Hi all,

In radgrid,how to change the icon of filter button? Please help.

Thanks in advance.

Hello,

I am using a Rad Grid control inside of a Rad Pane, Static Headers and Scrolling are enabled. I want it to resize with the rest of the browser window, but unfortunately it only uses about 10% of the Pane when I set any non-static height (it doesn't change anything if I use 10% or 100%). I have tried using the code found under the following URL:
http://www.telerik.com/community/code-library/aspnet-ajax/grid/setting-100-height-and-resize-on-container-resize-for-grid-with-scrolling-and-static-headers.aspx
as suggested in various threads regarding this topic, but it only makes my Grid too high when the page is first loaded (scroll-bar disappears at the end of the page when scrolling), and resizes it to use, again, about 10% of the overall site once the browser-window is resized.
Is there a possible solution for this?

Thanks in advance,
Robin

Hi, I've installed the control panel, but it's not appearing in Start-Programs or the desktop, not even in add/remove software. So how can I make a shortcut to the desktop then?

Also, some other posts mentioned about company wide installation which is also good to have.
In addition, a version selector for control panel will be great to have feature, as the project may not be always with the latest version or found problem with the latest version and revert back.

I'm posting this to see if anyone has accomplished this.  I have been trying for a couple of days and am ready to give up.
I have a RadFileExplorer and have added a custom context menu item called Download.  This button action will Download a file or folder from the server to the client computer.  If the download is a folder I zip up the contents of that folder first and then present the download using Response.TransmitFile.  Pretty straight forward.  The problem comes that when you select a folder that is large the zip process may take a while.  I want to notify the client of the progress.  I am already using the RadProgressArea for the Upload control of the RadFileExplorer so I have AllowCustomProgress set to false in the web.config so that it won't show up when selecting the Download. 

Below is my code for the download click client event:

 

function extendedFileExplorer_onGridContextItemClicked(oGridMenu, args) {

 

 

var menuItemText = args.get_item().get_text();

 

switch (menuItemText) {

 

case "Download":

extendedFileExplorer_sendItemsPathsToServer();

 

break;

 

case "Share":

 

var fExplorer = $find("<%= RadFileExplorer1.ClientID %>");

 

var item = fExplorer.get_selectedItem();

 

var owindow = window.radopen("ShareResource.aspx?path=" + item.get_path(), "ShareResourceWindow");

 

return false;

 

break;

}

}

 

function extendedFileExplorer_sendItemsPathsToServer() {

 

var oExplorer = $find("<%= RadFileExplorer1.ClientID %>"); // Find the RadFileExplorer ;

 

var selectedItems = oExplorer.get_selectedItems(); // Retrieve the selected items ;

 

var selectedItemsPaths = extendedFileExplorer_combinePathsInAString(selectedItems); // Get the paths as a string in specific format ;

 

var hiddenField = $get("<%= ctlHiddenField.ClientID %>"); // Find the hiddenField

hiddenField.value = selectedItemsPaths;

__doPostBack(

 

"<%= btnDownload.UniqueID %>", ""); // Call the 'btnDownload_Click' function on the server ;

}

 

function extendedFileExplorer_combinePathsInAString(arrayOfSelectedItems) {

 

var itemPaths = new Array();

 

for (var i = 0; i < arrayOfSelectedItems.length; i++) {

 

// Pass all the selected paths ;

itemPaths.push(arrayOfSelectedItems[i].get_path());

}

 

// Return a string that contains the paths ;

 

return itemPaths.join("|");

}

So this fires off the btnDownload button click event on the server.  From there I am using the DotNetZip library which has tons of progress feedback events that I can access.  So I need to notify the client of some of those events like which file is compressing and total percentage completed.  Has anyone ever tried something like this and made it work?

Thanks,
Adam

I have a page with a grid and when the datasource the grid is bound to has no rows, when the grid displays the filter boxes are not displayed.  A checkbox on the page where the grid is displayed can be checked by the user which then creates a new datasource that does have rows based on a different search criteria and the grid redisplays but the filter boxes are not shown and thus the grid rows cannot be filtered.  Is there a way to force the display of the filter boxes after the datasource is refreshed?

I have a RadDateTimePicker which in edit mode you may want to set text to nothing e.g. select the date string and press delete button on your keyboard. However the date is still present so i can't find out if user has deleted the text or not. How do i do that?

Basically i need to find out if RadDateTimePicker.Text = String.Empty and set the SqlParameter value to DbNull.Value

Thank you so much

I have an issue with formviews being nested inside the templatecolumn of a radGrid and the whole thing is wrapped in an updatepanel.
A dropdown list refreshes data inside the template columns on index changed, and performs a databind on each formview found in each row.
If the dataitemcount of the formview is 0 it goes to insert which works fine.

The problem is when changing the mode to insert on the formview, it will NOT go back to readonly mode even when there is data.  I'm getting double ups in the database from users thinking there's no data.  I'm getting no errors reported by the system.  It just won't pick up the dataitemcount going to 1.
I can force it to readonly in the script, but I can't get it to changemode using dataitemcount any more.

I'm doing the formview refresh using the following code contained in a dropdown_selectedindexchanged function.

        foreach (GridDataItem ri in RadGrid1.Items)
        {
            Label Label1 = (Label)ri.FindControl("Label1");
            Label1.Text = DropDownList2.SelectedItem.Text;
            FormView fw1 = (FormView)ri.FindControl("fw1");
            fw1.DataBind();

            if (fw1.DataItemCount> 0)
            {
                
            }
            else
            {
                fw1.ChangeMode(FormViewMode.Insert);
            }
}


any ideas how I can get it to change back??

I have a client asking to have an Export Excel button appear outside of the RadGrid. Is it possible in this scenerio for the button to call the RadGrid's built-in functionality of exporting to Excel? If so, how can I achieve this?

Thanks,

Hello,

Using Telerik.Web.UI_2011_3_1305
I have a SQL Server table with approx 600,000 records and 28 columns. I created an ASP.Net page with a RadGrid set-up in "Grid / Virtual Scrolling and Paging" as described in the article at:  
http://demos.telerik.com/aspnet-ajax/grid/examples/client/virtualscrollpaging/defaultcs.aspx
(see code below)
However the performance is poor: loading a new grid page takes a very long time, approx 30 seconds...

Please also note the following:
- the SQL Server database is hosted on the same machine
- the development machine is very fast and has 6GB of RAM
Therefore it is not the environment that causes the performance issue.

Please advise.
Regards,
M.R.

I have a web page that is a list of reports.  I use a RadWindow to get the user to enter parameters for the report.  Is it possible to get the RadWindow to open a new browser window that is active?  I'm using the javascript below which opens the report in a new window but it ends up behind my report selection window.



I think what's happening is the RadWindow opens the new browser window then closes and the focus reverts back to the parent window.  End result is the new browser window opened for the report is behind my report selection window.  I'd live to have the new window appear on top as the active window.  Any ideas?
