Rowupdating which wasn t handled

As a new comer to coding, I am finding this challenging. Since the issue is related to data filtering then the problem might be with the value of the parameters you pass in into your sql WHERE clause.

Principal; // here is the security namespace you need using System. I think I maybe missing some piece of Visual C code or it is not being linked properly somewhere.

rowupdating which wasn t handled-24

For the Template Field, we do know the ID of the control since we specified it in the markup, so we obtain a reference to it by calling Find Control on the appropriate row of the Grid View.

The Grid View Row is the naming container for the Text Box in this case, so we need to call Find Control on the appropriate row, but we do not need to call it on the specific cell.

The Grid View 'Grid View1' fired event Row Deleting which wasn't handled.

When I say manually databinding I mean not using a data source control specified as a Data Source ID, but rather setting the Grid View’s Data Source equal to the appropriate data object and calling Data Bind.

) If possible could you please tell the cause of this and what should be done to rectify this ? HI, You need to add reference to namespace of System. NET Framework 3.5 to 4.0 and the error was resolved. I am about done with this now, just a last query: The data in the gridview needs to be displayed when the user clicks the (Find) button. This would mean that after you query the database with the filter parameter you fill your Data Table (for example) with the results and bind it to your gridview.

I am getting this error on Datatable- Error 1 The type or namespace name 'Data Table' could not be found (are you missing a using directive or an assembly reference? Refere msdn ( for detailed explaination Thanks, Nirav HTH Thanks Vinz, I changed from . Here's a step by step example of binding Grid View with data from Data Table: NETvinz/archive/2009/02/19/binding-gridview-with-data---the-ado.Just modify your sql select query based on your requirements. Keep in mind that you need to rebind your gridview with the updated Data Source so that the changes will be reflected.In both cases, the controls are added to the controls collection for the cell.You can see that in the case of a Template Field, the exact spacing within the control becomes significant, so it’s generally better to get a reference to the control by ID using Find Control than to use the Controls collection.I tried manually writing the Sub as you sugested and got the following error: BC30506: Handles clause requires a With Events variable defined in the containing type or one of its base types. So I removed the Handles clause and manually set On Row Editing="... :) I thought there was going to have to be some complicated trickery to get this working. This will automatically generate the method that that handles the edit event for the Grid View.
