How do I get value (that is checked) from GridClientSelectColumn, and how do I save the ones I selected after a postback?

When i submit i always get dataitem.Selected = false/nothing...

Protected Sub rbFelAnmal_Click(sender As Object, e As EventArgs) Handles rbFelAnmal.Click

For Each item As GridItem In RadGrid1.MasterTableView.Items

Dim dataitem As GridDataItem = DirectCast(item, GridDataItem)

If dataitem.Selected Then

value = value & dataitem.GetDataKeyValue("DateOfBirth").ToString() & "<br>"

Else

End If

Rad Asycn Upload not working on IE 9 or Lower

Hello Forum,

We have been using Rad Asycn Upload to upload the files to the server. The control is working with Chrome and FireFox and IE10. But as we switch to IE9 or Lower versions of Internet Explorer, the control no longer works. Please find the web site project created in reference to the problem that we are facing at our end. Also the screen snaps have been attached with the problem when the file is uploaded to the server on IE9 or IE8. Can anyone please help or guide me through the issue?

Thanks
Bas

How to make particular rows readonly in editable grid ?

Hi,

We are using Telerik RadControls for ASP.NET Ajax version 2013.3.1114.45.
I have a radgrid with GridClientSelectColumn as first column to select rows, a checkbox column and Gridboundcolumn and the grid is in edit mode.
How to make a particular row read-only based on some condition ?

When the row becomes read-only, the following things should happen.
1. GridClientSelectColumn should not be visible for that row.
2. Checkbox should not be displayed, Yes or No text should be displayed instead of a tick-able checkbox
3. Editable textbox in gridboundcolumn should become readonly

Can you please help how to achieve ?

To hide the GridClientSelectColumn for some of the rows based on some condition, I did it as below in ItemDataBound event.
e.Item.Cells[2].Controls[0].visible = false;

But when the user clicks on the row (anywhere in the row), though the clientselectcheckbox is not visible, it is getting selected.
The following property returns true when the clientselectcolumn is not visible in a row and the user just clicked anywhere in the readonly row.

((System.Web.UI.WebControls.CheckBox)(gridDataItem.Cells[2].Controls[0])).Checked

MouseOver tab selection

I am attempting to add mouseover activation of tabs, per the following article:

http://www.telerik.com/help/aspnet-ajax/tabstrip-change-tabs-mouseover.html

I copied the code, the page loads without error, and the tabs change as intended.

However I get "Line: 75 Error: Unable to get property 'selectParents' of undefined or null reference" as soon as the mouse moves out of the tabstrip control..

Running Win 8.1 with I.E. 11 when the error occurs.

No error with Firefox.

I would like to know what this error is and how I might adjust the code to prevent or ignore.

Hide templates on insert?

I'm using a radlistview w/ a pagesize of 1 to simulate a winforms data entry screen for data collection on an ipad.

When I click to have the user add a new record, the current record is displayed at the top of the screen and a second insert record is displayed at the bottom.

Is there a way for me to only show the insertitemtemplate and hide the other templates when doing an insert?

Thanks,
Mike

[Solved] Get Grid ID from event PageSizeChanged

I am trying to make a more generic method to attach to 3 grids on the same page and would like for the PageSizeChanged event to used by all three grids, but have the code inside the event figure out the grid that called the event... I am sure this can be done, but I have not been able to drill down through the sender object to get the ID..

So I took this approach (Does it look safe enough?)...

var Sender = ((RadGrid)sender);
string GridName = Sender.ID;

public void Grid_PageSizeChanged(object sender, GridPageSizeChangedEventArgs e)

{

//get the current page name

string pageName = Path.GetFileNameWithoutExtension(Request.Path);

string GridName = {Here is where I want to use sender to get the actual grid.id}

int newPageSize = e.NewPageSize;

var pagerHelper = new GridPagerSizeHelper();

pagerHelper.saveSelectedPageSize(pageName, GridName, newPageSize, (User)Session["currentUser"]);

var Nav = new Common.MasterPages.Nav();

Nav.ReloadUserPreferences((User)Session["currentUser"]); // To avoid DB hit with each page load.

}

Binding RadPanelBar generates "DataSource not set" since 2014.1.225

I get a "DataSource not set" error when I bind a RadPanelBar.
To reproduce the bug, it must contain a RadPanelItem that contains a RadAutoCompleteBox.
The problem appeared in version 2014.1.225 and is still visible in the hotfix 2014.1.326

protected string RadPanelItemValue = "RadPanelItem1";

protected void Page_Load(object sender, EventArgs e)

{

if (!Page.IsPostBack)

{

RadPanelBar1.DataBind(); // Generates an error: "DataSource not set"

}
