Get datakey value gridview rowupdating
The above piece of code will also do the same as label in Item Template and Textbox in the Edit Item Template.By default all the boundfields will be trasferred as Textboxes in Edit Mode.
Select Both Category and Customer tables Give Model Namespace and click on Finish. NET Gridview Footer row for inserting record, inbuilt way to edit and delete records.Then again we have to call that Bind Grid Data () method to bind data for the textboxes. You can leave a response, or trackback from your own site.So once after done with editing data, if we click update the following method will be triggered. Once we access the required fields in the code behind, we need to update the data in the database and show the updated data to the user. If the user clicks the Delete button On Row Deleting event will be fired. Going into that code we are trying to get the primary key of the employee table(Employee ID) by using Grid View Data Key Names and then This entry was posted on March 27, 2009 at am and is filed under ASP. If we use proper command names for the buttons like “EDIT”, “DELETE”, “UPDATE”, “CANCEL” these will also trigger the appropriate Grid View Events.Ok let’s move on to Code behind what we have to do when user clicks Edit, Delete, Update and Cancel When we click on Edit the On Row Editing event will be fired.After working with Data Grids so efficiently, I was scared that Grid Views were going to be a million times more complex.
I suppose my eyes got big when I saw all the new properties and methods, and wanted to try them all out. Most articles I found were for hardcoded datasources (especially on MSDN, ugh) and didn’t really help me much, so this post will be referring to Grid Views with dynamically bound datasources.
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.
In case of the bound field’s we need to check what column it is and need to use index of that cloumn, which is little hard and even in future if we change the column order If you see the Last Template Field part in the above code, I am using the link buttons for edit, update, delete and cancel.
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.
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.
We will use Template Field, whenever we want to define some custom control in the data bound controls like Grid View, Data Grid or Data Repeater.
