View 2 RepliesI am working with a gridview that pulls data from a SQL database based on selections in dropdown lists. The source table has six columns for attributes of the selection, but depending on what is chosen, there could be anywhere from one to six of those that are empty (all null values). When the column is empty, I would like to have it hidden so the page is less clunky and confusing.
I've searched around for an answer for the past couple days, but what I have found so far is either related to hiding columns that you know are empty which I will not know or removing them in the SQL code which I think doesn't work if the column is called for in the gridview code and doesn't exist in the query.
I have a loop where i create some string value based on certain conditions. I did place StringBuilder object outside of the loop and each time i have new row in loop i need to clear StringBuilder appended values for this row.
How do i clear those?

View 3 RepliesIf the gridview binds to empty dataset, I need to still show a gridview so that users can ADD more using the textfields in the bottom of the footer template.

I am using a Gridview with datasource is a List. How can I show the header if the List is null or for a empty gridview?
View 4 RepliesThe datasource of the datagrid is a LINQDataSource which relies on the value of a dropdownlist. In addition, I want to use the footer to insert new records - so I'd prefer not to use the empty dataset template. I am trying to find a way to always display the footer regardless if the datasource is empty or not.
EDIT:
Is there a way to create an empty/invisible object of the type in the LinqDataSource?

My program running good. But i try to add up-down icon on my gridView header. but if i make it, My break point should drop below "if comparison" For example; field.SortExpression=Category but every time CustomersGridView.SortExpression is empty when gridview.SortExp is not empty.
foreach (DataControlField field in CustomersGridView.Columns)
{
if (field.SortExpression == CustomersGridView.SortExpression)
{
return CustomersGridView.Columns.IndexOf(field);
}
}
i need :
foreach (DataControlField field in CustomersGridView.Columns)
{
if (field.SortExpression == "Category")
{
return 2;
}
}
CustomersGridView.SortExpression must not be empty!!!!!
