GridView column issues.

[reder]

Firstly, any help here would be great. Its been a while since I worked with gridviews.

I am developing in VS2005, .NET 2.0, SQL Server 2005.

I have a gridview on a page and I am binding (autogenerate columns = true) a datatable to it. Unfortunately, I have no choice but to have the autogeneration = true because the columns in the gridview will be different for different classes of users. Anyway, I have 2 columns which specify the path of an image .../folder1/image.jpg and I wish to convert these to columns displaying the image as opposed to a path. Any ideas on how to go about this. Should I add a new image columns and mirror the values from the other column.

Also, I need to implement sorting for all columns in the gridview. How can I specify a sortexpression for each column? The gridview will have 0 columns.

Your jumping around to a few different problems, you may get more responses if you limit it to one question at a time or at least detail each problem better.

There was another recent thread on here about displaying an image in a dataset if you want to do a bit of searching.

What do you mean by sorting, simply ordering columns; this can be done through datagridview properties?

Also what do you mean the gridview will have zero columns, there will be nothing to display?

Use the GridView.RowDataBound Event to change the cell text from url to an image tag:

e.Row.Cells(1).Text = String.Format("<img src=""{0}"" alt=""some text"" />", e.Row.Cells(1).Text)
