ASPxClientGridViewBatchEditStartEditingEventArgs.rowValues Property

Gets a hashtable that maintains information about editable cells.

Declaration

rowValues: any

Property Value

Type Description
any

A hashtable that stores information about editable cells.

Remarks

The rowValues structure is a hashtable that maintains information about editable cells in the following manner:

rowValues = {
   "0": {
      value: "someValue",
      text: "someDisplayText"
   }
}
//Here, "0" is an example of the column index specifying the corresponding row cell

You can manipulate entries of this hashtable to initialize/modify editor values or prevent displaying editors for particular cells by removing the corresponding entries from the rowValues structure.

Examples

This example demonstrates how to cancel editing or disable the editor conditionally for the grid when batch editing is in use. It is possible to execute your logic either on the client or server side for a complex business model.

Then, handle the grid's client-side ASPxClientGridView.BatchEditStartEditing event to either cancel the edit operation using the e.cancel property:

if (condition) e.cancel = true;

or disable the editor by obtaining its client instance:

var editor = s.GetEditor(e.focusedColumn.fieldName);
editor.SetEnabled(condition);

The custom server-side logic can be executed in the CustomJSProperties event handler:

protected void ASPxGridView1_CustomJSProperties(object sender, DevExpress.Web.ASPxGridView.ASPxGridViewClientJSPropertiesEventArgs e) {
    var clientData = new Dictionary<int, object>();
    var grid = sender as ASPxGridView;
    for (int i = 0; i < grid.VisibleRowCount; i++) {
        var rowValues = grid.GetRowValues(i, new string[] { "ID", "ServerSideExample" }) as object[];

        var key = Convert.ToInt32(rowValues[0]);
        if (key % 2 != 0)
            clientData.Add(key, "ServerSideExample");
    }
    e.Properties["cp_cellsToDisable"] = clientData;
}
