

I'm using asp.net - I need to grab live data from a website. Here's an example:
[URL]
That website provides live data share prices. I need code to retrieve the share price from the website and display it in my own page. I know you can get share price widgets online but all I need is a simple way to retrieve the share price values.

I have a number of 0-12345-67890 and I want to capture 0123456789 in a named capture group. I got this far:
@"(?<upc>d-d{5}-d{5})"
Which captures the string as-is. How do you skip the dashes while grabbing the number as a single named group? BTW, this is ASP.NET Regex.

In one of my web app's pages, the code behind needs to grab the UserId of the person logged in, so that it can then be inserted into a table which was added to the original aspnetdb.mdf. This table contains a column with a uniqueidentifier primary key which is in direct relationship with the aspnet_Users table; however I seem to have trouble retrieving the UserId. This table contains the additional information of a user which is not included in the provider, and it has a one-to-one relationship with aspnet_Users.
I hope this makes sense. I haven't written any code for it yet; I'm only at the thinking part of this stage. But my mind keeps going blank.(perhaps I need a break from the solution???).
I am using C# in my Web app's code behind.

I created a base Controller for the other Controllers to derrive from, and in that controller I overrode the OnActionExecuting method so that each time any Controller executes a method, I can run some code. In that code I added a value to ViewData, and in the Master View I want to either display certain items or not based on the value of the ViewData item set. The problem is, once I get to the Master View, the ViewData doesn't have anything in it. I am not sure what I'm doing wrong.

I think I summed up the question in the title. Here is some further elaboration...I have a web user control that is used in multiple places, sometimes more than once on a given page.The web user control has a specific set of JavaScript functions (mostly jQuery code) that are containted within *.js files and automatically inserted into page headers.However, when I want to use the control more than once on a page, the *.js files are included 'n' number of times and, rightly so, the browser gets confused as to which control it's meant to be executing which function on.What do I need to do in order to resolve this problem? I've been staring at this all day and I'm at a loss.

The requirement is like the users should enter data and should be able to see the entered data before final save. So, I've taken a gridview and binded it to a temptable which will don't have any data initially, so on the first page load the datasource will be empty and the emptydatatemplate will be shown to the user. On this EmptyDataTemplate I've prepared a dataentry screen where the user can give the information and can save the data. After saving the data the data will go to the temptable and the gridview will get populated with the data the user has entered. For next go, the user can enter records through the gridview footer row. In this way I'm doing my things.
Now I haven't done the validation yet, I wanted to do a validation of the user input on gridview emptydatatemplate and gridview footer as well. In order to do that I've created one Button object on RowDataBound and assigned the gridview emptydatatemplate save button against it and also binded one javascript function with this button like below.
[Code]....
The javascript is working fine and returning boolean values based on the validation done.
But the problem is after I did this validations the RowCommand event of my gridview is not firing. I'm inserting this records on this event only based on the commandname of the button. But if I remove this javascript validation everything works fine for me.

In the Script documents that asp.net automatically generates how can I surround the whole generated scripts with try/catch statement to avoid 'Microsoft JScript Compilation error'
My issue is: i got a DevExpress control (ASPxGridView) that added and set-up in run time, since i activated the grouping functionality in the grid I still get JS error says ';' expected whenever i use (click) on one of grouping/sorting abilities, I activated script Debugging for IE, in the JS code turns out that there is no missing ';' and once i click ignore for the error msg that VS generates every thing works fine, and surly end-user can't see this msg so i figured out if i try/catch the script that may help avoid this error.

This program in asp.net 2.0 is a Spanish/English Dictionary.
It consists of two textboxes,one button and a datalist. The datalist is bound to an acces database consisting of two columns; One Spanish and one English. When a user enters a Spanish word in textbox1 and clicks the button, the meaning of the word appears in textbox2. Now sometimes a user enters a word that is not in the database. I want, in this case, to have a javascript messagebox to popup saying “Either the word is not listed or misspelled”.
I tried several javascripts to popup in code behind but that did not work. I know that a clientside should be included but I am not able to do that.
The sub below is the one I am using to fetch the words and it is working perfect as long as I enter a word that is already in access database. The words in the rows in database are separated by hyphens so I am using a “Split” fuction which is also working perfectly.

I have the function put here like below:
$(document).ready(function () {
UserControlNameInit();
});
The script are put in the following and the block is in the .ascx page.
<script type="text/javascript">
</script>
However, the function UserControlNameInit() does not run when the page loads. It is showing in the page source. I can still call this function through FireBug console by manually typing the name of the function.
I did the same way with other user controls, and it works. Just 1-3 user controls are not working...

I have a page where there are two forms and a single submit button. Second forms submission depends on success of first forms submission status. So when button is clicked i have javascript to submit first form.
