Forms Data Controls :: How To Check For Empty Cells
Jan 13, 2010
i'm trying to check for an empty cell in a gridview.
On the RowDataBound event I tried the following:
- if (String.IsNullOrEmpty(e.Row.Cells[2].Text.Trim()))
- if (String.IsNullOrEmpty(e.Row.Cells[2].Text))
- if (e.Row.Cells[2].Text == "")
None of them worked.
I'm using boundfields. I can't use a TemplateField with a label because I need to check for other stuff for that column in the RowDataBound event by doing e.Row.Cells[2].Text - that only works if I use boundfields.
string s = "" when I click on the DeleteImage1 button in the EditItemTemplate row.Cells[2].Text is an empty string in gridView_RowCommand (3 buttons inside an EditItemTemplate)
I am using c# with VS 2010 and dynamic data. I have a gridview that is populated by scaffolding. I then want to use the "Delete" command on the row. While the command works fine, it does not seem to know the datarecord has child tables in a one to many relationship, thus it wont properly delete the child tables before deleting the parent table. Which is fine, i can call some linq to sql to get the table id and delete all of its children before the parent table is deleted. Odd thing is, the Gridview is retruning "" emtpry strings for the cell that has the table uniqe ID.

I have a gridview with two bound fields. On clicking a button i want to display the values in first row of gridview in two textboxes. But if gridview cell is empty i am getting the text in textbox to which the value of cell is given as -' 'i know my problem will be solved if i use the template fields instead. But i want a solution while maintaining the bound fields ,if any.
How do I check if my value is empty AND Isnull? I need to check for both, using ISNULL is not enough because the data can change just so that it is empty.
Now I know this works.. but what is the right way to have this? I don't want to be checking something twice instead of just having it written out once.
