Hi,

In my project i have used UltraWebGrid to show the list of files that are present in a folder. I want to change it to WebDataGrid. I have the following questions

1) How to add a row to WebDataGrid in server side?

Previously, i get the list of files from a location and put it in a array , then depending upon the length of the array, i add new row to the UltraGrid. Below is the code

for (int i = 0; i < remoteval.Length; i++)

{

Infragistics.WebUI.UltraWebGrid.UltraGridRow drow ;

drow = new Infragistics.WebUI.UltraWebGrid.UltraGridRow();

gridFiles.Rows.Add(drow);

drow.Cells[0].Text = imgFileLoc;

drow.Cells[1].Text = fileName;

drow.Cells[2].Text = filePath;

drow.Cells[3].Text = filesize;

gridFiles.Rows[i].Cells[0].Title = "Date Created: " + filecreated + '\n' + "Size: " + filesize;

gridFiles.Rows[i].Cells[1].Title = "Date Created: " + filecreated + '\n' + "Size: " + filesize;

}

I would like to do the same in WebDataGrid. One way of doing it is by adding the array into a DataTable and then bind the DataGrid to that datatable. This is a lengthy process and also i am not able to assign the tooltip for that row. Is there another way of doing it?

2) If there is a zip files in that folder and the user double click on the zip file, i will extract that zip and then show the Zip contents in the UltraGrid. Irrespective of the row position where the zip file is present, i will add the zip file contents to the next position starting from the zip file. The advantage of this is that user can download only the required files from the zip contents instead of downloading the zip file.

gridFiles.Rows.Insert(currentIDX + i + 1, new Infragistics.WebUI.UltraWebGrid.UltraGridRow(new object[] { "", FileName, FileLoc }));

How to achieve it using DataGrid. I have attached a zip file that contain 2 images that shows what happens before and after unzip of the files.
