Forms Data Controls :: Radiobuttonlist Inside Datalist Itemtemplate/bind The Radiobuttonlist Dynamically From Database
Feb 2, 2011
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 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.
In the website I'm building, I have a form that allows new users to register. Part of this page has mandatory address fields, and I use a postcode lookup field which returns a SuburbID and FullSuburbName (Suburb, State & PostCode) to a RadioButtonList inside an UpdatePanel.
[Code]....
I then handle the insert process in codebehind, and all this works perfectly on my New Account page.What I'm trying to do now, however, is replicate this functionality in the Edit Template of a FormView on my Manage Account page. The idea being that the user can view their current details in the ReadOnly view, then switch to Edit view to change their address (amongst other details of course). When the FormView changes to Edit mode, it should display the user's current PostCode in the textbox, and the RadioButtonList should display the available Suburbs for that PostCode, with the user's current SuburbID as the initial SelectedValue. If the user changes the PostCode and hits search, this refreshes the RadioButtonList with the new list of Suburbs, and once they have selected a new SuburbID this should get written back to the DB with the rest of the form (when they click Save I mean), using the SQL Data Source Update element. However, I simply cannot get this to work inside the FormView Edit Template and
So far, I have tried to handle the FormView's ItemCreated event and populate the RadioButtonList with the Suburbs that match the user's current PostCode, but if I do this with SelectedValue='<%# Bind("SuburbID") %>' in the RadioButtonList, I get the error "Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control."If I then change it to have the SelectedValue populate from the codebehind, this works on the initial switch to Edit mode, but when the user changes the PostCode and hits search, I get a different error "'rblSuburb' has a SelectedValue which is invalid because it does not exist in the list of items."My thinking was that rather than binding the RadioButtonList I would just add the new SelectedValue in the SQLDataSource_Updating method, but it doesn't seem to like that either.
I need to bind data from an SQL Select Statement into a RadioButtonList and have not been able to come up with anything that works.
[Code]....
In my VB code behind I have a select statement that retreives the information from the database and randomizes the answers, but I am unable to get this populated into my RadioButtonList.
I have a grid and on each row of grid i generate a radiobuttonlist with 2 items dynamically in rowdatabound. On the save button event i want to access the data of the row and save the data in DB with which ever radio button is selected.I tried different things but all in vain. I tried to use hidden field so that whenever any radio button is selected in a row then in javascript i will update the hidden field but user can select multiple rows so this is not a good solution.
Here is my code of dynamic radio button list generation in rowdatabound event.
I want to present a list of delivery options to end users which will be in 3 columns - service description, radio button (to select) and then the price of the service. Also I want to auto postback when the user selects a service from the appropriate radio button - e.g. :
[code]....
I have set this up using a repeater control and stand alone radio button, plus literals to display the text elements all within a tabular structure which looks OK. I have actually overcome the issue where by default you can select all radio buttons using the prescribed javascript fixes I found when searching. This way offers me control over the formatting which is important.
However it does not seem that intuitive to pickup the selected value of the radio button this way, especially with the auto postback - I am having issues trying to access the selected radio button to interpret what the user wants.
It would seem much more appropriate for a RadioButtonList but I can't work out how to override the default formatting, and also how to insert extra table columns for the price etc to keep it all nicely formatted.
So either I need to crack the interpretation of the current setup or to find out is there a way to hijack the default setup of 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.
im having a quizz (a question and multiple answer related to the question) , i use an asp repeater to display the questionand a nested radiobuttonlist inside the item template for the related answer:
[Code]....
I do bind the the radiobutton on itemDatabound, i need to store the answer selected by the user, for that i used the following method:
[Code]....
but the rptAns referring to the radiobuttonlist (there is only one quiz at a time), the selectedindex always remain at the first index even when the user does change the selected radio button.i have made a check when on item databound to see if the page is a postback before opulating the radiobuttonlist.
I placed a RadioButtonList inside a Formview control.And from DataBound event handler oformview ,RadioButtonList is binded to the datasource .Now my problem is after selecting a value from radiobuttonlist and I click any button,the radiobuttonList get unchecked and lose the selected value .How can I avoid this.
New to asp. I'm trying to figure out how to populate a radiobuttonlist with selections from a table in a database. I honestly have absolutely no idea how to do. There will be different products in the database that need to be pulled to different radiobutton lists.
I have a radiobutton inside an itemTemplate in datalist , and i'm binding this radiobutton dynamically from database, the problem is that all the radiobuttons generated are selectable at the same time which is wrong. (Multiple radiobuttons selcted at the same time)
I have ASPxDataView and ASPxRadioButtonList within item template. i also have two SQLDataSource's (first fill ASPxDataView, second ASPxRadioButtonList). They are using other database tables connected with the foreign key. Is there any way to pass parameter to my second sqlDataSource (id) to fill RadioButtonList property ? i mean select * from TABLE2 where id = @id ; (@id is a value from TABLE1 which is a value of column returned by first sqlDataSource)
Very new to ASP.NET (using C# behind) and am having trouble figuring out the following scenario. I have a DataList that is populated (code below) and wanted each cell to be clickable. When the cell is clicked I wanted to know the unique ID for that cell. In my code behind, my OnClick method looks like this:
[Code]....
However I never get there. It seems as if the linkbutton always refers to some javascript callback function and just reloads my form. Am I using the wrong control for what I want to do? From this click I want to look up more information from the Key (will roll up the datalist or set visible to false, then supply the new data on the same page)DataList:
i need to use linkbutton(Go for more detail)......on that link button i need to check session values .if session variable on that page exist..it should redirect to a different page...but if session on that does not exist..it should be redirected to a login page.....my link button is within datalist control....
i m using following code in link button.....but somehow is not working..
