Gridview rowupdating event from code what is dating like in the middle east
Developers prefer manual coding but an editable Grid View is a good way to update a database. Step 1Put a Grid View in your aspx page then write code for the page load to fill the Grid View.After filling the Grid View click on the Grid View; click EDIT Column convert to field to convert this field into a Template Field.I am only going to show the different ways we can use code to take the value from Grid View.First, we have to very be clear in our mind that there are mainly two ways of taking the cell value from the Grid View: This code is for taking the value apart from the Grid View events; that is, any common event using a sender object.A Grid View Edit Event Args object is passed to the event-handling method, which enables you to determine the index of the current row and to indicate that the edit operation should be canceled. before that i want just using Find control and casting and then retrieving all lot code. If values are same they could notify user to change the value(give new cell value).This function is use to fetch data from the Vendor table, fills data in a Data Table object and find it to a Grid View control using the Data Source property. For more information I am attaching my test application and database, so download it for better result and if you liked this article or you have any advice about my any article don't be hesitate drop me a comment on c-sharpcorner comment section.
As a beginner it's very tough and challenging to work with controls like a Grid View in ASP. Even I faced difficulties at the starting point of my career. Here, I am not going to explain about Grid View and other events in it, because there are a lot of good articles about that.
Every one can use it to compare the new value with old ones.
After searching long and hard I found a great article that solved my issue.
But Values retrieved from the tex Boxes are old values (not the newly typed in values in Edit mode) So in effect no updating is happening.
Tell me where I have gone wrong and Please suggest some ways to fix this problem. Here, when click Edit button on "C" row, and modified values from f1C to f1CXX; and in the rowupdating method, it is getting f1CXX only... I am getting some problems in the code you posted aslo.
