RadComboBox lost data after postback (combo filled by javascript)

RadComboBox data lost on postback.

<telerik:RadComboBox ID="cmbCustOfficeCountry" runat="server" Width="153px" TabIndex="13"
                    AutoPostBack="false" OnClientSelectedIndexChanged="FillOfficeState" EnableViewState="true">
                </telerik:RadComboBox>
//javascript code to fill combobox.(By JSON Method)

function LoadCountry(countryId, countryName, countryDDL) {

    try {

        countryControl = countryDDL;

//call web service method to get all country list from database.

        GetData.GetCountry(countryId, countryName, OnCountryLoaded);

    }

    catch (e) {

        radalert("Error :- on Method:- 'LoadCountry' Description:- " + e.description);

        return false;

    }

}

function OnCountryLoaded(result) {

    try {

        countryControl.get_items().clear();

        countryControl.commitChanges();

        comboItem = new Telerik.Web.UI.RadComboBoxItem();

        comboItem.set_text("Select");

        comboItem.set_value("0");

        countryControl.get_items().add(comboItem);



        for (var rowIndex = 0; rowIndex < result.rows.length; rowIndex++) {

            var rows = result.rows[rowIndex];

               comboItem = new Telerik.Web.UI.RadComboBoxItem();

                comboItem.set_text(rows.CountryName);

                comboItem.set_value(rows.CountryID);



                countryControl.trackChanges();

                countryControl.get_items().add(comboItem);



        }

        var item = countryControl.findItemByText("Select");

        if (item) {

            item.select();

        }

    }

    catch (e) {

        radalert("Error :- on Method:- 'OnCountryLoaded' Description:- " + e.description);

        return false;

    }

}

When ever page goes to postback all radcombo is clear with blank value. I mean the radcombo lost all the data.

Note: I am using webusercontrol, I mean My radcombobox is on my user control not on page.

So, Could you please give me solution to overcome this problem as soon as possible.

Pasting bulleted list from Word in IE 11

Hello,

When I'm pasting the text with a bulleted list from Word in IE 11 the </li> </ul> tags are moved to the end of text and paragraphs below the list are aligned as list items. In Chrome and FF everything is ok. Please,see the attached screenshots.

I've tried several StripFormattingOptions, but it didn't help. The issue also doesn't depend on new lines mode.

Did anyone experience this problem or have any ideas how to fix it?

Thank you.

Kind regards,

Kateryna

Batch Update Question

We're building a proof-of-concept using this Telerik example:

http://demos.telerik.com/aspnet-ajax/grid/examples/data-editing/batch-editing/defaultcs.aspx

I've got the databound ok, however cannot get the update functionality to work at all.

Since the example is shown using a design-time datasource, we're having difficulty figuring out how to set up the update functionality for the grid since it is being bound at runtime.

I'm also using a demo version, so I am not well-acquainted with your controls, however have been developing ASP.Net web forms pages for over 10 years..

Code files are attached.

Thanks

Sorting template column, which has dynamic header text

Hey All,

I have a RadGrid with template columns where I have checkboxes and textboxes. I want to provide sorting on these columns. The problem these columns have Dynamic header text, returned from function. According to some of the threads I read, Dynamic Headertext prevents sorting.

I tried

1. <HeaderText> <% GetHeaderText("Column1") %></HeaderText>

2. On ItemCreated event, if item is HeaderItem, set item["Column1"].Text = GetHeaderText("Column1")

Can I perform sorting on a template column which has dynamic header text?

Thanks.

Jimmy.

Drag & Drop and Context Menus - Menu Won't Stay OPen

I am doing a drag and drop from a grid onto the treeview. All is well, events are hooking up and I am getting all the data I need to make it work. But I have one issue. After the row from the grid is dragged on to the treeview node, I display a context menu that will allow the user to select the action they would like to perform with the dragged item on the node.

I have the context menu showing in the correct place, however it quickly closes again so that the user cannot select any of the menu items.

The code which show the menu:

function onRowDropping(sender, args) {

if (currentNode) {

//Check to see if this is a valid drop

var draggedrow = args.get_draggedItems()[0];

var dragedentitytype = draggedrow.getDataKeyValue('EntityID');

var dragentityid = draggedrow.getDataKeyValue('cplID');

var dropenitytype = currentNode.get_attributes().getAttribute('EType');

args.set_cancel(true); //Cancel the drop, will be handled by menu item, also prevent grid from auto refreshing

var tree = $find("<%=RadTreeStandards.ClientID %>");

currentNode.set_selected(true);

tree._contextMenuNode = currentNode;

var menu = tree.get_contextMenus()[1];

menu.show(args.get_domEvent());

}

else {

args.set_cancel(true);

}

var currentNode = null;

function onNodeMouseOver(sender, args) {

//gets the node upon mousing over the node

currentNode = args.get_node();

}

function onNodeMouseOut(sender, args) {

//resets the currentNode value upon mousing out

currentNode = null;

}

It seems that some event is occurring that I can't cancel that closes the menu?

Thanks,
