How to: Use ASPxTrackBar Client-API

  • 2 minutes to read

The code sample below demonstrates how you can use the ASPxTrackBar control to specify a filter condition for the ASPxGridView control.

Handle the ASPxClientTrackBar.PositionChanging event to update label content that displays the currently selected range. The ASPxClientTrackBar.PositionChanged event handler applies the specified filter to the grid by using the ASPxClientGridView.ApplyFilter method. Note that the ASPxTrackBar.ValueChangedDelay property specifies the time interval between when a user changes the editor’s value and when the filter is applied.

The image below shows the result.

TrackBar_Grid

function initLbRange() {
     lbRange.SetText('$' + tbSale.GetPositionStart() + ',000 - $' + tbSale.GetPositionEnd() + ',000');
     updateGrid();
};

function updateLbRange(s, e) {
     lbRange.SetText('$' + e.newPositionStart + ',000 - $' + e.newPositionEnd + ',000');
};

function updateGrid() {
     var filterCondition = "[Sale] > " + tbSale.GetPositionStart() * 1000 
     + " AND [Sale] < " + tbSale.GetPositionEnd() * 1000;
     grid.ApplyFilter(filterCondition);
};
