Objectdatasource onupdating gridview
We need to generate Item Template and Edit Item Template dynamically for each field of the table, plus a field for buttons required for each command.The former lets to specify how an item will look like in normal mode (usually displayed in labels) while the later lets to specify how an item will change when it is put into Edit mode (displayed in text boxes).The following listing shows how to create template fields at design time.It shows that we must know number of fields and their name in advance to create their templates. Listing 1 keeps an indicator in string form for a type of information within a template field i.e.Problem in placing Drop Down List in the Grid View and preseving the Selected Value is one of the frequently asked question I have found on the different forums.In this article, I have shown how to achieve this functionality.As my Drop Down List has been bounded before Grid View Row so Grid View will be able to find the Selected Value specified in the Drop Down List and that selection will be maintained as you can see in the above picture.Binding Radio Button List in the Grid View, specify the Selected Value as the way we had sepcified in case of Drop Down List box.
I tried it but my code failes, i tried different things but nothing works. I get folowing error: Object Data Source 'Object Data Source1' could not find a non-generic method 'Update Transactie' that has parameters: Naam, Omschrijving1, ID_SR, @ID_SR, ID.

I get folowing error: Object Data Source 'Object Data Source1' could not find a non-generic method 'Update Transactie' that has parameters: Naam, Omschrijving1, ID_SR, @ID_SR, ID. I tried for one week now but i don't get it to work, can you help me please?!! Apart from Drop Down List, I have also shown how to keep other forms control like asp: Check Box, asp: Text Box, asp: Radio Button List in the Grid View and preserving the selected value that is coming from the database.To place the Drop Down List in the Grid View, you will have to use To specify the default value coming from elsewhere of any of the forms server control, you will have to use single quote ( ' ), instead of double quote ( " ).If you will specify double quote, you will get following error.event and found the Drop Down List for that particular row and bounded the Drop Down List box.Well, you can do that however in that case you will not be able to maintain the default value for that record that is coming from the database which I have specified using event fires when the Grid View Rows is actually being bounded and at the time of binding Grid View rows, the Drop Down List items is not bounded so there is no way you will be able to get its items and the Selected Value will complain that it couldn't find the item to select.
