Forms Data Controls :: Best Way To Auto-format Auto-generated Grid Columns?
Mar 9, 2010I 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.

View 4 RepliesHide Columns In GridView With Auto - Generated Columns?
Jan 19, 2010GridView1.Columns.Count is always zero even SqlDataSource1.DataBind();
But Grid is ok I can do
for (int i = 0; i < GridView1.HeaderRow.Cells.Count;i++)
I rename request headers here but
GridView1.Columns[i].Visible = false;
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, 2010I 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 :: How To Delete An Auto Generated Column From A Gridview
Feb 1, 2011I 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:-

Forms Data Controls :: Remove Multiple Gridview Columns Before Excel Export?
Mar 29, 2011I'm trying to find a code to delete multiple columns because when you delete a column the next column takes his place so for example:
If you delete column 6 then column 7 becomes column six.
I tried the following code with an for loop & a while loop:
Dim field As DataControlField = gv.Columns(i)
gv.Columns.Remove(field)
&
gv.columns.removeat(i)
But same case that the column 7 becomes column 6
The variable removeColumns is an array with the column number that need to be deleted.
If wanted I can also provide the Header Names

Forms Data Controls :: An Error Has Occurred Because A Control With Auto-generated Id?
Feb 25, 2011Currently, 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.
Type Of Data In GridView / Listview Bound - Template And Auto Generated Fields
Aug 18, 2010Background: I'm populating lots of asp.net c# GridViews and ListViews from a database and subsequently users may export them to Excel. I want export as native Excel (not html). I can't use office automation, and I'm using JET which works fine. I have no control over users' machines. Question: When doing the export, you have to tell Jet what type each field is, in my case "text" (varchar) or "numeric" (double). The difference is that if you export a numeric column, the users can sum the data in Excel, where as strings are exported with a leading apostrophe and so are not much use in arithmetic.
Currently I parse the first data row of the Grid/ListView, check if each value is numeric or text, and assign a type to the column accordingly. That works, except for when I have something in the first column which looks numeric but in fact is a text string. I don't want to parse every row in order to be sure I have the correct data type as some of these exports are quite large. When I load the Grid/ListView from the database, the database certainly knows what type each field is. So my question is... how do I extract the type of the database item behind a a Grid/ListView item? I could explicitly code it as an attribute on the item, but that's duplicating information I already have, if only I can get to it. I know that where I have a DataTable then I can get the underlying type from that, but mostly I don't have tables handy, just the Grid/ListView. Note that Jet will throw if you try to insert an empty string into a nullable numeric column. The way to do this is to omit that column name from the insert statement, or output a zero.
