I'm trying to populate my form that is made up of RadioButtonLists, a Text Box and a DropDown via Code Behind. WHen I run it, the Text Box and the DropDown populate, but the RadioButtonLists do not. I'm guessing it has to do with the SelectedValue command, but I'm not sure what to use. Here is my aspx page:

Here is my code behind: [Code]....
I have a radiobuttonlist and what im trying to do is throw an error label when the user fails to select the button from the list. Im doing this in a switch statement in my code behind but I keep getting the error 'object reference not set to an instance of an object" but i dont get why is throwing that error since im saying to get the value of the list and if nothing is selected then throw the default case. here is my code: [Code]....
View 3 RepliesI have a radiobuttonlist in a details view. Databinding is happening in PageLoad (if not IsPostback), after a details view item is inserted, edited and upon clicking cancel when in edit mode.Everything works well except when clicking cancel which for some reason the radiobuttonlist appears as empty. The code is surely working because up till OnPreRender the radiobuttonlist contains the required items. However OnRender the list appears as empty.

I want to bind an ObjectDataSource to a property in my asp page and I want to do it in the page's aspx code, not in code-behind. I've already done it in code-behind, as follows:
[Code]....
I'd prefer to get rid of the ugly code-behind and just do this in mark-up. Something like
[Code]....
This gives me a run-time error: Cannot create an object of type 'System.Object' from its string representation 'SelectedBook' for the 'DataSource' property.Is there a way of doing this declaratively and not in code-behind? Further, what if what I want is to actually use a child property of the property in question? For example, if my Book object has a ReaderComments collection, can I databind to it decaratively in the aspx mark-up?

Is it possible to add the ListItem values in the code-behind within a for loop? If so, what is it? Here is my current code:
rblContentTypesGetAll.Items.Clear();
for (int i = 0; i < dt.Rows.Count; i++)
{
rblContentTypesGetAll.Items.Add(dt.Rows[i]["contentType"].ToString());
}
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 am using the jQueryUI buttonset on an ASP.NET radiobuttonlist. I need to get the selected value in server-side code when the page posts back. If I don't apply the jQuery buttonset, this is of course easy enough - just grab "SelectedValue". However, when I do apply jQuery buttonset, the selected value does not appear to be available on postback any longer. Is there any way around this, or do I need to get the selected value on clientside, and then pass it back myself?
<asp:RadioButtonList ID="RadioButtonList0" CssClass="ratingButtons" runat="server">
<asp:ListItem Text="Option1" Value="1"/>
<asp:ListItem Text="Option2" Value="2" />
<asp:ListItem Text="Option" Value="3" />
<asp:ListItem Text="Option4" Value="4" />
</asp:RadioButtonList>
$(function () {
$(".ratingButtons").buttonset();
$(".ratingButtons").click(function () { return false; });
});
Gridview not binding in code?

I have the following Dropdown List
[code]....
My problem is that some of the users that used to be in the list have left the company so we want to mark them inactive. When they are inactive they should not show up in the DDL to be selected to be assigned to. But there are existing records that they are already assigned to. If they are no longer able to be assigned their is a column called IsActive in the db that is set to 0. The Datasource filters for only == 1 when filling the datasource.
When it tries to render the control where a selected value is not in the list the Browser throws an error. I can not seem to find an event where I can intercept and set a value that is legal.
The solution I would like would be to add the listItem to the Control in the code behind then call the bind("AssignedTo") in the code behind instead of in the aspx page. This way linq would still handing the update of the DB record for the update event.
I have Table named PRODUCTS , that have 4 column productid, productprice,productname & discount( type numeric(18,0)) .. i am using datalist with itemtemplate that have 4 label to display all ..
I am binding datalist on pageload, now i want that Label4 with "discount" should only visible for those product that have discount , otherwise it remains hidden,
Problem in my code is that when i run it , label becomes invisible for all products whether they have discount or not. Here is my code i am using for it:
ds1 is my dataset
foreach (DataListItem item in DataList1.Items) {
for (int i = 0; i <= ds1.Rows.Count - 1; i++) {
double[] arr = new double[ds1.Rows.Count];
double temp = double.Parse(ds1.Rows[i]["discount"].ToString());
arr[i] = temp;
Label lbl = item.FindControl("Label4") as Label;
if (arr[i] == 0)
lbl.Visible=false;
} }
I select a item from gridView and trying to show/update/delete in From view. In Form View I am using the dropdownlist filling it in Code behind. Then i bound the list. But the problem is it is not showing the slected value. Here is the code

The issue is that the list retrieved from the LoadLists method is null when passing to the LoadList method where the datasource is bound.
I have a grid view which I am binding it through my .cs file code:
I need to hide a column, From the Below code I am able to hide the column but not the header and footer design.
So how can I hide my column when I dont have any columns in my gridview (I mean in .ASPX page)
MyCode:
[Code]....
.cs Code:
protected void Row_Grid(Object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
e.Row.Cells[9].Visible = false;
}
}
i have a grdidview control on the .aspx page and i am trying to connect dynamically from code behind and bind the gridview but somehow it throwing me an error... what is wrong with this code?
LinqDataSource LDS_POReport = new LinqDataSource();
LDS_POReport.ContextTypeName = "DataContextDataContext";
LDS_POReport.Selecting += new EventHandler<LinqDataSourceSelectEventArgs>(LinqDataSourcePO_Selecting);
this.gvReport.DataSource = "LDS_POReport";
//this.gvReport.DataBind();
Update:
after i update the code to this.gvReport.DataSource = LDS_POReport;
it works fine but when i try to sort i get this error:
The GridView 'gvReport' fired event Sorting which wasn't handled.
i added this but no effect.
LDS_POReport.AutoPage = true;
LDS_POReport.AutoSort = true;
Currently,below is my code.
protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e)
{
SqlConnection conn = new SqlConnection("Data Source= E\SQLEXPRESS;" + "Initial Catalog=k;Integrated Security=SSPI");
SqlDataAdapter adapSel;
string mySQL = "select column_name from information_schema.columns where table_name='examtimetable' '" + dd_list + "'";....
I receive an error "Incorrect syntax near 'System.Web.UI.WebControls.DropDownList'."
I have a details view in asp.net which I am dynamically replacing some of the controls using code behind (e.g. converting some text boxes to dropdowns). My problem is that I am unsure how to bind these to the field from the database on postback. I.e. I am trying to find the code behind equivalent bind('currency');
I can populate the dropdown with the current value from the database but cannot find how to save a new value on updating the detailsview.
What's the difference between binding for example a column called ("Name") in both cases ? and is there's any performance difference ?1- Assigning the data in the mark-up
<asp:Label ID="Name_Lbl" runat="server" Text='<%# Eval("Name") %>' ></asp:Label>
2- defining a control object for every control inside the repeater ItemTemplate and find it and then assign the data in the column "Name" to ite.Item.FindControl("Name_Lbl")
May I know what is the diffrence between static binding and dynamic binding and which binding is used in
1)Virtual Functions
2)Abstract Class
3)Function Overloading
4)Operator Overloading
5)Fuction Overriding
6)Delegates

ViewState is active and I have a RadioButtonList with DataSourceID to LinqDataSource.If I postback and cause event SelectedIndexChanged, I can read the SelectedValue property, but if the postback is caused by another control, SelectedValue its always empty...Note if I turn ViewState off, works fine, SelectedValue has always a non empty string...
View 3 RepliesI am creating a wizard with a radiobuttonlist inside it. There are no style sheets being applied and I have the RepeatDirection set to Horizontal and the RepeatColumns set to 5. I have also tried changing the RepeatLayout from Table to Flow and nothing works. I want the radiobuttonlist to show up horizontally, but it keeps showing up virtically. Let me rephrase that. In the Design view in VS2010 it looks fine. However, when I view the live web page, the darn thing keeps going virtical.

I want to be able to display information about each rate pulled, mainly: a description for the user, the rate or charge amount, hidden from the user I would like to save the estimated date of arrival and shipping method code.
Right now i'm using a RadioButtonList to display the data, but with a name/value pair I can only do so much (unless I wanted to really hack it up and make the value of each list item comma delimited or something like that to be able to store all that data). There can be multiple rates shown depending on the number of shipping options rates are being pulled from. Is my only other option to use a repeater or are there any other clean options?
