Hi, we are consdiering purchasing your UI for ASP.net packages.

I reviewed your ASP.net AJAX demo and came across the image editor control which seems like a control we would like to use and customize.

I saw there is an option to draw circles/rectangles, is there an option to edit their coordinates after they are drawn? is there an option to draw programmatically?

Thanks,

Oren

Hiding or making it un-checkable options of columns menu in Context Menu on Radgrid

Hi ,

We are using radgrid menu and we don't want users to un-check all columns from columns menu of context menu.

Is there a way to hide or stop user unchecking some columns of columns menu item?

I tried this below code:

void HeaderContextMenu_ItemCreated(object sender, RadMenuEventArgs e)
{
if (e.Item.Value.Contains("Reference#") && e.Item.Controls.Count > 0)
(e.Item.Controls[0] as CheckBox).Enabled = false;
}

It will make readonly for that column option on first load, but once i un-check another column, it will get enabled for check/uncheck.

Is there any other way to achieve this?

Thanks

Prevent Auto Rebinding of Grid

We are using a rad grid with edit form that opens in popup on the Edit event of each row. Currently grid refreshes each time the edit link is clicked and take time to open the Popup which is impacting the performance. Moreover if we cancel or close the popup
(handled by cancel event) the grid again refreshes and this action also takes time which in fact should be immediate.

Is there anyway to control the rebind of grid on these events.
Structure of grid:
<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">
    <AjaxSettings>
        <telerik:AjaxSetting AjaxControlID="radGridComingSoon">

I am using a stored procedure to to my updates and have this C# code:

protected void gvMembers_UpdateCommand(object sender, GridCommandEventArgs e)

{

var editableItem = ((GridEditableItem)e.Item);

var memberId = (int)editableItem.GetDataKeyValue("UserID");

int Role = 1;

CheckBox active = (CheckBox)editableItem["valid"].Controls[0];

Boolean bactive = Convert.ToBoolean(active);

string str = active.Text;

string strFirstName = (editableItem["firstname"].Controls[0] as TextBox).Text;

string strLastName = (editableItem["lastname"].Controls[0] as TextBox).Text;

string strUserName = (editableItem["username"].Controls[0] as TextBox).Text;

string strEmail = (editableItem["firstname"].Controls[0] as TextBox).Text;

try

{

//save chanages to Db

DbContext.AAHomicideLogMembersUpdate(memberId, Role, strFirstName, strLastName, strUserName, strEmail, active);

}

catch (System.Exception)

{

string srtt="Dosomething";

}

I get an error message when attempting to convert the checkbox value to a boolean value.

How can I accomplish this?

Radgrid loading takes too long - Ajaxifying Radgrid

Hi,

I am having Radgrid in a div (div1) and other controls in another div (div2) on toggle (hide/show) based structure.

I want to show the div2 initially. problem is page is rendering after completion of Radgrid databind only.

I want to load the data to Radgrid without taking too long. may be ajaxifying the load.

Is it possible to show the controls in div2 before completing data loading of Radgrid??

Thanking you,

ComboBox selecteditem dataitem null

I'm using a RadComboBox and would like to get the selected item that was bound to the combobox instead of the selected value, index or text. I can do that with RadGrid but when I try to do it with a ComboBox the selected item's dataitem is always null.

RadGrid:

Event thisEvent = new Event();

thisEvent = (Event)e.Item.DataItem;

thisEvent is now the bound record of type Event.

RadComboBox:

List<BWGroup> individuals = new List<BWGroup>();

individuals = _bwContext.BWGroups.Where(x => x.IsActive == true).OrderBy(x => x.BWGroupName).ToList();

IndividualsRadComboBox.DataTextField = "BWGroupName";

IndividualsRadComboBox.DataValueField = "BWGroupID";

IndividualsRadComboBox.DataSource = individuals;

IndividualsRadComboBox.DataBind();

//After event is fired
