Reconfigure the "Enter" key functions on EditMode

Zahid, not sure if this will help, but you can try to reduce the timeout length that invokes the method, from 500 to 50. See if that reduces or eliminates the flickering issue.

Hi James,

Thanks for your post. I have column freezing enabled.

When i have one or more columns frozen then there is no flickering and everything works fine. Otherwise not

Did you mean that, there should be no flicker even if we dont have any column frozen and just freezing is enabled?

Thanks

Zahid

When i have columns outside the viewable area and the horizontal scrollbar is enabled. Then when i select the next row, the horizontal scroll bar flickers. that is, it goes to position 0 (zero) and comes back to appropriate position to focus the highlighted cell. I want to keep the scroll bar fixed.

Any idea of this?

Thanks

Zahid

Zahid, do you have column freezing enabled? The row selection and cell selection should be running synchronously so the horizontal scrolling/flickering shouldn't be noticed.

Hi Zahid,

I am really sorry but its the default behaviour of WebGrid if we select a row the focus will be on first cell.

If you want you can use AutoFit columns in the WebGrid it will make all the column fit in the WeBgrid without horizontal scrollbar.

I need the behaviour of MS Excel while editing the grid cells. After users modified a cell content followed by pressing Enter key the next cell at the next row (rowIndex+1) at the same column will be directly highlighted.

I got a solution from

http://support.intersoftpt.com/docs/webgrid/5.0.7200/Reconfigure%20the%20Enter%20key%20functions%20on%20EditMode.html

It is as follows

function WebGrid1_OnEditKeyDown(controlId)
{
   if(event.keyCode == 13) {
    //cancel the event as it'll be handled manually
    event.returnValue = false;
   
    var grid = ISGetObject("WebGrid1");
   
    //get currently active edit cell
    var ac = grid.GetActiveEditCell();
   
    if(ac.rowElement.type == "Record") {
     //get the table object
     var tbl = grid.Tables[ac.tblName];
     grid.ExitEdit(1,0,0) // exit and update the row if dirty

     //find out if the table of current row is parent
     var isParent = (tbl.GetChildTables().length > 0)?true : false;
    
     window.setTimeout(function() {SelectNext(ac, isParent);},500);
    
     //you can try to remove this line if you receive a javascript error
     return false;
    }
   }
   return true;
  }
 
  function SelectNext(ac, isParent) {
   var curRow = ac.rowElement;
   var tblElm = wgGetTable(curRow);
   var curRowIndex = curRow.rowIndex;
  
   //if a table is a parent, the index numbering increases by 2
   var i = (isParent)? 2 : 1;
  
   //check if current row is the last row of the table
   if(curRowIndex < tblElm.rows.length-i){
    //get destination now
    var destRow = wgGetRowByPosition(tblElm, curRowIndex+i);
   
    //highlight the destination row
    //wgHighlightROw(destRow);
   
    //get the column name
    var cellName = wgGetColNameByCell(ac.element);
   
    //get the destination cell
    var destCell = wgGetCellByName(destRow, cellName);
  
    //select nextRow and highlight the destination cell
    window.setTimeout(function() { MoveRow(destRow,destCell);}, 500);
   
   }
  }
 
  function MoveRow(destRow, destCell)
  {
   wgGetRowByElement(destRow).Select();
   wgHighlightEditCell(destCell);
  }

The proble with this is in wgGetRowByElement(destRow).Select()

When i have columns outside the viewable area and the horizontal scrollbar is enabled. Then when i select the next row, the horizontal scroll bar flickers. that is, it goes to position 0 (zero) and comes back to appropriate position to focus the highlighted cell. I want to keep the scroll bar fixed.

Any idea of this?

Thanks
