This is the if around this.... and the replacement code (for me line 146-207)
The key to the problem is the repeatcolumns when= 0 there was no checking for this... so i made a simple bool
bool haveItems = (dataList.RepeatColumns > 0) ?
true : false;
and everywhere that used repeaatcolkms, i but an haveItems && so that the boolean check is first.
if
(dataList.ItemTemplate != null)
{
writer.WriteLine();
writer.WriteBeginTag(
"tbody");
writer.Write(
HtmlTextWriter.TagRightChar);
writer.Indent++;
int nItemsInColumn = (int)Math.Ceiling(((Double)dataList.Items.Count)
/ ((Double)dataList.RepeatColumns));
bool haveItems = (dataList.RepeatColumns > 0) ?
true : false;
for (int iItem = 0; iItem < dataList.Items.Count; iItem++)
{
int nRow = (haveItems) ? (iItem / dataList.RepeatColumns) : 0;
int nCol = (haveItems) ? (iItem % dataList.RepeatColumns) : 0;
int nDesiredIndex = iItem;
if (dataList.RepeatDirection ==
RepeatDirection.Vertical)
{
nDesiredIndex = (nCol * nItemsInColumn) + nRow;
}
if (haveItems && (iItem % dataList.RepeatColumns) == 0)
{
writer.WriteLine();
writer.WriteBeginTag(
"tr");
writer.Write(
HtmlTextWriter.TagRightChar);
writer.Indent++;
}
writer.WriteLine();
writer.WriteBeginTag(
"td");
writer.Write(
HtmlTextWriter.TagRightChar);
writer.Indent++;
foreach (Control itemCtrl
in dataList.Items[iItem].Controls)
{
itemCtrl.RenderControl(writer);
}
writer.Indent--;
writer.WriteLine();
writer.WriteEndTag(
"td");
if (haveItems && ((iItem + 1) % dataList.RepeatColumns) == 0)
{
writer.Indent--;
writer.WriteLine();
writer.WriteEndTag(
"tr");
}
}
if (haveItems && (dataList.Items.Count % dataList.RepeatColumns) != 0)
{
writer.Indent--;
writer.WriteLine();
writer.WriteEndTag(
"tr");
}
writer.Indent--;
writer.WriteLine();
writer.WriteEndTag(
"tbody");
}
