Selecting Radiobuttons Populated Within Asp.net RadioButtonList With JQuery
May 21, 2010I have been tinkering around with what should seem a pretty straight forward task even for a jQuery newb as myself.
I have a radiobuttonlist control bound to a collection:
<asp:RadioButtonList ID="radBtnLstPackageSelector" runat="server"
CssClass="PackageS">
</asp:RadioButtonList>
My form does have several other controls of the same type; Now, the challenge is to select and wire up a on Click event for every radiobutton from the radBtnLstPackageSelector.I have tried several approaches such as:
var results1 = $(".PackageS").children("input");
var results1 = $(".PackageS").children("input[type=radiobutton");
var results1 = $("table.PackageS > input[type=radiobutton");
Web Forms :: Dynamically Populated DropDownList Not Working
Jun 3, 2010I have two drop down lists on my page. One (DropDownList A) has the values preset by me. The other (DropDownList B) has its values filled by a database query if a button is pressed. Each of them have AutoPostBack set to true. Each of them have corresponding onselectedindexchanged functions. DropDownList A works fine. When I change it, I want it to turn itself invisible. It does. DropwDownList B is not working. When I select something, it does the postback but the selected item is reset and the onselectedindexchanged function is never called. I feel like this is a problem I've solved in the past, but it's been 3 years since I programmed ASP.NET. All this is done in C# by the way.

Web Forms :: Dynamically Populated DropdownList Value Not Seen When Button Pressed?
Sep 27, 2010Sample Code.
<asp:DropDownList ID="MediaTypeDDL" Width="306px" ToolTip="Select Media Type" runat="server"></asp:DropDownList>
<asp:DropDownList ID="MediaFormatDDL" Width="306px" ToolTip="Select Media Format" runat="server"> </asp:DropDownList
<asp:Button
ID="btnUpload"
runat="server"
OnClick="btnUpload_Click"
Text="Upload"
/><br
/>
protected void btnUpload_Click(object sender, EventArgs e)
{
String strMediaFormat = MediaFormatDDL.SelectedItem.ToString(); // Not seeing value here!
}
Item Selected in MediaTypeDDL determines values in MediaFormatDDL. I'm using Javascript to populate MediaFormatDDL. This is working. I now select the item I want from MediaFormatDDL. That works The problem I'm seeing occurs when I press the button to save the values from
the screen. I don't see the Item I selected from MediaTypeDDL. All the other fields are okay. This must be someThing simple, but I'm not seeing it.

View 1 RepliesWeb Forms :: CheckBoxList Dynamically Populated How To Retrieve Values During Postback
Apr 30, 2010I have a form with 2 sections. The first one contains some radio buttons. The second one contains a checkboxlist. When we change the selected radio button then it modifies the elements in the checkboxlist. For this I setted the radio buttons with autopostback, and in the code behind (in OnLoad) I populate the CheckBoxList depending on the selected radio button.
This work fine.
The problem is that I also have a button at the end of my form which post the data of my form in another page (with PostBackUrl). Then in that page I would like to retrieve the values of the checked checkbox. But I can't find how to do that. In the Request.Form I don't see anything.
I searched on the web but I didn't found really a solution.

Web Forms :: Dynamically Populated Listbox Always Return Selected Items As False?
Mar 10, 2011I have the following code which simply gets data from a table and populates the questions_lb listbox with items. I have a button on the page, which when clicked, should write (on submit) the selected state of each of the items. The code below writes the text values of each of the items fine however it always writes the li.Selected as False even though i have selected items from the list. Note that you can select Multiple items from the list. Does anyone have a clue why its not writing 'True' for an item that is selected on submit?

Forms Data Controls :: Dynamically Populated Dropdownlist Inside Gridview
Mar 28, 2011I have a gridview which contains a templatefield. Inside this is an ImageButton and a dropdownlist. This is all created in the aspx page, although the ddl list items are populated in the RowDataBound event in the vb page. When i change the selected item in the drop down list and hit the imagebutton, the selected item is not maintained after postback. Instead the first record is displayed in the dropdownlist. I have wrapped an If Not Page.IsPostback around the datasource and databind's but this doesn't help. I have tried enabling viewstate in all areas on the page too, but still nothing. The list items for the ddl must be created on RowDataBound also. As far as I am aware, my ddl is not really dynamic, its just the list items which I add in the code behind which are classed as dynamic.
View 11 RepliesWeb Forms :: Retrieving Item Values From A Dynamically Populated CheckListBox During Page_Init
Jan 15, 2010i have a checklistbox that is databound during Page_Init in an
If (!Page.IsPostBack)
block. the user can then check off certain values, and click an asp.net button which posts back the form and renders a crystal report on the same page.
i need to be able to determine which items were checked in the control so that they can be used as parameters in the crystal report. rendering must be done during Page_Init.
the checklistbox object is on the page during design time; only the items are dynamic.
i tried using the Request.Form object during Page_Init to obtain the checkboxlist's items but either i didn't code it correctly or it can't be done that way...
can the checkboxlist items' values be obtained during Page_Init, and if so, how?
