Forms Data Controls :: Save Batch Of Changes From DataGrid Or GridView

Jan 29, 2010

I have a set of data that has been displayed as just a simple GridView with the item name being a hyperlink to view details. I'm attempting to update this scenario so certain fields (sortOrder and isApproved) are editable from the main page and do not require visiting each item in the grid. I have converted the GridView to a DataGrid and have included a TemplateColumn for the columns in question. I have them hooked up to display the values appropriately. At this point, I'm trying to find a way to peek into the DataGrid and it's related data source to determine if the values have changed on the click event of a button. At that point, I could persist those changes back to the respective SharePoint list.

I'm not very familiar with the DataGrid, or GridView for that matter. Can anyone point me in the correct direction on how I could gain access to the data source at an item/row level during a button click event where the button exists outside the context of the DataGrid?

Forms Data Controls :: Failed To Load Viewstate When Gridview Control - Replace Gridview With Datagrid

Apr 5, 2010

Failed to load viewstate. The control tree into which viewstate is being loaded must match the control tree that was used to save viewstate during the previous request. For example, when adding controls dynamically, the controls added during a post-back must match the type and position of the controls added during the initial request.

The above error occurs with gridview control , when used with template field columns with item template / and edit templates etc.
updating a row within gridview, at the time of loadiong it loads perfectly fined, but when tried to modify an existing row within gridview control, then it produces the error. Make sure the grid view control has to be a child control which manages the child table info with in a master form. to reproduce the above problem the grid view must be loading the child records info of a master within the masterform, meaning both master data and gridview data all to be managed in one single form.

I had to replace gridview control with datagrid and then it worked perfectly fine. I wasted almost 4 days of my time., there is no way we could figure out the problem. here is the full info of the problem.

Forms Data Controls :: On Fly Programatic Datagrid / Gridview In VB

May 12, 2010

I have a interesting problem and being relatively new to .NET I thought to try the forum for some guidance. I need to present information from a database, typical, but I need to create stand alone views of the data based on the "category" for the reported information. I don't know how many or how few categories I might need to generate but each needs to be displayed in its own datagrid or gridview. I did a prototype report where I could dynamically generate a variable number of columns in a generic datagrid already placed on the page based on the database but the user "changed their minds", also typical, and want a different view (actually views). Does anyone have any thoughts on creating anywhere from 1 to a dozen (or more) datagrids in the code behind and then pushing them out to the aspx page for the user? Can you dynamically generate datagrids and gridviews on the fly? Or would you need to?

Forms Data Controls :: Gridview Will No Longer Show The Data - Datagrid Datasource = Null

Feb 25, 2011

I am familiar with populating a gridview with data. I am able to bind the Data pulled from the database into the gridview

gridview.DataSource = myDataTable;
gridview.Databound.

If I write the following code, teh gridview will no longer show the data

gridview.DataSource = null;
gridview.Databound.

My question is , I want to make the same thing with a user control that contain a gridview. when I use the user control in an aspx page, I am able to populate it with data, but when I try to make this code, the Datasource does not show, instead, I see .DV. So I tried this code but then , I do not see DataSource property instead I see DV (DataView), when I put .DV = null, I get an error message that the object is not in existed. any idea how to clear the user control gridview from its data.

Forms Data Controls :: Change One Section Code From DataGrid To GridView?

Aug 2, 2010

I'm trying to change one section in code from DataGrid format to GridView format. The reasoning is that the sample application that was displayed was using a DataGrid even though it should have been using a Gridview for 2.0 and above. Most of it shows up without an error except one line in 3 lines which are pretty much the same. I bolded them and just want to know how do I re-write them for the Gridview?

Protected Sub NewsGrid_RowCommand(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewCommandEventArgs) Handles NewsGrid.RowCommand
Dim connection As SqlConnection = CreateConnection()
If e.CommandName = "Delete" Then
Dim com As New SqlCommand("DELETE FROM ElectPageEditor WHERE NewsID = @NewsID", connection)
com.Parameters.AddWithValue("@NewsID", e.Item.Cells(0).Text)
Try
connection.Open()
com.ExecuteNonQuery()
Catch generatedExceptionName As SqlException
Finally

End Try
ElseIf e.CommandName = "Edit" Then
