C# - How To Call Function When The Selected Index Changes In Radio Button List
Mar 21, 2010
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'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'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..
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?
create List of dynamic asp:Label, asp:textbox and asp:button when asp:dropdown selected index changed Dropdown List - ddlLang - English, Italian, French, German
If English is selected from ddlLang Create new asp:Label, asp:textbox and asp:button. If French is selected create another new asp:Label, asp:textbox and asp:button. In the same way so on.... and when button submit clicked get all dynamic text box values and label values to Save to DB.
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 an aspx page with two buttons, one of the buttons has an OnClick attribute to a function that should be run when clicked. When the other button is clicked there is an if statement checking if the page is a postback, if it is then I run some statements that need to be run when that button is clicked. That postback button works fine. However, the other button, when it's clicked the function it's supposed to call never executes, and the statements inside if (Page.IsPostBack) get executed instead. What can I do to fix this? Is there a way to make the button that calls a function not do a Post back?
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.
Here i write down some code but its just select 2 item of the each radiobuttonlist and checked all checkboxlist.
i have a view wich gets in its model (among other things!) a string with the name of partialView to be rendered in a certain div.
well, in that partial view there are two radion buttons, with the same name but diferent id's and values.
when i submit the form in the view, wich also has the partialView controls (radio bts), in the respective controller i get inside a formcollection an item with both values of the radio buttons,
my question is, how can i find wich one was selected in the view?
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 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'm trying to sort records in the gridview right after a radio button is selected. My approach is with the dataview, but because the dataset variable doesn't survive a round trip to the server, I don't know how to make this happen.
Public Sub GetCustomers() db.RunProcedure("usp_customers_get_all") db.doSort(radList.SelectedValue) gvCustomers.DataSource = db.MyView End Sub Protected Sub radList_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles radList.SelectedIndexChanged If radList.SelectedValue = 0 Then db.doSort(0) gvCustomers.DataSource = db.MyView End If If radList.SelectedValue = 1 Then db.doSort(1) gvCustomers.DataSource = db.MyView End If End Sub Public Sub doSort(ByVal strIn As Integer) If strIn = 0 Then MyView.Sort = "lastname, firstname" Else MyView.Sort = "username" End If End Sub Public Sub RunProcedure(ByVal strName As String) Dim objConnection As New SqlConnection(mstrConnection) Dim mdbDataAdapter As New SqlDataAdapter(strName, objConnection) Try mdbDataAdapter.SelectCommand.CommandType = CommandType.StoredProcedure Me.mDataset.Clear() mdbDataAdapter.Fill(mDataset, "tblCustomers") MyView.Table = mDataset.Tables("tblCustomers") Catch ex As Exception Throw New Exception("stored procedure is " & strName.ToString & " error is " & ex.Message) End Try End Sub
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 am using three check boxes. If i click first radio button list item, the first check box need to show. In the same scenario for another two radio button list items and checkboxes. How can we done in javascript. i call it the onclick function and put it node value for this condition but when in alert the node value is giving null. this is my java script code.
var uxNotClearedObj = document.getElementById('uxOHCNotCleared2'); //alert(uxNotClearedObj); var uxPendingObj = document.getElementById('uxOHCPending2'); // alert(uxPendingObj); var uxClearedObj =document.getElementById('uxOHCCleared2'); //alert(uxClearedObj); var rdPendingObj = document.getElementById('rdPending'); // alert(rdPendingObj); var rdClearedObj = document.getElementById('rdCleared'); var rdNotClearedObj = document.getElementById('rdNotCleared'); // alert(rdClearedObj); var rdHealthClearedObj = document.getElementById('rdHealthCleared');.....................

[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.

On the onchange event getting the new selected checkbox, this with jquery.
The checkboxes are located in the following div :

This all located in a form, when I will find out the selected radio on change I will post the form and use the value of the hidden field to know the selected radio button. Nothing really difficult.
