Forms Data Controls :: Grid View - Can't Get The Value Of An Hidden Field's Footer Row

Dec 3, 2010

I can't get this to work:

I have a grid view with several TemplateFields. A couple of them are set to Visible=False; each template field has an EditItemTemplate, an ItemTemplate and a FooterTemplate.

[Code]....

While in GridView_RowUpdating event, the value bounded to the EditItemTemplate is properly read

[Code]....

so, debugging ttbImp.Text = "4"; But when trying to get the value bounded to the FooterTemplate, the label contains no values.

[Code]....

so, while debugging, lblImp.Text = "";

why that? I believe it has to do with the hidden visibility of the field, but I can't understand why it reads the value inEditItemTemplate, and it doesn't in FooterTemplate.

Forms Data Controls :: Grouping The Data Rows Of The Grid View Under The Column Selected?

Sep 22, 2010

I have a grid view that needs to be shown group wise. The grouping of the data should be dynamic and that is based on the column that is selected.

In general it should list all the rows and based on the coloumn header selected, all the rows should group by that column and should be listed under it. That also needs the template column for the check box and while group by there should be a check all option available for each group.

Even having the collapse and expand option for each groups is required.

I currently use VS 2005 and later will use 2008 and 2010, but will use the aspx code and not xaml.

Forms Data Controls :: Changing Row Color In Grid View Based On A Boolean Field Using Rowdatabound Event

Aug 4, 2010

I know that variations of this same question have been posed numerous times - but I can't quite seem to find the exact solution.

I would like any row in my gridview where the boolean field "Approved" is True to be shaded gray. Here is the code that I'm using, but every row ends up being gray, regardless of the value in that "Approved" field. My guess is that I'm not correctly evaluating the boolean value in this field (which is actually a yes/no field in MS Access), Not sure if I should be reading that value as "-1", "Yes" or "True" or "NotNull"? Anyway, here is the code:
