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.
Then add any extended data-type, like a time value, xml etc - and the update throws the exceptions @digital-void, please check the minimal testcase in my commit above. Update(Data Row data Rows, Data Table Mapping table Mapping) at System.
If you need help compiling/running with NUnit let me know.
One comment: you have set Use Preload to true in your connection string. Use Extended Types = false; the exception changes to: System.
Main() in d:\Projects\Postgres Csharp\Postgres Csharp Tests\Postgres Csharp Tests\Program.cs:line 23 at System. For example, if the user has a column of type json, the CLR type for that is String, and the first best backend type for this is text. As 2.x is quite old by now, I really suggest you update to the latest 3.0.x - I'm definitely not going to have any time to fix this kind of bug in 2.x. (B) Tweak Npgsql according to pr #577, and also insert tricks at Row Updating.
I think though using another Conflict Option work. One thing we do wrong is here: https://github.com/npgsql/npgsql/blob/master/Npgsql/Npgsql Command Builder.cs#L389 It should use a Npgsql Type Info that uses the exact same data type on the postgresql backend, and not the first best CLR type. I'm not sure what exactly changed from 2 to 3's parameter handling but the issue seems gone... I have 2 possible workarounds, and I want to know whether it is useful or not. Set All Values = true, if using Npgsql Data Adapter/Npgsql Command Builder.
You can see the C# code below will give the row number whatever you are editing by New Edit Index property.
So Grid View will put the appropriate row into the Edit Mode by assigning row number to its Edit Index property. You can follow any responses to this entry through the RSS 2.0 feed.
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.
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.
