There is a button in the same page. While clicking on that button i want to display an alert message based on the selected radio list item using javascript. Some part of my javascript function is shown below
var RLCompareParameter = this.document.getElementById("<%= RLCompareParameter.ClientID %>");
if (RLCompareParameter.SelectedValue == "Forms") {
if (document.getElementById("<%= lbAvailableForms.ClientID %>").value == "") {[code]...
But the if(RLCompareParameter.SelectedValue == "some value") always false. i think there is no attribute like selected value for RadioButtonList control.
DataRow[] dr; dr = dt.Select("stepid = '1' AND placeid = " + Convert.ToInt32(h1.Value));so dt -- contains so many Rows from that i am going to filtering the data and add that row to the another DT - Finally bind the Dt to the Dropdownlist how to resolve this issue ?But it shows error :[Code]....

I am trying to validate that each radiobuttonlist has been selected. the radiobuttonlist is dynamically created from a sql database. The following line errors out "if (MyRadio[j].checked) {", the error is "checked' is null or not an object". The following is the code.
I'm posting this here because my question isn't really about the javascript itself but about the workings of the RadioButtonList control. I have a webforms application where a several radiobuttonlist controls are rendered dynamically from server side code. I want to also render an undo button that will clear the associated radiobuttonlist. I can get it to work fine using an image button that does a postback. However, I'd like to do it without the postback, waiting until the entire form is filled out before posting back via a submit button. I've been able to get it to clear the radio buttons via javascript. However, when I click submit to post back to the server, the server thinks the radiobutton is still selected. Here's a condensed version of the code thatrenders the controls.
[Code]....
At run time, the radiobuttonlists and their associated undo buttons are rendered just fine. If the user selects an option from a radiobuttonlist and then decides they didn't want to answer that question, they can click the undo button and in the browser the correct radiobuttonlist is cleared. However, when they submit, it still saves whatever value they had clicked before to the database. It's as if there is something else on the page that is holding on to the selected value in the radiobuttonlist even after the javascript clears the control itself.
If we are using ASP.NET Radiobuttonlist in our page it becomes a little difficult to find the instance of it through Javascript because it is rendered in a different way in the browser ( the code is reproduced below )
I'm at my wit's end when it comes to this. JavaScript definitely isn't my strong suit and I've been trying to google for a solution. Here's the code I have:

What I want to do is whenever you click a radio button on the Group1Most RadionButtonList, it will disable the corresponding radio button on the Group1Least RadioButtonList. The problem is I can't figure out how to select an individual radio button within the RadioButtonList.
I have a scenario where a RadioButtonList needs to be in disabled mode by default and then on some event on client side, say, when a checkbox is checked, it needs to be enabled.
But once I disable it from code-behind, the javascript part of enabling it doesn't work.
I have used a radiobuttonlist to enable/disable the textbox in Grid View. I did this using javascript onclick event.
[Code]....
It is working fine when the page get refreshed too.
[Code]....
Then in a scenario, I have removed the radliobuttonlist items (items 2 and 3) dynamically. For the first time when its loaded its working without flaws. After a page is refreshing due to any serverside events, the javascript to enable/disable textbox is not working.
[Code]....
I have verified the HTML file, the radiobuttonlist is loaded without the onclick event.
for the radiobuttonlist control, when I try to style individual buttons with 'span'I get a error, is there some way to style each button?
[Code]....
error is:
System.Web.UI.WebControls.ListItemCollection must have items of type 'System.Web.UI.WebControls.ListItem'. 'span' is of type 'System.Web.UI.HtmlControls.HtmlGenericControl
I have a radiobuttonlist inside a datalist itemtemplate and i need to bind the radiobuttonlist dynamically from database I have tried to bind it inside itemdatabound event of datalist but it the result is always duplicated according to the fields in teh database.
for more information:
the database has two columns one for questions and the other is for choices , for the first question with id lets say 1 there are 4 choices, when the radiobutton is binded the result appears to be 4 times duplicated ?
I am having crystal report nto my application. By using report document I am trying to export the report into pdf. But while trying that I am getting the exception "property evaluation failed" but the report is exporting. I want to know how to avoid that exception. So far I googled for that exception, I got some idea about calling response.end internally. But yet its not clear to me. I am giving some code sample here:
I've got a standard ASP.NET control, and I want to insert a C# variable's value into its Text property. HOWEVER, I can't do this via the TextBox's "Text" property (VERY long story) in the C# code; it has to be via the an embedded variable reference in the ASPX file.
Anyway, when I add the following script to my ASPX page at design time:
I have a code block that contains around 320 lines of code. Everything runs fine when i debug it until i reach the section that updates a sql datasource. I am using:
I have 38 lines of update parameters before i call the sqldscc.Update When i put a break point before the update parameters all the values are correct at the break point at the end all the values are "Property Valuation Failed"?. I'm not using any response.end, response.redirect or server.transfer
In my database table I allow null for the gender field. However, when the form is being edited, it gives me an error since the RadioButtonList does not have a match value for null. How do I get around this? Is there a way to have null value in the RadioButtonList control?
I am converting an old payment page from classic ASP to ASP.NET. The page includes three radio button options (credit card, purchase order, bill me). The old page uses javascript to enable/disable the appropriate input fields depending on which payment option is selected. For example, if the payment selection is changed from "credit card" to "purchase order", the credit card fields are disabled, and the PO number field is enabled.
I want to mimick this behavior using ASP.NET + server-side AJAX, so I created RadioButtonList for the payment options, and put all the data input controls (credit card number, purchase order number, etc.) within an UpdatePanel. The UpdatePanel has an AsyncPostBackTrigger with ControlID set to the RadioButtonList, and an EventName specified which tries to enable/disable the appropriate input fields depending on which payment option is selected. This doesn't seem to work because changing the radio button selection doesn't seem to fire this trigger.
Is it possble to utilize AsyncPostBackTrigger with a RadioButtonList control? If not can you suggest a way to handle this scenario for dynamically enabling/disabling form inputs?
Can someone explain to me the rules around what can and cannot be evaluated/inserted into markup using the <%# %> and <%= %> tags in asp.net?When I first discovered I could inject code-behind variables into mark-up using <%= I thought 'great'. Then I discovered that if such tags are present you can then not add to the controls collection of the page (that's a whole different question!). But <%# tags are ok.
Is there a way I can inject a code-behind variable or function evaluation into the page using <%# ?
Where can I find the expiration date of SQL Server 2008 Evaluation Edition? It's not in Help >> About and I don't see it in the server properties either.
