Getting new value gridview rowupdating event


14-Oct-2019 19:11

Unless they are Key fields, there isn't really a way to get to these. Data Bind in Row Updating (or at least before the Update is actualy processed) is better not done.

Hi there, I have the same problem and I checked the e.

New Values("brief_Descrip")) = "" Then update Description = "" Else update Description = e. To String() End If Dim update Key As Integer = row. Text If update Description = "" Or update Description = "Null" Then update Description = "Null" End If I am guessing you are Data Binding in code-behind. (Or possibly one that implements IData Source.) If so, examine the Row (use Find Control if possible) to get the Controls holding the edited values from the Cells. However, you can also examine the Cells of the Row. Cells(6), Data Control Field Cell) Dim field1Field As Bound Field = Direct Cast(field1Cell. If you use Template Fields, you should go for the Extract Values method, and extract the values from each Cell. This can be beneficial to other community members reading the thread.

When all you've got is a Hammer, Every Problem looks like a Nail. To use Find Control you would have to build a Template Field. Text = "Database was not updated for record " & row. Text ", string text " update String "." End If Catch ex As Exception Throw ex End Try Dim field1Cell As Data Control Field Cell = Direct Cast(row. You will then get a Dictionary with all values, with the field names as keys. In the Row Updating handler, you will need to extract the values like I do in my Updating handler. Template Fields are not Bound Fields, and they don't have Data Field on them. Please remember to click “Mark as Answer” on the post that helps you.

For the same reason, I don't do an actual update, and the new data doesn't show up in the Grid View.

When all you've got is a Hammer, Every Problem looks like a Nail. I have done this, it only shows the correct properties for things like Sort Expression, and the other one I mentioned. (Data Bind in Page_Load without checking Is Post Back is at the top.) And you're welcome. When all you've got is a Hammer, Every Problem looks like a Nail. I wanted to update this thread with more accurate information regarding the solution that solved the problem. Public Shared Function Find Control Recursive(By Val container As Control, By Val name As String) As Control If (container. Controls Dim found Ctrl As Control = Find Control Recursive(ctrl, name) If found Ctrl Is Not Nothing Then Return found Ctrl End If Next Return Nothing End Function I hope this helps someone else. Because this Gridview is inside of a Content Placeholder ofa Master page which in itself is inside of another Content Placeholder of another Master page I had to use the following lines of code to get the above code to locate the Gridview....

Please remember to click “Mark as Answer” on the post that helps you. Source Error: The Data Source assignment is just for the sake of the demo. The Data Control Field for the Cell knows the structure of its Cells, and will use that knowledge when you call Extract Values From Cells. So if you extract values from the 7th column, you should be fine.

Only for Bound Fields in Read Only mode is the value in the Text property of the Cell itself.

(It's in the Labels below the Grid View just to show the data was received properly.) The important thing is to extract the values from the Cells in a way that fits the structure of each Cell.

Checked = True Then Dim sql As String = "SELECT * FROM " tbl Name " WHERE display Record = 'True' ORDER BY data_text;" da = New Sql Data Adapter(sql, str Connection) Else Dim sql As String = "SELECT * FROM " tbl Name " WHERE needs Translation = 'True' and display Record = 'True' ORDER BY data_text;" da = New Sql Data Adapter(sql, str Connection) End If Else If Check Box1. Hi, For accessing Text Box in Template Field, try this: Text Box tb = (Text Box)Grid View4. If the value is there at that time, step through your code one step at a time, and see when it changes.

This can be beneficial to other community members reading the thread. Whenever I do things like this, the data is where I expect it. New Values or the Controls in the Row.) Good to hear you got it working. I would have loved adding another item to my list of things. This can be beneficial to other community members reading the thread. Equals(name)) Then Return container End If For Each ctrl As Control In container. This has dictionaries for key-, old- and new-values.
