Best Regards,__________________________________________________Sincerely, Rex Lin Microsoft Onlin... Details View updating -- New Values empty in Item Updating, Item Updated not called Hi, I'm having trouble updating data using Details View. I dont know how to wrie an event_handler ,specifically, for... How does Visual Studio create equivalents of the datagrid's and gridview's columns and rows?

Since I use a different set of templates for editing and viewing, when it switches to edit mode, I bind the datasource like this: case Details View Mode. Getting New Values and Old Values from Details View Hello, I have created a Details View in the codebehind of a web form: 1 Dim Main View As New Details View 2 3 arr Data Key Names(0) = "Unique_ID" 4 5 With Main View 6 . I am assuming they make a Data Row for each of the rows. Is the table created by gridview basically a dataset from ADO.net? Thanks to everyone that has ever helped me with any posts.

Data Source = new object[] ; It shows up fine in the view. Data presentation control in another Data presentation control Hello, I want to make a menu with datalist or gridview control. Form View Control I'm running into a behavior which seems odd to me.

Hi newbie2C#, The row in datagrid is called Data Grid Item and in gridview is called Grid View Row. Data Row is only one kind of row in Grid View control.

I created the Details View Data Binging sub which populates the field using a datatable 4. Everything works with any issues, just no data is ever returned. Mode Changing '# When the form mode changes we handle how the form loads and what it looks like here Select Case e. Edit) 'Bind Details View() 'Put into insert mode Case Details View Mode. Read Only) Bind Details View() End Select End Sub Protected Sub Details View1_Item Updating(By Val sender As Object, By Val e As System. But I could not delete or update any data as it would tell me there were no fields upon the post back in the Item Deleting or Item Updating event handlers.

Non of my fields are Template fields and they are all databound. Details View Mode Event Args ) Handles Details View1. I had created all of the databindings and everything was working very well. All I want to do is intercept the New Values and put them in my custom data solution.

-Timothy UPDATE: Ok I dont know why this is, but maybe someone can explain it to me. When I try editing any of the first 8 elements, I'm fine. So, a simple object with just an ID and a Description would give a Count of 2. I tried doing this via the Details View_Item Updating event as: e. Ironically enough..there are 8 fields in the Details View that are "editable" with the ptype being a dropdown in there--the 4th control in the edit view. So regardless as to whether I picked (1, "ptype", 20) or (3, "ptype", 20) or any other number in the first parameter below 8 -- it worked fine.I did debug and put a line: dim x as integer = e.newvalues.count and it was recording 7 (or 8--i forget). I haven't seen the rest of your page so I can only guess, but my take is you're not supplying a value for ptype in the code before (e.g. Command Argument, "Title", "New Value") You'll see it crashes with an error stating that Title (or whatever column name you have) already exists. File Name Catch ex As Exception File Upload Report. Message End Try End If End Sub Thanks, Rob Not sure if it helps in resolving the error, but look at this: dim x as integer = e.newvalues.count The Count property of the New Values collection has nothing to do with the number of records that the Details View is displaying. Count refers to the number of fields / columns that your object has. NET 2.0 Instant Results and Beginning Dreamweaver MX / MX 2004Ok....ultimately, what I am tryign to do is take the current item being edited and put the value of a selected dropdown into the value "ptype" for the currently selected record in the detailsview. What's odd--is this works for the first 8 records--this line. Details View Update Event Ar gs) _ Handles Details View1. New Values("Title") = "New Title Here" End Sub This sets or overwrites the value of the parameter called Title. Imar --------------------------------------- Imar Spaanjaars I used the same design as Imar did on the 3-layer article and so I was able to see what values were passed into my "paintings" object and each one was passed correctly. Selected Value) I thought that this would put the value into Ptype for the currently selected item. So, I thought that if there were 12 records in my detailsview, there would be 12 "newvalues"..so, I thought e. Intelli Sense for New Values might have revealed that: "Gets a dictionary that contains the new field name/value pairs for the record to update" Imar --------------------------------------- Imar Spaanjaars Cheers, Imar --------------------------------------- Imar Spaanjaars I actually debugged and even though I had e.newvalues(e.commandargument, "ptype", dropdownlist1.selectedvalue) which translated to (1, "ptype", 20) where 20 is and id to a table value and 1 is the second field (0-based array) of the record which is not ptype---it still passed the right parameters into my object.
