Forms Data Controls :: Selecting Radio Buttons In A Gridview With Dataset From Linq Query?
Oct 13, 2010
I've got a gridview that will allow clients to edit options they've already entered on another page. The gridview has three radio buttons in it each with a value of 1,2,3. The option value in the dataset is 1,2 or 3 respectively. I would like to have the radiobutton with the corresponding value selected in the gridview so they can see what they previously chose and will then be able to edit, if they wish.
I have two radiobutton list .I want show an image on selecting two radiobutton in asp.net c#..I write the code in page load but its so me an error Object reference not set to an instance of an object. tell me code for it and in which event i have to write that code.
I have a form where i want to view all columns from a table.I have a textbox and differeent radio button having values of each column.On click of button.I want to view all the columns as per selected row/rows from value given
I'm trying to find an easy way to view the query that has been generated as part of the LINQ to DataSet syntax in my application. I found Scott Gu's blog and his creation of the Linq to SQL Debug Visualizer but it doesn't appear to work for my application. I am using OracleClient if that is important.
My next step is to simply configure the Oracle Manager for the database to see the query but I can't believe there's not an easy way to view this generated query.
I'm new with programming. I have a GridView that have the specific user data. When the user log in I retrieve the data for that specific user. All I need is; How do I make the gridview get the data of the logged user using a datatable that has a query. Just bind it with the datatable.This is some code that other programmer made, I continue his work.
I have a table, that contains a number of rows, in each row there are three columns that are mutually exclusive. What I need is to be able to have radio buttons that are linked across the three columns.
I'd like for where there is a 1 for it to display a checked radio button, and where there is a 0 for it to be unchecked. This can then be edited by clicking the radio in another column where necessary.
I have a formview that runs of an SQLDS, very simple stuff. Inside that form i have various fields, one of them is a credit field, one of them is a debit field. Now i have put a radio button list with two radio buttons (credit and debit). What i want to do is when the "credit" radio button is enabled i want the "credit" text box to be enabled and visa versa.
I know how to reference an object inside a formview, but i am confused, do i reference the radio button list and then the list items inside it or?
"Radio Buttons Are Not Mutually Exclusive When Used in a Repeater" according to KB #316495 http://support.microsoft.com/kb/316495. This bug also exists with ListViews, and I am having a hard time developing a workaround. Is there a solution or workaround available? I'm using Visual Studio 2010.
(Here is my ASPX. I want rbGroupedSession and rbFees to be mutually exclusive. Databinding and setting controls visible attribute to true/false is done in the code-behind. I'm also setting the RadioButtons "GroupName" property correctly in the code-behind, but it gets changed when rendered in the browser -- which is bug KB #316495)..
how do i go about looping through each group of radio buttons and getting the text of the selected radio button ?the code displayed above is created dynamically ... in my aspx file i have the following code
I am pulling some dynamic data from database SP (data will change). I need to show that data into row format with radio buttons and i need to retive same data from the page (as user selection on radio buttons values) to save data to DB. create such page with data.
Am building a Form for out intranet that runs on ASP.NET and C#, it is to be a survey from a SQL database. I have the connections setup can pull informations/Questions from the database. I am having a problem with setting up radio buttons within a datalist, ive never done this and i know they require unque names.
It is to be 4 radio buttons per question where only one can be select, i know how to group just not via a datalist with unique names
Is there a straightforward way to create a dataset after querying a dataview? The query itself returns DataRowView objects, which I cannot get to work with CopyToDataTable().
The query looks like:
Dim dvQueryView As DataViewdvQueryView = (dataview object of large dataset) detailTableQuery = From rowView As DataRowView In dvQueryView _ Order By sSortOrder _ Select rowView _ Skip nQuerySkipRow _ Take nQueryCountRows
I only want a small selection of records from the large dataview and use those to create a smaller dataset. The large dataset stays in place while multiple views are created from it, and then from those views I want to create the smaller datasets.
I have a web application that shows a page containing between 6 and 20 AJAX UpdatePanels, contained with Custom Web (.ascx) Controls.
You can see an example of such a page here:
The problem I'm getting is that when the user FIRST clicks any of the radio-buttons on any of the controls in the page, ALL the radio buttons that have an active selection ALSO fire an rb_CheckChanged event (see application log below). On subsequent radio-button clicks, only that RB fires the event (as expected).
This behaviour is having a dramatic impact on performance. The page loads quickly, and a "normal" RB click provides an AJAX update correctly within 1 second. The problematic first RB click, however, takes up to SIX seconds to process, which is unacceptable from a user experience standpoint.
Developed in VS.NET 2008, ASP.NET 3.5. Also I converted the "Web Site" solution to a "Web Application" (pre-compiled) and got the same performance (still too slow). Release builds run only marginally faster than debug builds.
Why would a single RB selection change cause all RB's that have a "selection" set on them to also fire? (The "selection" is determined through database settings every time the control is populated, which is called from within the parent page control's Page_Load function. This selection is determined also at first page load, since all the controls get populated then, so why would the clicking of an RB cause them all to fire an event, and only once? That's what I don't get...)
Not sure if this is an AJAX issue, or general ASP.NET UI issue, so I'm posting in two forums on this one.
I need a Listview that will show info from several database tables. My delete button, will not delete the record from the database. I cannot get DeleteOnSubmit() to work at all. I am in the very beginner stage. This is my first project. I thought this would be a good project for learning purposes.
I generate the TableRow and TableCell base off XML data file. When the submit occurs I can not access the data values from the radio buttons that are generated. I try to get the data in the following manner:
