Hi. I want to commend you on making OrgChart control, it's a lot of fun to work with.

We use OrgChart in GroupEnabledBinding with GroupColumnCount=1. Problem is with empty Group Nodes that set default size ignoring set CSS styles.

How can We set size of empty Group Nodes? In Node Size demo it's shown how to change size of items, but not of empty Nodes.

Please notice example image in Attachment.

Thank You on Your help.

RadEditor for Sharepoint 2010

I'm having trouble getting the RadEditor to show up in SharePoint 2010.

1) I went through the install of RadControlsForAspNetAjaxSetup_2012_2_607, but no sign of the RadEditor to insert as a Web Part, nor do I get the RadEditor as the default editor for rich text.

So, it must be something simple that I'm missing. I've been through some documentation, searched for steps, issues, ect, they usual beginning trouble shooting.

Can anyone provide me with some thoughts, items to look at, ect.

Jeff.

Error during serialization or deserialization using the JSON JavaScriptSerializer. The length of the string exceeds the value set on the maxJsonLength property

Hello,

I have a web application that uses RadTreeView control for displaying data. When displaying large amount of data, it throws following error:

"Error during serialization or deserialization using the JSON JavaScriptSerializer. The length of the string exceeds the value set on the maxJsonLength property."

I have tried changing "maxJsonLength" property to value 2147483646 in web.config of the application. But still above error appears.
Please help.

Detailed error is as follows:

RedMenu Goes away

I've been using radMenu and radWindow on the same screen.
inspired form :http://www.telerik.com/support/kb/aspnet-ajax/window/show-radwindow-above-radmenu.aspx

actually I'm using an event mouse-out to hide the menu when I do not want:

</script>

<script type="text/javascript" id="telerikClientEvents2">

//<![CDATA[

function RadMenu1_MouseOut(sender, args) {

document.getElementById(sender.get_id()).style.zIndex = -1;

}

//]]>

</script>

but I observed that it works even when I leave the tool-bar and go to the drop down menu, so there any way out where I can actually distinguish if the mouse is on the menu or anywhere else ?

Issue with self-referencing hierarchy grid

I have followed the code provided in the self-referencing hierarchy demo (http://demos.telerik.com/aspnet-ajax/grid/examples/hierarchy/selfreferencing/defaultcs.aspx) exactly, but I am having trouble with the columns in nested details table not lining correctly.

My radgrid looks like this

<style type="text/css">

.RadGrid td

{

padding: 0;

}

</style>

<telerik:RadGrid ID="rgTasks" runat="server" OnNeedDataSource="rgTasks_NeedDataSource"

Skin="Hay"

OnColumnCreated="RadGrid1_ColumnCreated"

OnItemCreated="RadGrid1_ItemCreated" OnItemDataBound="RadGrid1_ItemDataBound">

<MasterTableView CommandItemDisplay="None" DataKeyNames="TASK_UID, TASK_PARENT_UID"

HierarchyDefaultExpanded="true" HierarchyLoadMode="Client">

<SelfHierarchySettings ParentKeyName="TASK_PARENT_UID" KeyName="TASK_UID" />

<NoRecordsTemplate></NoRecordsTemplate>

</MasterTableView>

<ClientSettings AllowExpandCollapse="true" />

</telerik:RadGrid>

However, as you can see from the screenshot, the columns are not aligning as they are in the demo. The code-behind is exactly as in the demo. The only difference is that I am running on .Net 3.5

Entire code behind code is here:

protected void Page_Load(object sender, EventArgs e)

{

rgTasks.MasterTableView.FilterExpression = "TASK_PARENT_UID IS NULL";

}

protected void RadGrid1_ColumnCreated(object sender, GridColumnCreatedEventArgs e)

{

if (e.Column is GridExpandColumn)

{

e.Column.Visible = false;

}

else if (e.Column is GridBoundColumn)

{

e.Column.HeaderStyle.Width = Unit.Pixel(100);

e.Column.ItemStyle.Wrap = false;

}

public void Page_PreRender(object sender, EventArgs e)

{

HideExpandColumnRecursive(rgTasks.MasterTableView);

}

public void HideExpandColumnRecursive(GridTableView tableView)

{

GridItem[] nestedViewItems = tableView.GetItems(GridItemType.NestedView);

foreach (GridNestedViewItem nestedViewItem in nestedViewItems)

{

foreach (GridTableView nestedView in nestedViewItem.NestedTableViews)

{

nestedView.Style["border"] = "0";

Button MyExpandCollapseButton = (Button)nestedView.ParentItem.FindControl("MyExpandCollapseButton");

if (nestedView.Items.Count == 0)

{

if (MyExpandCollapseButton != null)

{

MyExpandCollapseButton.Style["visibility"] = "hidden";

}

nestedViewItem.Visible = false;

}

else

{

if (MyExpandCollapseButton != null)

{

MyExpandCollapseButton.Style.Remove("visibility");

}

if (nestedView.HasDetailTables)

{

HideExpandColumnRecursive(nestedView);

}

protected void RadGrid1_ItemCreated(object sender, GridItemEventArgs e)

{

CreateExpandCollapseButton(e.Item, "TASK_UID");

if (e.Item is GridHeaderItem && e.Item.OwnerTableView != rgTasks.MasterTableView)

{

e.Item.Style["display"] = "none";

}

if (e.Item is GridNestedViewItem)

{

e.Item.Cells[0].Visible = false;

}

protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)

{

CreateExpandCollapseButton(e.Item, "TASK_UID");

}

public void CreateExpandCollapseButton(GridItem item, string columnUniqueName)

{

if (item is GridDataItem)

{

if (item.FindControl("MyExpandCollapseButton") == null)

{

Button button = new Button();

button.Click += new EventHandler(button_Click);

button.CommandName = "ExpandCollapse";

button.CssClass = (item.Expanded) ? "rgCollapse" : "rgExpand";

button.ID = "MyExpandCollapseButton";

if (item.OwnerTableView.HierarchyLoadMode == GridChildLoadMode.Client)

{

string script = String.Format(@"$find(""{0}"")._toggleExpand(this, event); return false;", item.Parent.Parent.ClientID);

button.OnClientClick = script;

}

int level = item.ItemIndexHierarchical.Split(':').Length - 1;

button.Style["margin-left"] = level * 15 + "px";

TableCell cell = ((GridDataItem)item)[columnUniqueName];

cell.Controls.Add(button);

cell.Controls.Add(new LiteralControl(" "));

cell.Controls.Add(new LiteralControl(((GridDataItem)item).GetDataKeyValue(columnUniqueName).ToString()));

}

void button_Click(object sender, EventArgs e)

{

((Button)sender).CssClass = (((Button)sender).CssClass == "rgExpand") ? "rgCollapse" : "rgExpand";

}

Tooltips on a Particular Cell Not Working

I am transitioning code from Microsoft's GridView to Telerik's RadGrid. One thing I'm stuck on is how to add a Tooltip to a particular cell.   did find this article but the advice therein is not working for me: http://www.telerik.com/community/forums/aspnet/grid/radgrid-tooltip-on-cell.aspx

Here's the crux of the code I'm using:

protected void radGrid_ItemDataBound(object sender, GridItemEventArgs e)
    {
      if (e.Item is GridDataItem)
      {
        GridDataItem item = (GridDataItem)e.Item;
        item.Cells[1].ToolTip = "Sample Tooltip";

But, as I said above, no tooltip appears. What should I do instead?

Unable to transfer items added on server side

Hello, I just updated the Telerik controls to version 2012.2.607.35 and it seems that the ability to transfer items between radcomboboxes has changed. I have two radcomboboxes, one with all possible choices and the other with previously selected choices which are loaded during Page_Load. I can add and remove new items to the list of previously selected items, but I am now unable to transfer existing items (added during the Page_Load event) out of it. This had been working prior to installing the new version. If I add a delete button I am able to remove them. I have verified that this isn't caused by any changes I made by updating the Telerik controls in an old project that uses this same structure and recompiling with no other changes, the functionality is then lost.

Can this be fixed, or is there a way I can work around it?

Thanks,
John

Postback while in radgrid edit form mode

Radgrid edit mode rocks with a special formtemplate, it this might be simple but cannot figure out. I need to be able to postback while in edit mode, i have 2 dropdownlists and need the second to be filled by the first while in edit mode. I can fill them to existing values but if a user need to change them they stay with existing values and don't change becuase of no postback. So basically if they pick another make I need the models to refresh themselves based on the make. If this is not possible in edit mode I will take it out to a panel and do it here.

Protected Sub myRadGrid_ItemDataBound(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridItemEventArgs) Handles myRadGrid.ItemDataBound

If (TypeOf e.Item Is GridEditableItem AndAlso e.Item.IsInEditMode) Then

Dim editedItem As GridEditableItem = DirectCast(e.Item, GridEditableItem)

Dim Loc As DropDownList = DirectCast(editedItem.FindControl("ddlLocation"), DropDownList)

Dim make As DropDownList = DirectCast(editedItem.FindControl("ddlMake"), DropDownList)

Dim model As DropDownList = DirectCast(editedItem.FindControl("ddlModel"), DropDownList)

'Get the Location filled

sql = "Select intDurableId, strLocation from Drat_J6DurableInfo Order by strLocation"

Loc.Items.Add(New ListItem("Pick Location", "0"))

buildDD(sql, Loc)

Loc.SelectedValue = DirectCast(DataBinder.Eval(e.Item.DataItem, "intDurableId").ToString(), String)

Loc.DataBind()

'Get the make of the item

sql = "Select intmakeId, strmake from Drat_Make order by strmake"

make.Items.Add(New ListItem("Pick Make", "0"))

buildDD(sql, make)

make.SelectedValue = DirectCast(DataBinder.Eval(e.Item.DataItem, "intMakeId").ToString(), String)

make.DataBind()

'Get the Model of the item

sql = "Select intModelId, strModel from Drat_Model order by strModel"

model.Items.Add(New ListItem("Pick Model", "0"))

buildDD(sql, model)

model.SelectedValue = DirectCast(DataBinder.Eval(e.Item.DataItem, "intModelId").ToString(), String)

model.DataBind()

End If

End Sub
