Forms Data Controls :: How To Bind RadioButtonList SelectedValue
Aug 18, 2010
I have a FormView with an EditItemTemplate. In the EditItemTemplate I have a RadioButtonList. I want to populate the selected button from the database. My code looks like this (simplified):
[Code]....
The stored procedure usp_GetOrderDetails returns a char(1) column called "side" which can have values of 'B' or 'S'. If it's a B or an S I want to select the correct item in the RadioButtonList, radSide. Is this possible? I've done it for my Text boxes and dropDownLists on the same form OK, I just can't figure out the RadioButtonList.

I have Gridview inside that i have RadioButtonList,Which is working perfectly. It also bind correctly.
Problem is when user navigate page,the value which was slected in previous page is not apper again.
Gridview is enabled with paging.
I want to save data on SUBMIT button which is outside gridview. So when user clicks this button it should get ALL selectedvalue of radiobuttonlist inside gridview INCLUDING paging and save it to database.
I have tried following code on Button_Click but its not working properly.

I've two RadioButtonLists which pulls "fullName" and displays, the idea is for the user to select from RadioButtonList1 and RadioButtonList2 then submit the data.
If there is already values assigned from sql then there should be a selectedvalue for both controls. But I can't seem to get the controls to assign the selectedvalues.
I've a SqlDataSource, 2 RadioButtonLists and some code binding it:
[Code]....
Also when I go to select just one record from RadioButtonList and submit the data, it returns errors because it sees it as submitting null values.

I define the datasource in my c# code and I have a submit button which takes the value of the radiobuttonlist
asp:RadioButtonList ID="RadioPaidIdList" runat="server" DataValueField ="Label" DataTextField = "Label"
First time i click submit it returns an empty value. And next time i select a radiolist and click submit it returns a proper value.

I have a asp.net FormView with a DropDownList for the selection of a month. The FormView is data bound to an ObjectDataSource.
<asp:DropDownList ID="MonthsList" DataSourceID="MonthsListDataSource" DataTextField="Value" DataValueField="Key" SelectedValue='<%# Bind("OrderDate.Month") %>' Width="100" runat="server" />
I like to bind the selected value to the nested property 'Month' of 'OrderDate' as shown above. The property OrderDate is of type DateTime. The error I'm getting while binding to a nested property is:
A call to Bind was not well formatted. Please refer to documentation for the correct parameters to Bind.

This is driving me nutty... I have a gridview on a page. On the same page is a web user control with several public properties. Using the gridview's selectedindexchanging event, I try to set the user control property, but it's always null. Like this:
protected void grdPhysicians_SelectedIndexChanged(object sender, EventArgs e)
{
usercontrol1.ID = grdPhysicians.SelectedValue.ToString(); [code]....
If I write the grdPhysicians.SelectedValue to the page, I can see it's there. It just won't pass to the web user control.What I'm trying to do is have a master record form with child records in a web user control and just pass the selected record id into it.
protected void grdPhysicians_SelectedIndexChanged(object sender, EventArgs e)

Using ASP.NET 4.0 with C#.
I have a GridView and have sortable columns. When a column is sorted the GridView automatically selects the top row, however the SelectedValue is still representing the row before the column is sorted. The SelectedValue of the GridView only gets changed when a row is selected, but I want that to happen when the GridView is sorted.
For example if I have this in my code:
[Code]....
itemId is populated with the old SelectedValue not the new one after the GridView has been sorted.

My page has a gridview, and the gridview has a TemplateField called "Acciones" (Actions). The column Acciones has a ImageButton with CommandName "Select" and CommandArgument "Tutor". Thus, the GridView has controlled event "SelectedIndexChanged". The idea is that in GV_SelectedIndexChanged, I must to set DropDownList's SelectedValue property. But, the value seted in this function don't affect the rendered dropdownlist. The debugger talk's that the value is correctly seted, but the visual result don't.

Using VB.Net/Asp.Net 2008, web app with Master page.I have a content page where all of the content is wrapped in an UpdatePanel that uses a UserControl called GetEmployee.ascx that I created.
In the user control I have a listbox filled with employeeIDs for the DataValueField, in fact for testing to make sure I'm getting the ID I temporarily set the DataTextField to employeeID also. Anyways I keep getting "" error saying I have not selected anything even when I do so I put a breakpoint and set a watch to find out selectedIndex, value and item and nothing.
after the user selects an employee they should click on the "select employee" button so I have some code there to find out which employee was selected. I have events setup in the GetEmployee.ascx user control to get the value selected:
[Code]....
and I have a breakpoint and it hits the "selectedIndexChanged" event first so I put a watch there and see the following.
<WatchValues>
SelectedIndex = -1
SelectedItem = Nothing
SelectedValue = ""
</WatchValues>
why am I not seeing the selected value?

I'm populating a dropdownlist in a formview with a different datasource from the formview's. I need to set the selected value according to the value in the formview's datasource but I'm having a hard time doing that.
Here's the code:

DataSourceID="SqlDataSource1">

I'm using a FormView which has odsMain as the datasource. I am also using a dropdownlist which is being populated with objectdatasource odsddl.
I'd like to set the selectedvalue of the dropdownlist with the value contained in odsMain (the current record value for it). Is there any way this can be done?

How would I go about populating a textbox within a FormView with the SelectedValue of a GridView? I'd like to know how to do this with the GridView on the same page as the FormView or a GridView passing a parameter from another page.

I have a form that's being databound with a SQLDataAdapter. I have a DropDownList with a SelectedValue='<%# Bind("FieldName")%>' on it. I was wondering if there was a way I could remove this field and set it dynamically in the codebehind and still have it insert the value of this field with the SQLDataAdapter. The reason for this is because the control I'm using doesn't have a separate InsertItemTemplate, only an EditItemTemplate which serves both purposes, and I need this to dropdownlist to only be databound on Insert.
Right now it's looking like I'll have to stop using the SQLDataAdapter and Update/Insert the data in the codebehind, but I wanted to see if there was something I was missing just-in-case.

I don't know what wrong with my code. I always get empty value by using following statement(in GridView_SelectedIndexChanging event)
string IDTextValue=GridView1.Row[SelectedIndex].Cells[1].Text;// <-- My Column (which hold the key value) index is 1
How can I get correct value in code behind file? I used sqldataSource and GridView. I need handle some business logic in code behind file.

I have a drop down list inside a formview control's edititemtemplate and itemtemplate. The dropdown list is not bound to a data source. I am hard-coding the listitems for the drop down list. The formview is bound to a datasource. All I want to do is set the selectedvalue of the dropdown to what is in the record from the database. But I keep getting the error.
<asp:formview .....>
<edititemtemplate>
.... //some other controls like textboxes that are correctly bound and display the value from the datasource
<asp:dropdownlist ID=myddl runat=server cssclass=myclass selectedvalue='<%# eval("mychoice") %>'>
<asp:listitem value='0'>I dont know</asp:listitem>
<asp:listitem value='1'>Yes</asp:listitem>
<asp:listitem value='2'>No</asp:listitem>
</asp:dropdownlist
.....//rest of the edititem controls that display correctly.
</edititemtemplate>
Just for kicks, I added a textbox and set it's value to eval("mychoice") as well and it correctly prints 0,1 or 2. So, I know that there is no illegal value coming back from the datasource. It seems as something with the timing of events - when the listitems are getting bound to the ddl. The error I get is - "myddl has a selectedvalue which is invalid because it does not exist in the list of items".

I have a query that references many tables, however the main record doesnt necessarily have records in the other tables. In my formview itemtemplate, i bind the values of the query but I'm getting an obvious error when the value is null. This is what I'm trying to do: (the field is a boolean btw). These fields are hidden so I don't really care if it gets assigned a temp value or something.
