Web Forms :: Nested Dropdownlist Ondatabound => Bind Other Dropdownlist Fail
Dec 9, 2010I have a gridview with 3 nested dropdownlists in one cell on edit like this:To get the exact fields when the user clicks on edit I used the following code(yes it's messy)
[Code]....
The BLLOnderhoud is a class and the getReserveInfo is used to get the Model - Brand(merk) Information.Since the dropdownlists are nested in the gridview I can't call them directly and they can't call any of my functions.And this is the problem, when I change the dropdownfield Model the Auto field wich is the last dropdown(in the picture is a typo) should be binded like in the following code:
[Code]....
But the dropdownlist onDataBound event can't call any of my functions that are in my class.So my question is how can the onDataBound event of the second dropbox trigger a function? The only thing that the function has to do is to bind the 3rd dropdownlist
Forms Data Controls :: Unable To Bind Data To DropDownList In DetailsView
Sep 15, 2010I have a slight issue I awas trying to fix for 2-3 days, but nothing I try works.
The scenario:
DetailsView control in edit mode, I pass parameters to the SqlDataSourceProducts (edit.aspx?id=2) and the data source selects the appropriate data and fills in the DetailsView form.
Except two drop down lists. These two DDLs (DDL2 and DDL3) are dependent on the previous DDL (DDL1) in the DetailsView.
when the selected value of the DDL1 changes, DDL2 and 3 change their lists and get bound to the database.
The problem is: when I edit something from the database, DDL2 and 3 appear empty and when I update any other field and leave these, they get blanked in the database.
My goal is to set the selected value of DDL2 and 3 to the values in the database WHERE ID = QueryStringField="id".
I can go for not binding the data unless the field is changed, but does not sound professional and user friendly.
code:
The SqlDataSource used to select the parameters from the table and populate the DetailsView

The code of the fields that hold the DDLs in the DetailsView control

Forms Data Controls :: Bind Data From DataSet (DataTable) To A Selectrow DropDownList In GridView?
Nov 19, 2010I have a Gridview and two link button in that GridView , one link button click is to add edit row ( Edit ), one link button click is to select row ( Select ). I have a dropdownlist inside row which selected when i click link button Select in the gridview edit template, as of my business logic i need to show the dropdownlist only when the user clicks Edit button and when the user clicks Select button . That mean when the user clicks Select button then they clicks Edit button on the gridvview i should allow him to edit the dropdownlist (showing the value to the user through a label).
ASPX CODE
[Code].... C#
When I click Select link button , then I click Edit link button . They have errors : Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index" I don't know what error?. How to fix it
