I put this code together around 2005 or so to add row and column highlighting to a Gridview control for ASP.NET 2.0.
This code is inspired by Ryan Scherf’s Table Row and Column Highlighting. It’s a slick solution to helping users read tabular data. I thought it would be nice to add that functionality to ASP.NET. So I created a single function that would add Ryan’s column and row highlighting code to our GridView control.
On Ryan’s demo site, you can find the crosshair javascript file (aka CSS/JavaScript Table Hilighting). You will also need a crosshair CSS file.
Place this file either in your App_Theme folder (if you are using themes), embed it in the head of the document or link to it externally.
After loading your GridView, make a call to the AddCrossHairToGridView function. It takes 5 parameters.
-
gv - The ID of the GridView Control you wish to add highlighting to.
-
top - How many rows from the top should not have highlighting.
-
right - How many rows from the right should not have highlighting.
-
bottom - How many rows from the bottom should not have highlighting.
-
left - How many rows from the left should not have highlighting.
I dropped the Javascript file inside the same folder in this example. Update the path in the RegisterClientScriptInclude line to point to whatever location you use.
