Dynamically Modifying Repeater Control Column?
Jan 7, 2013I have an asp:repeater control on a form. It contains 4 columns. Based on a certain value as a result of a database read, the 4th column, needs to contain a button control else it will contain plain text. How do I this in the code-behind using VB.Net? The code that I have is below but it's not working. I've never worked with a repeater control before.
Code:

View 6 RepliesForms Data Controls :: Modifying HeaderCell Style During RowDataBound?
Jun 10, 2010I have a very simple sub routine which I call from RowDataBind that adds a sort arrow image to the cell if a SortExpression exists. It works great except for the problem that if the gridview renders a wide table, the header text wraps and the image appears on a different line to the text. Therefore, I need to modify my subroutine so that if the header text is only one word in length, then a white-space:nowrap rule is placed on the header cell of that column.Sound really easy, but I just cannot get it to work. For some reason the white-space:nowrap rule is being added to EVERY header cell, regardless of the text inside it.

Forms Data Controls :: Refresh Gridview On The Same Page After Modifying Data?
Feb 15, 2011I have a gridview that has allowPaging and AllowSorting set to true. It is bound to a sqldatasource with the selectCommand firing a sql query. The sqldatasource has EnableCaching = true, and caching duration = "60". The idea is to run the paging, sorting, etc from the cache.
A separate dataUpdate event updates the data that is being loaded in the grid view, but I am not able to see the change in the gridview data till 30 seconds (caching duration) .
What is the best way to force refresh the gridview data by the dataUpdate event?
I came across this artice that tells to use CacheKeyDependency, but when I implemented it, the gridview gets refreshed at every dataUpdate event, but also the paging and sorting fires the sqldatasource Selectcommand sql query. I want this query to be fired only on dataUpdate.
