Forms Data Controls :: How To Set Height And ItemSource (Business Object As DataSource For Cell) For Every Cell

Mar 24, 2010

How to set Height and ItemSource(Business Object as DataSource for Cell) for every Cell in DataGrid/ Grid? Shown below is part of code I am currently using with Grid Control. What I am currently doing is that I am using ListBoxItem, set Item Height and ItemSource at ListBoxItem Level, Add ListBoxitem to ListBox and then Add ListBox to Grid, It leaves me with just one row and multiple columns in the Grid, which is perhaps not the best way of doing it as it doesn't allow me to take benefits from UI Virtualization of Grid.

[code]....

I am open to use any control i.e. Grid/ DataGrid provided it allows me to set Cell Height and item source at Cell level. In my requirement, Cell height depends on the Item duration and size of image, which means the height of the cells may not be same across cells in any particular row.

Web Forms :: How To Retrieve The Table Cell Height In C#

Mar 19, 2011

I had a problem for a long time but now wonder how I will solve this. Perheps it is easy.

I have a <table> with two <td>. This <table> resides inside a GridView, so I FindControl like below. Now I need to do a calculation of height that if MessageBox1 have a height that is less than 306, then I need the MessageBox2 to have the remaining height.

For example if MessageBox1 has the height of 206, then MessageBox2 need to have the height of 100.

I think my problem is how to convert the height of MessageBox1 correctly and set the remaining height to MessageBox2 ?

Forms Data Controls :: Gridview And Detailsview - To Click Two Times On The Select Button To View The Detailsview?

Nov 17, 2010

Im trying to link the gridview to detailsview and I used this page as my inspiration:

http://quickstarts.asp.net/QuickStartv20/aspnet/doc/ctrlref/data/detailsview.aspx

But Im trying to do that programmatically, not with the sqldatasource. So I wrote the method that binds data to Detailsview and I call it in the page_load. The problem is that I have to click two times on the select button to view the detailsview. The first time I click on the select button nothing happens.

Converting A DetailsView TemplateField Cell Value To Short Date String

Sep 7, 2010

I have a detailsView whose date values in a cell are currently being displayed in longDateFormat, i want to convert all date values in this DetailsView to short date.

For example, instead of 6/1/2010 12:00:00 AM, i want to display just 6/1/2010

For a Gridview, i can achieve that by the code blow

Protected Sub DetailsView4_DataBound(ByVal sender As Object, ByVal e As System.EventArgs) Handles DetailsView4.DataBound
If e.Row.RowType = DataControlRowType.DataRow Then
For i As Integer = 0 To e.Row.Cells.Count - 1
Dim cellDate As Date
If Date.TryParse(e.Row.Cells(i).Text, cellDate) Then
e.Row.Cells(i).Text = String.Format("{0:d}", cellDate)
End If
Next
End If
End Sub

How can achieve the same with a DetailsView?

Retrieve Readonly Values When Using A DetailsView Control To Update A Record?

Mar 24, 2010

I'm using a detailsview control to update a record, however in this particular case there's only one field that can be changed out of a many. The update method for my object takes all fields as parameters. When the detailsview's updating method fires, the values for the readonly fields (those rendered as a Label) are not available in the e.NewValues collection.

I'm currently grabbing a reference to the object when the detailsview is databound (in the objectdatasource selected event handler), storing it in session and manually adding entries to the e.NewValues collection when updating fires. It works but seems kind of heavy handed. So, is there a better way to get the read only values back into my update method? Or is there a better way of doing this altogether?
