Web Forms :: How To Access The Selected Item From The Radio Button List
Jan 11, 2011
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?
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');.....................
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 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
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 list with 2 sorts of items. Items that have actual values (1,2,3,4 etc) and items that are like group headings so all their values are set to 0. If someone decides to select a group heading - which has a value of 0, is it possible to redirect them to my 'Select an item' item which has a value of ""?
If worse comes to worse, I can just reconstruct the entire list, although if possible I'd like to avoid it.
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.
n a form I have multiple group of controls which are grouped using validation group property. I want to assign validation group to asp.Button dynamically on client side using javascript on the base of item selected in drop down list.
Here is JavaScript which I am using, but it is not working. It shows validation group undefined but actually a default group is defined.
<script type="text/JavaScript"> function NextClicked() { var _ddlStatus = document.getElementById("<%=ddl.ClientID%>"); var _selectedIndex = _ddlStatus.selectedIndex; var _btn = document.getElementById("<%=btnNext.ClientID%>");
alert(_btn.ValidationGroup); // here in messge it shows undefiend, yet I have defiend a group in button as default.
if (_selectedIndex == 1) { _btn.ValidationGroup = "G1"; } if (_selectedIndex == 2) { _btn.ValidationGroup = "G2"; } }
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..
Clicking the label of a drop down list, re-sets the selected value to the first item in the list. This has a history of causing data entry problems when users accidently click on the label.
In the below example ddlContactType has a selected value as 'PRIMARY' and whenever i click on the lblContactType Text, the dropdown box Selected value is changing to "Select One" Text.
How to prevent this one. It should be on PRIMARY Only.
Here when i click on button it insert all data into table but it didn't insert my selected item from dropdownlist it insert select city that i define in page_load
DDL1.Items.Insert(0, new ListItem("select city", "0"));
And when i delete this code from page load it insert in table first row of my table it didn't insert my selected item from dropdown list.
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 radio button.i need to select only one item through out gridview i have written code that is working fine but that is giving problem in paging i am displaying gridview with 5 records per page.in first page i am able to select only one item but if i move to second page here also i am able to select only one radio button in this mean time if move to first page in that page also radio button is in selected mode .How can i make only one radio button selected in through out gridview and How can i get paging data from gridview(if i select 3rd page value and i moved to first page in that situation i need to get get that 3rd page value aslo ).
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 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?

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.
