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.
View 6 Replies Ive been strugglng with this one problem for a while now. I have an application as: SelectCommand="SELECT [CategoryID], [Name], [UserId] FROM [Categories] WHERE ([UserId] = @UserId) ORDER BY [Name]">
<SelectParameters>
<asp:QueryStringParameter Name="CategoryID" QueryStringField="ID" />
</SelectParameters> [code]....
the dropdown list control will populate values from the database but when i live those 2, it won't populate any value from the database. When i remove only the
<asp:QueryStringParameter Name="CategoryID" QueryStringField="ID" />
</SelectParameters>
and live ([UserId] = @UserId), i get the error : Must declare the scalar variable "@UserId".
I am using:

This solution doesn't work though. It doesn't leave the option of choosing anything from the list. Plus I would like it if it were a Radiobutton instead of a Dropdown. The field in the database is varchar(50).
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 ?
This was working fine and then I was tinkering around and I can't figure out what I did to break it. When I stepthrough the debugger, the for each stmt cannot read values from the radiobutton list or the textbox, it only show "" for each. I double checked the id names between the code behind and the markup.

I try to set the selection in the radiobuttonlist accordingly to data retrieved from the database.
This is not working (the mydata.gender contains "Mail")
mygender = myfatality.gender
I have a number of controls on a form i.e date pickers text boxes and dropdownlists. Firstly i need to set up some validation rules on the search button click event so if one control is populated then another needs to be and others shouldn't be etc etc
Then based on the values i need to return a dataset to the gridview showing all the records where the criteria meets all the values. I just wondered the best way to do this... i.e should i use validators to test for the rules(they may be too complex though). Should I just create a string and pass it as filter to the full dataset or use a stored proc and pass the string as the where criteria? This would mean a dyanmic proc so I'm not sure if there are any benefits as it won't cache on the server .
I'm trying to populate a datasource for a dropdownlist (which is actually in an insertitem template field within a detailsview on the same page) with a selectedvalue from a gridview. When I select a row in my Gridview 1, I get the "no value for a required parameter" message. ( and I have tried various alternatives... setting the selectedvalue of the grid to a variable... setting the selected value of the grid to a textbox nothing seems to work. It seems like this should be a pretty simple thing. I think I'm missing something obvious! Here is my code:

I'm stuck with a problem to populate a DropDownList control with values from the database using item field template in read only mode. since I'm new to ASP.NET. Below is the code and the error I'm getting:
'PictureReadOnlyCategories' has a SelectedValue which is invalid because it does not exist in the list of items. Parameter name: value Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.ArgumentOutOfRangeException: 'PictureReadOnlyCategories' has a SelectedValue which is invalid because it does not exist in the list of items. Parameter name: value
The code for this is :
<asp:SqlDataSource ID="categoriesDataSource" runat="server"
ConnectionString="<%$ ConnectionStrings:ConnectionString %>"
SelectCommand ="SELECT [CategoryID], [Name] FROM [Categories] WHERE ([UserId] = @UserId)">
<SelectParameters>
[Code]....
I have an application as: SelectCommand="SELECT [CategoryID], [Name], [UserId] FROM [Categories] WHERE ([UserId] = @UserId) ORDER BY [Name]">
</asp:SqlDataSource>
Pick a category: <asp:DropDownList ID="categories" runat="server" AutoPostBack="True"
DataSourceID="categoriesDataSource" DataTextField="Name" [code]...
When i take away the <SelectParameters>
<asp:QueryStringParameter Name="CategoryID" QueryStringField="ID" />
</SelectParameters> and ([UserId] = @UserId), the dropdown list control will populate values from the database but when i live those 2, it won't populate any value from the database. When i remove the <asp:QueryStringParameter Name="CategoryID" QueryStringField="ID" />
</SelectParameters>,and live ([UserId] = @UserId), i get the error : Must declare the scalar variable "@UserId".

I am somewhat new at C# so forgive me if I have something listed wrong. This is what I got:
I am working on a school project designing a car dealership website. I have an inventory list that allows you to edit any car in the inventory. When you click on the edit button it takes you to the edit page and populates the controls with selections from the database. I have an options table that stores the VehicleID and Option ID. When the page loads it fills all the DropDownLists for the vehicle info with the data and selects the correct item according to the database selection but the CheckBoxList does not select the items that are on the Options table. I checked the query in SSMS and it returns the correct data. I have stepped through the method and it works till the "(currentCheckBox != null) if statement. It doesn't throw any errors but it also doesn't select items when the page renders.
I thought it might have been something with the page life cycle since databound controls don't render until the end but the DropDown's I have fill and selects the correct item according to the database.
I need to create a gridview to show in each row, some columns from the SQL Database, and in other columns I want to have text fields, buttons and DropDownLists!
This GridView is to display the users of the web application.
First columns are name, email, and other stuff that can be easly queried to the SQL database.
Then, I need to have a column with one text field, and some buttons, in the text field the AdminUser should be able to insert some text and then click in a button to change the email/pass from the user represented in that line.
The other field I need, is a DropDownList that shows by default the Role of the user of the row, but we can choose another role and apply it, with a button in the same cell!
If I create a code-Behind query and populate the GridView, I don't know how to insert textbox's, button's, DropDownList's
If I create the GridView with the wizard, I can had TemplateFields, but I don't know how to associate the query with the BoundFiels where should be the name/email of the users.
Other problem, is that, even If I get to construct my GridView with sucess, How can I reference the row? So I can apply the changes?

How do i link 2 pages, ie., on click of a button on first page should take me to second page.

I'm currently developing an ASP.net application w/ VB as the code behind. I have a page that shows all the user name currently assigned to the system. The problem now is that the page does not communicate directly to the database. Instead, I use HTTPrequest to get all the user names from a different sever. Now I want to populate the listview control w/ the response that I got (and not directly from the database).
View 3 RepliesI would like the user to select an item from a drop down list. Next to the drop down is a textbox or label control. From the ddl selection I would like to populate the textbox or label from a database with a corresponding field from the database the dropdownlist was populated from. On selectindexchange event I can populate the textbox with the Unique id from the value, but I need to input a different field into the textbox. Can I use some sort of variable to assign the Textbox.Text = ?
