Forms Data Controls :: Best Way To Auto-format Auto-generated Grid Columns?

Mar 9, 2010

I have a "database explorer" page that is desgined to be pointed to an unknown database and allow users to browse the data, so it basically uses the SQL system tables to develop its queries and pull in data to tables using auto-generate columns.The problem that I have is that I would like certain types of columns to have certain formats and I'm wondering the best way to go about it. I could format the column in code in the RowDataBound event I assume, but I'm wondering if there some better standard way to do this? Is there a setting of any kind that I can use? For example I want all of the datetime fields to be formated for short date, like {0:d}, I want decimal fields to have 4 decimal places, etc.

Forms Data Controls :: How To Delete An Auto Generated Column From A Gridview

Feb 1, 2011

I am currently working on a module in which I am creating an auto generated column gridview, and I have set the Auto generate edit button field to true. What happens now when I click the edit button The primary key field is turned in to edit mode which I want to restrict from being updated.

To restrict the same I have hard coded a template field which holds that column, But as I have set the AutoGenerateColumns Property to true the gridview automatically creates a duplicate field for holding the primary key column. For which I want to delete that particular column.

My Designer Code is:-

in page load I am binding the grid view.

Hide Columns In GridView With Auto - Generated Columns?

I can't use it because of GridView1.Columns.Count is 0. So how can I hide them ?

Prevent HTML Encoding In Auto Generated GridView Columns?

Jan 30, 2010

I have a GridView bound to a DataTable that I construct. Most columns in the table contain the raw HTML for a hypelinklink, and I would like that HTML to render as a link in the browser, but the GridView is automatically encoding the HTML, so it renders as markup.

How can I avoid this without explicitly adding HyperLink, or any other, columns?

Forms Data Controls :: Hiding First 2 Columns Of A Gridview But Keep Column Location The Same?

Oct 25, 2010

using vb.net/asp.net 2005

I have a gridview with columns (pseudo-code):

<COLUMNS>
AuthorFirstname
AuthorLastName
BookTitle
YearPublished
</COLUMNS>

what I would like to do is to only show the AuthorFirstName and AuthorLastName columns for the first row of each author. I am easily doing this with:

[Code]....

However the issue that I'm seeing now is the formatting what happens is that after the first row that the Author names are hidden but then the BookTitle and YearPublished become the new cell(0) and cell(1) respectively which means that book and year are displaying underneath the author names columns. so my goal is to do 2 things:

1 have BookTitle and YearPublished render under the correct headers and

2. For the second row and after I would like the cell to appear the same as the background, I dont want the user to be seeing what looks like an empty cell or textbox there.

Forms Data Controls :: Splitting GridView Column Into Multiple Columns?

Jan 10, 2011

I have a gridview that is being populated by an oracle DB. The gridview have 2 columns now one shows years and the other is a checkbox column. What is happening is my years column is very long and I wanted to know if I could split the column in half. I want say from 1970-1990 in the first column. The second column will have the checkboxes for the first. I want the third column to have 1991-present day and the fourth column to have the checkboxes for the third column. Can the grid view do this or is this something I have to do in oracle and have the gridview just display it?

ex.

1970 chk 1991 chk
1971 chk 1992 chk
1972 chk 1993 chk
1973 chk 1994 chk

Forms Data Controls :: Manually Setting The Column Width On GridView Columns?

Mar 30, 2010

I have a GridView with bound columns, for which I am manually setting the ItemWidth and HeaderWidth to 500px, and nothing happens. Is there some trick to getting this to work?

This is a column a large amount of text in it, and it keeps sizing to the width of the header text, which is simply "note". I don't want to set Wrap to false, becuase then the colummn could be thousands of px wide in cases.

Forms Data Controls :: Combine Gridview Columns Under One Column And In Separate Rows

Nov 29, 2010

I have a couple of things that are not working with my Gridview:

1) I've managed to display 3 columns in one column (see code above) but the data is separated by commas, how can I display each data item in separate rows.

2) How can I make the data unique, as I have added the distinct command which I configured in my SQL data source

3) I need the rows to not display nulls, but at the moment it isn't displaying the row if one of the columns is null?

Forms Data Controls :: An Error Has Occurred Because A Control With Auto-generated Id?

Feb 25, 2011

Currently, I am programming a web-based application with Visual Studio.NET 2003, and having a problem with an err below :

An error has occurred because a control with auto-generated id 'dgPreventiveMaintenanceSchedule:_ctl5:_ctl3' could not be located to raise a postback event. To avoid this error, explicitly set the ID property of controls that raise postback events.

That err occurs while I am rendering my datagrid for certain data. In the other words, it occasionally happens.

I've been trying to debug one by one, but I still don't any clues for this kind of err.
