问题 I previously asked how to display data from a IEnumerable < IEnumberable>> collection: Changing background color of cells in DataGrid WPF All the original code is there. I believe I have an answer for the original question but now have a question based on that.* Rather than bind to one property 'Make', I'd rather bind my cells to the containing object "Column" but still display Make as the data in the grid.

At page load I want to bind the dataview to an object datagrid : dataGrid.DataSource = dv; dataGrid.DataBind(); However the time response is very high (a couple of minutes).

问题 I am using a macro to loop through files based on names and extract data which works fine for the majority of the cases, however from time to time I experience ERROR: BY variables are not properly sorted on data set CQ.CQM_20141113. where CQM_20141113 is the file I am extracting data from. In fact my macro loops through CQ.CQM_2014: and it works up until 20141113. Because of this single failure the file is then not created. I am using a data step view to "initialize" the data and then in a

问题 I have a DataView, which has been sorted in some order. How can I retrieve the values using an index. Something like this: if(dv.rows[0]["name"]=="xxx") { --- do something --- } else --- something else --- 回答1: Try the following code Move the sorted DataView to DataTable like DataTable dt = dv.ToTable(); Then use if (dt.Rows[0]["name"] == "xxx") { [...] } It will work. 回答2: Did you try: DataRowView rowView = dv[index]; 回答3: Rather than converting the whole thing back to a Table, you can work

问题 I'm trying to display records within my GridView and a few of the cells contain text with carriage returns. However when this text is displayed the carriage returns are gone. Is there an easy way to display carriage returns in a GridView Cell? I've tried using a TextBox within the cell which works but I then have the scollbars of the TextBox. I'm not too keen on this way either as the textbox may render differently in different browser. My code is displayed below, I've left my testing in

问题 I try to use the DataView RowFilter for a column with DataType "TimeSpan" as following: dv.RowFilter = ("Convert([time],System.String) LIKE '17:12:00'") I've found that the search Parameter "%17% or %12% , for the double Zeros i have to use a single one: %0%, works fine, now im not sure about the Convert(timespan, System.String) Format... .
