Updating a gridview
Let’s take a look at the implementation below: “Just a heads up: readers should know that Container.Data Item Index returns the index position in the entire dataset, which is not what you want if you are using paging and you have not used a sproc that pulls only one page of value at a time. Display Index to get the row position on the page being displayed / updated. First column containing the Check Box, second column containing a Label and Text Box for display and edit Contact Name of the Customer respectively and the third column containing a Label and Drop Down List for display and edit Country of the Customer respectively Here I am looping through the Grid View Rows and checking whether the Check Box is checked for that Row.Here I am looping through the Grid View Rows and checking whether the Check Box is checked for that Row.
After you have run the website, you will see the Grid View showing details of employees in tabular format.
You should inform the Grid View that the collection has changed. The property (Is Visible) is being set in the Model.
You may do this like so: The property is changed on a command on the viewmodel of the object, I now tried to manually fire notifypropertychange on the collectionproperty (checked that it actually did fire), but the grid still doesn't refresh. The initial load of the screen appears to work but when Is Visible is changed from false to true, the row does not reappear in the gridview.
This will improve performance in cases where you display a large number of rows to the user and the user only updates few rows.
