I'm getting the following error below. Can anyone suggest where I should begin looking for the error that is eliciting this message or is this indigenous to the Infragistics UltraWebGrid? And if indigenous to the UWG, is there a fix available?
TIA!Justin

You might have to post some code. But... off the top of my head - check how you are referencing your rows and columns. I think they are both zero based. For example, if you have a 5 column grid and reference the fifth column with index 5, you would get this error. The 5th column is index 4.
I've also made this mistake when looping through the columns by using ...columns.count as the upper end of my For Next. ...columns.count -1 works though.
Good luck.
Hey, thanks for the reply.
It doesn't appear to be a result of any loops, since we are using "for each" statements instead of "for" loops, so we never have to loop based on explicit indices.
The problem appears to have something to do with trying to reference the second band (i.e. UltraWebGrid.Bands(1) )
The bands were initially created through the Infragistics Quick Design UI. Referencing UltraWebGrid.Bands(0) doesn't seem to be a problem, but referencing UltraWebGrid.Bands(1) seems to elicit the indexing error, as though the second band doesn't exist. Correct me if I'm wrong, but I think I'm deducing that additional bands (other than UltraWebGrid.Bands(0) ) need to be created programmatically in order to avoid this problem...??
I can't say for sure, but I've always created bands with the codebehind. I've never had an index problem referencing the second band with an index of 1. You must be onto something.
