Invalid Argument

Using dynamic smart rendering, I get an "Invalid Argument" with IE8 on this code in dhtmlxgrid.js:

    this.hdr.rows[0].cells[i].style.width=this.cellWidthPX[i]+"px";

I've determined it's not from having a width attribute in my XML header columns:

    <column type="dyn">
    
If I put width="some number" in the column tag, then it works, but it sets a specific width rather than dividing the columns evenly.

This is not a problem in Firefox, just Internet Explorer.

Each <column> tag must have width atrribute. Otherwise IE will return Invalid Argumetn error. 
You can use setInitWidthsP() method to set column width in percents. Please find example here http://www.dhtmlx.com/docs/products/dhtmlxGrid/samples/10_grids_manipulations/08_pro_resize.html

The only problem is that it appears setInitWidthsP() is used when you know how many columns are going to be in the grid. I want to be able to use the same HTML for reports from multiple tables, so I won't always have the number of columns. My XML is used to set the column headers and determine the number of columns.

Firefox works as I expected it to -- it didn't encounter column widths in the XML, so it spread them out evenly across the grid. It's only Internet Explorer that threw an error.

Also, when I run this from IE without column widths, it displays the column header row just as it does in Firefox -- spread evenly across the grid width. It's only after displaying the header row that it throws the error.

Hello, 

you can try to set * as a width for each column. In this case the width will be calcilated automatically:

<?xml version="1.0"?><rows total_count='1000' pos='0'> <head><column type='dyn' width="*">Cust#</column><column type='dyn' width="*">Invoice #</column>.....<column type='dyn' width="*">Unit Price</column></head> .....
