Hello,

I am using Radtreeview and attempting to load radtree nodes to memcached. I am receiving the following message:

Type 'Telerik.Web.UI.RadTreeNode' in Assembly 'Telerik.Web.UI, Version=2012.2.1002.40, Culture=neutral, PublicKeyToken=121fae78165ba3d4' is not marked as serializable.

I read in related post that the fix would be in the 2012.2.1002.40 nightly build but I am still receiving the error after upgrading.

Thanks

Mike

Radcombobox enabled/disabled onload via javascript

Hi,

I really need to enabled/disabled the RadComboBox via Javascript when the page is load. I need to do it so I can enable / disable the combobox again when the user click another button via JavaScript. I dont want to postback.

I have put the following code in the Page_Init()

ClientScript.RegisterStartupScript(Page.GetType(),

"mykey", "ToggleRadcomboBox();", true);

The javascript is as follow
function ToggleRadcomboBox()
{
    var combo = $find("<%= RadComboBox1.ClientID %>");
    //the combo return null
    combo.set_enabled(false);
    return false;
}

The above code will return me with "null value",
but, when I used:
function ToggleRadcomboBox()
{
    var combo = document.getElementByID("<%= RadComboBox1.ClientID %>");
    // found combo, but unable to do anything
    // combo.set_enabled(false) does not work when using document.getElementByID
    combo.disabled = true;
    return false;
}

Could you please help me out ?

Thanks.

Strange behaviour on toggle checkbox button with images

I use the following RadButton on a couple of pages and it behave strangely on each page.

<style type="text/css">

.rbBlue .rbText {

color: blue;

}

.rbRed .rbText {

color: red;

}

</style>

<telerik:RadButton ID="FillerNLF" runat="server" AutoPostBack="false" Text="NLF" ButtonType="ToggleButton" checked="false"

ToggleType="CheckBox" Style="font-size: 14px; top: 30px; left: 4px; position: absolute;">

<ToggleStates>

<telerik:RadButtonToggleState PrimaryIconUrl="../Images/layer_transparent.jpeg" CssClass="rbBlue" />

<telerik:RadButtonToggleState PrimaryIconCssClass="rbOk" Selected="true" CssClass="rbRed" />

</ToggleStates>

</telerik:RadButton>

On page 1, I use this and the behavior is fine. When the checkbox is unchecked, the text is blue colored and it is a transparent icon shown. When the checkbox is checked, the green checkmark appears and color of the text is red. That is the proper behavior.

When I use the exact same button on another page, I am getting a square outline of the layer_transparent.jpeg file when it is unchecked. If I hover the mouse over the item, the square outline disappears and nothing is displayed, except the blue text. When the checkbox is checked, a green checkbox appears and the text is red. So, it is the unchecked behavior that is not working. It's for this page only. I noticed this as I am building the page and there is no logic in the codebehind.

[Solved] Reading read only column in ragdrid update

I am using EditMode="InPlace" and AllowMultiRowEdit="True" to edit a RadGrid. I am also using a non RadGrid button to save the RadGrid to a database. Column1 in the RadGrid is read only. I am using ExtractValuesFromItem(newValues, editedItem) to get the cell that was changed. This works, but I don't know how to reference the value in the read only cell in column1 to see which row was edited. I need this to update the database based on the read only information in Column1. I will also be adding databound dropdown lists in the EditItem template so a solution that drastically changes the code below also needs to be able to handle that.

protected void SaveButton_Click(object sender, EventArgs e)

{

foreach (GridItem item in RadGrid1.Items)

{

if (item.IsInEditMode)

{

GridEditableItem editedItem = (GridEditableItem)item;

Hashtable newValues = new Hashtable();

editedItem.OwnerTableView.ExtractValuesFromItem(newValues, editedItem);

// I need to get the value in Column1 on the edited row.

string ReadOnlyCell = ["Column1"].toString();

string ChangedCell = newValues["Column2"].ToString();
