[英]How to tooltip the headers of the GridView using the list of items in ListBox
I have a GridView
and a list of items in a ListBox
. 我有一个
GridView
和ListBox
中的项目ListBox
。 Excluding the first column in the GridView
. 不包括
GridView
的第一列。
I want to tooltip each and every header with the corresponding item in the ListBox
. 我想用
ListBox
的相应项目对每个标题进行工具提示。 I mean the tooltip for GridView2.Columns[i].HeaderText = ListBox.Items[i].Tostring()
. 我的意思是
GridView2.Columns[i].HeaderText = ListBox.Items[i].Tostring()
的工具提示。
Here is what I have tried: 这是我尝试过的:
protected void GridView2_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.Header)
{
for (int i = 1; i < GridView2.Columns.Count; i++)
{
String header = GridView2.Columns[i].HeaderText;
if (header.Length != 0)
{
e.Row.Cells[i].ToolTip = ListBox4.Items[i].ToString().Trim();
}
}
}
}
This is giving me an exception error: Index was out of range. 这给了我一个异常错误:索引超出范围。 Must be non-negative and less than the size of the collection.
必须为非负数并且小于集合的大小。
Kindly help. 请帮助。 Thank you.
谢谢。
protected void GridView2_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.Header)
{
for (int i = 1; i < GridView2.Columns.Count; i++)
{
String header = GridView2.Columns[i].HeaderText;
if (header.Length != 0)
{
e.Row.Cells[i+1].ToolTip = ListBox4.Items[i].ToString().Trim();
}
}
}
}
Just suppose to use Cells[i+1] instead of Cells[i] 只是假设使用Cells [i + 1]而不是Cells [i]
