How to check the rad gridview selected item is file or folder in RAD File explorer

[sandhya]

Hi

This is my requirement

I want to disable the DownloadFile option  if i click on folder and once i select the folder if no records are there in grid that time also it should disable downloadFile option.
If click on file DownloadFile option shuld be enable
All these things happen rad gridview context menu shown and file or folder click.
Note:DownloadFile i added custom button.

i have done like this for if no records are there to display in gridview.But in case of if click on folder i want to disable download option and if i click on file download file option shuld be enable.

 

 

function OnClientShown(oMenu, args) {

 

 

 

var iCount =0;

 

 

 

var deleteMenuItem = oMenu.findItemByValue("Delete");

 

 

 

var radExplorer = $find("<%# radFileExplorer.ClientID %>");

 

 

 

var getGrid = radExplorer.get_grid();

 

 

 

var table = getGrid.get_masterTableView();

 

 

 

var rows = table.get_dataItems();

 

 

 

var downloadFileItem = oMenu.findItemByValue("Download_File");

 

 

 

if (rows.length == 0) {

 

downloadFileItem.set_enabled(

 

false);

 

} 

 

 

 

deleteMenuItem.set_enabled(

 

true);

 

}

Please can u solve this prob.

Thanks

Hi Sandhya,

You can use RadFileExplorer's get_selectedItem() client-side method to get reference to the currently selected FileExplorerItem, then you can check if this item is file or folder using its isDirectory() method, e.g.:

var radExplorer = $find("<%# radFileExplorer.ClientID %>");
var selectedItem = radExplorer.get_selectedItem();
if(selectedItem.isDirectory())
    alert("Selected Item is a Folder");
elese
    alert("Selected Item is a File");

I hope this helps.

Kind regards,

Hi Rohan,

I am not quite sure I understand the exact question. Could you please describe in more detail when exactly do you need to check if a folder is empty?

You can check if the currently loaded folder is empty by examining the number of items of the fileList, e.g.:

if(explorer.get_fileList().get_items().length == 0)
    alert("Folder is empty");
