if you want to refresh your user control to Refresh the data of your grid view, then simply call your grid view bind function here again just after uploading new documents.
I have two problems:
I am trying to connect a form view that is inside the content section of an accordion. I choose my ObjectDataSource, configure it and drop it on the page with the designer. When I switch back to the code view there is no code at all for the ObjectDataSource connection. When I run the page the form view displays no data whatsoever. I even told the accordion that the datasource ID was Object DataSource and it errors out saying that it doesn't exist! Why is this happening?
I need to click a button and dynamically create a new accordion pane with a blank form view that can be filled out and update the database. Theoretically I need to be able to create as many new forms as needed. How can I accomplish this?
I want to create a reusable user control which contains a date time picker in asp.net. Need to add this user control in a grid view as column.While clicking the column,date time picker has to be displayed.Which is the suitable method,Creating the component or creating the user control.Also want to know,How to add this component in to the toolbox?
The main difference between a component and a control is that a component has no UI... so clearly it is a control that you want as there must be a user interface portion for a date picker.
As for getting your control into the toolbox, right click it and there is an option to add item(s) which presents a browse dialog allowing you to locate the assembly containing your control.
You can drag and drop UserControls without them being in the tool box. When you're in design mode for an .aspx or .ascx page, you can drag and drop the UserControl from the Solution Explorer (by just selecting the file and dragging it).
