I have a page in my website where there is very little code-behind. I only have two lines of code in Page_Load() and the rest of the code is declarative ASP.NET code. I have a FormView control which uses a SqlDataSource to get some order information. The SqlDataSource calls a stored procedure called usp_GetOrderDetails, here's the code for the SqlDataSource:
[Code]....
<truncated>
What I want is to grab the screenshotId from the SqlDataSource when the usp_GetOrderDetails stored proc gets called and populate it into a field on the page called screenshotId. I then want to use this screenshotId to get an image from the database based on Id. populating the screenshotId field. How do I do this - do I need to have something like OnDataBound or something like that?
Something should be wrong alert comes. My scroll page function ..

I am building a page that requires a ComboBox that retrieves its data using ajax. We are currently using the AutoCompleteExtender with a webservice, but my requirement demands that I have default values in the dropdown and thearrow button to the right. Any help would be greatly appreciated. I have been struggling trying to convert the AutoCompleteExtender to act more like the combobox and visa-versa and it is a total pain.
Nested GridView Control returns "Object variable or With block variable not set" when outer GridView returns rows.
The Nested GridView Control works as long as the outer GridView returns rows, the following code works: [Code]....
Object variable or With block variable not set.
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.NullReferenceException: Object variable or With block variable not set.
Source Error:
Line 118: If e.Row.RowType = DataControlRowType.DataRow Then Line 119: Dim myStatus_ID As SqlDataSource = CType(e.Row.FindControl("sqlDeviceStatusAssign"), SqlDataSource) Line 120: If Not e.Row.DataItem("Status_ID") Is Nothing Then Line 121: myStatus_ID.SelectParameters(0).DefaultValue = e.Row.DataItem("Status_ID") Line 122: End If
I have tried checking for IsDbNull and checking to see if a label exists in a given row. This code *If Not e.Row.DataItem("Status_ID") Is Nothing Then* appears to do nothing.Same with the following:
*Dim localLblItemReference As Label = CType(e.Row.FindControl("lblItemReference"), Label)
To further clarify my question above, I am looking for a method to detect e.Row.DataItem("Status_ID") is nothing/null due to the outer GridView returning 0 results in a query.I have a (Outer) GridView Control with another GridView Control inside of a template field with it's associated SqlDataSource control.
In the "Protected Sub GridViewReport_RowCreated", I provide the Select Parameter for the associated SqlDataSource with the DataItem row value.When the (Outer) GridView Control does not return any rows, the "e.Row.DataItem("Status_ID")" throws a:
Exception Details: System.NullReferenceException: Object variable or With block variable not set.

I want to get data from the database and display it in gridview. The gridview should be editable. Meaning the user can add, edit and delete items/rows in the gridview. Everytime the user adds/updates/deletes an item, the gridview is also updated. However, these changes will only be saved to the database once the Save button is clicked.
I'm trying to make a dropdown list with data available based on the users login name. Heres what I have as my SQL Query in the SQLDataSource:
SELECT Client_Name, Client_ID FROM Client WHERE (Client_Name LIKE '%@Client_Name%')
So say if the login username is "User1" but the database client name is "User1 Steel" I want the dropdownlist to pull "User1 Steel" as the display and Client_ID as the value from the dropdown list.

I have a page where I will insert all the data into the database. The page where I'm having problems is when I select an item from the checkboxlist it only displays one item. The data which is displayed is only the one that was inserted with one selected item from the checkboxlist. The following code is the page I'm using to try to retrieve the data from the database. I am trying to do is when a user selects the first, second, or third, or fourth item. The corresponding data appears in the gridview. In my current code, the record which has one item selected appears. If the user has more than one selected it does not appear. It comes up as empty. Is there a way I can do it?
