I'm trying to figure out how to access controls that are added to a panel in a code behind file.For example, when I click a button, I add a radio button list to the panel.How do I access the selected item from that radio button list? I get an error saying it is not defined, even though list gets generated..
I have a repeater control in my page. I need to have a radio button in all the rows(Item template) on checking an radio button the remaining radio buttons must unchecked.
Since setting item.selected to true will lose the mutual behavior and setting list.SelectedValue (readonly) doesn't get any button selected.
I am using list.SelectedIndex to assign the selected button. as follow :
//step 1. find the item by value ListItem item = list.items.FindByValue(obj.ToString()); //step 2. find the item index list.SelectedIndex = list.Items.IndexOf(item);
I make it into an extension method. But feel stupid about this procedure to simply just assign a selected value. does anyone have a better approach?
I'm learning asp.net and c#, and can't figure out why this won't work for me.I'm using a label control and a radiobutton list control. Basically if you select radio button 1 I want the label to say radio button one , radio button 2 for the next one and so on. Here is the code I thought would work.
I want to present a list of delivery options to end users which will be in 3 columns - service description, radio button (to select) and then the price of the service. Also I want to auto postback when the user selects a service from the appropriate radio button - e.g. :

I have set this up using a repeater control and stand alone radio button, plus literals to display the text elements all within a tabular structure which looks OK. I have actually overcome the issue where by default you can select all radio buttons using the prescribed javascript fixes I found when searching. This way offers me control over the formatting which is important.
However it does not seem that intuitive to pickup the selected value of the radio button this way, especially with the auto postback - I am having issues trying to access the selected radio button to interpret what the user wants.
It would seem much more appropriate for a RadioButtonList but I can't work out how to override the default formatting, and also how to insert extra table columns for the price etc to keep it all nicely formatted.
So either I need to crack the interpretation of the current setup or to find out is there a way to hijack the default setup of the RadioButtonList?
I have a databound Gridview (with a LINQ datasource). The gridview displays questions from the SQL DB to the user. I've inserted a radio button list into the gridview with 3 horizontal radio buttons with fixed values of 1,2,3 for the user to select. I have a question ID, a tempuserID, and AnswerValue columns set up in the database. It all works nicely.
After the user selects radio buttons, I would like for them to push a button to submit the QuestionID, the associated Radio Button Value (AnswerValue) and their tempUserID into the DB. How do I do this? I'm not sure what to do next and what VB/LINQ code to put in the code behind file in the button click event handler. I'm also not sure on what to use for the tempUserID, can I use the sessionID? I'm using VB and here's my code:
I have a Gridview with Radiobutton selection and two text boxes and two buttons.
What i need is to like search and extract functions.
My Gridview Initially contains all the data in the table. In one text box, like if i want to search "Learning" in column FIRST NAME and i type "L" in the text box and click the button, all values from the column FIRST NAME starting from "L" should be listed in the Gridview, so that from there user can select "Learning" and click another button to extract values corresponding to it in the another Textbox.
I have a table in my form, where I put n-rows, every row contains 1 RadioButtonList, when user select the item in RadioButtonList, I need to get the index of selected Item, without updating the page
i have a grid view with radio button...schedule/approve/reject...by defualt schedule radio button is selected....but when i chage radio button selection option to anyth other than schedule it still store only schedule in DB.wats the pblm?
[Code]....

when i click submit button i got this error
Invalid postback or callback argument. Event validation is enabled using <pages enableEventValidation="true"/> in configuration or <%@ Page EnableEventValidation="true" %> in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation.
so i set the enableeventvalidation=false
now i dint receive any error but when i set breakpoint on the funtion which called on buton clik it still got the value as scheduled for the radio button..spent almost half day for this.. all this while this was workin after i add the moralpopupextender am facing this pblm...now i tried removin that extender but still pblm exist.
For every search result I create a dropdown list with 2 month booking overview.
<ddl> <item value = "1"> January - February </item> <item value = "2"> February - March </item>
etc.
Then I call function to generate 2 months calendar view, which has two parameters generate(startmonth as Integer, sku as string)
Everything works when I hardcode starmonth as some integer.
I spent all day with no progress on how to pass value. I need a guide. I guess second problem will be to restore changed dropdown values on Postback, but one step at a time.
But what I want to do, to pass selected item value, to function, that would change view for property associated with this dropdown.
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 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:
[URL]
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 to access a control inside a repeater and change its properties. To enable it or not. I got an erorr message Object reference not set to an instance of an object. Here is my code inside a method. protected void
rptCAP_ItemDataBound(object sender, RepeaterItemEventArgs e) { LinkButton lnDel = (LinkButton)rptCap.FindControl("lnkDelete"); lnkDel.Enabled = false; //<<<<< this is where the error occur }
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 have string which came from the database,now i want to compare each charater of the string with the radiobuttonlist value and check box list value and select both radiobutton list and checkboxlist.

On my website i have got a product for sale page, which has a ryt side bar with filter options while the left side bar shows the filteration results. On my ryt sidebar i have used accordion with the repeater control which display the searching criteria from database.For instance I have 2 searching criteria model and price , under model accordion there are three models, what I want to acheive is when a user clicks on that specific model , the page should run a query with respect to that click and show bind the results on the repeater of the left side bar, I know the query to get the results but I dunno how to get the value of that hyper link button, coz these buttons will be dynamic it can be 3,4 or 10. how will i get the clicked hyperlink valueso that I can run the query depending on the model selected.
i have a web page in which i place radio button list, when i select any radio button, on printing i get light color for selected radio button, how i get selected radio button dark colour so that it can visible easily..
I have a panel which has a repeater within it. Within the repeater I have a few controls. One of those controls is a Drop Down list which has an OnSelectedIndexChanged event. I can get this to fire without issue but I cannot find my DropDownList control within that repeater within the SelectedIndexChanged event . The repeater has an OnItemDataBound event and I can use the RepeaterItemEventArgs to find the control using e.Item.FindControl("ControlName") without issue but when that event occurs is NOT when I need to find the DropDownList.
What I want to do is have another control's Visible property be set to "true" when the value of the DropDownList meets a certain value. As far as I know I can only do this during the SelectedIndexChanged event and I can't change the signature of the event by trying to use RepeaterItemEventArgs.
