Gridview rowupdating event in c online dating hoger opgeleiden
I am sharing this because I see a lot of questions on the forums on how to get the value from the Grid View object, and I know how.
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.
If you are new to using a grid control, I would recommend you to read my blogs “Using Grid View in ASP. The Eval method takes the name of a data field and returns a string containing the value of that field from the current record in the data source.
In the template field I will Place a label or some controls, So that it’s very easy to access those controls in the code behind by using Find Control method. Item Template is the content to display for the items in the Template Field.
To avoid this we need to keep the property Read Only as false, Then in the edit mode nothing will happenes. The reason I use Template Field instead of Bound Field is that, it is very easy to grab those controls in the codebehind if we user labels or textboxes.
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.
Here in Grid View, in the beginning the major part is to make the decision of putting either a bound field or a template field and the answer is simple: When we want to place any control inside the Grid View then we can go for template field, otherwise bound field will be simpler.
I hope the above information was a little bit helpful for you, kindly let me know your valuable feedback or thoughts.
Suppose if we are trying to hide primary key of our table, there is actually no need to hide. In the above Snippet you are seeing a label in Item Template that means whenever we are showing Grid View to the user Label will be visible to the user.
