access GridDropDownColumn in RADGRID using Javascript

Hello,
I want to access GridDropDownColumn of RADGRID using Javascript. I know how to create function on ItemDataBound and access the GridDropDownColumn from there. But my javascript function is being called from the other page. And from the other page I want to access the GridDropDownColumn which has Dropdown in the EDIT mode in the RADGRID.
I want to set the value passed from the other page to set the GridDropDownColumn's dropdown's value.
Please help me fresolving this problem.
Telerik contols have problem accessing from javascript without using the server side code. Please put attention to my POST and reply me ASAP.

Thanks,
Deepa

RadMenu not working in RadTreeView within XMLHttpPanel

- The RadXmlHttpPanel currently contains a RadTreeView, which has a context menu defined using RadTreeViewContextMenu.
- The EnableClientScriptEvaluation property of RadXmlHttpPanel has been set to true, but the client side event 'OnClientContextMenuItemClicking' of the RadTreeView doesn't seem to fire while 'OnClientContextMenuShowing' event fires.
- Have also tried by setting RegisterWithScriptManager property of RadTreeView to false, this still doesn't help

Snippet:
----------
<telerik:RadXmlHttpPanel ID="RadXmlHttpPanel1" runat="server" OnServiceRequest="XmlHttpPanel_ServiceRequest" OnClientResponseEnded="XmlHttpPanel_ResponseEnded"
EnableClientScriptEvaluation="true" RenderMode="Block">
<telerik:RadTreeView ID="treeView1" runat="server" OnNodeDataBound="treeView1_NodeDataBound"
EnableViewState="false" OnClientContextMenuItemClicking="onClientContextMenuItemClicking" OnClientContextMenuShowing=”onClientContextMenuShowing”
Height="99%" RegisterWithScriptManger="false">
<ContextMenus>
<telerik:RadTreeViewContextMenu ID="MainContextMenu" runat="server">
<Items>
<telerik:RadMenuItem Value="menuItem1" Text=" menuItem1" AccessKey="M">
</telerik:RadMenuItem>
<telerik:RadMenuItem Value="menuItem2" Text=" menuItem2" AccessKey="U">
</telerik:RadMenuItem>
</Items>
<CollapseAnimation Type="none" />
</telerik:RadTreeViewContextMenu>
</ContextMenus>
<NodeTemplate>
<asp:CheckBox ID="NodeCheckBox" runat="server"></asp:CheckBox>
<asp:RadioButton ID="NodeRadioButton" runat="server"></asp:RadioButton>
</NodeTemplate>
</telerik:RadTreeView>
</telerik:RadXmlHttpPanel>

Here, onClientContextMenuItemClicking doesn’t get hit, while onClientContextMenuShowing is hit.

Parent node always checked in NodeCheck event handler when using TriStateCheckboxes?

Want to make sure I understand how this is supposed to work.

When my RadTreeView is not configured to use TSCB, on postback, in the NodeCheck event handler, e.Node.Checked returns the new value of the check state (true if checked, false otherwise). If true == e.Node.Checked, I check all child nodes; if not checked, I uncheck all child nodes.

However, when I enable TSCB, on postback, in the NodeCheck event handler, e.Node.Checked is always true, even if the node was already checked and the event fired because I unchecked it.

What am I missing?

Thanks

Multiple selection with checkboxes

Hello,

I would like to handle multiselection in RadGrid on server side, but not by storing the selected item during every selection/deselection like in the sample http://www.telerik.com/help/aspnet-ajax/grdpersistselectedrowsonsorting.html, but storing them only during sorting, paging, filtering and some custom commands. I have added a GridClientSelectColumn to my MasterTableView columns, so the graphical handling of the multiselection on one page works fine. But if I would like to get in the OnItemCommand handler of the grid(after paging, sorting or RadGrid.DeleteSelectedCommandName), whether the checkbox of a row(DataItem) is checked or not, I can not get this information. The returned states of the checkboxes are always false. Could you suggest a way, how can I get/set the selected state of a row in this case?

I don’t want to have callbacks by every (de)selection, although no EnablePostBackOnRowClick=true and RadGrid.SelectCommandName/RadGrid.DeselectCommandName or GridTemplateColumn with AutoPostBack=true. I could not solve the problem with GridTemplateColumn and AutoPostBack=false and another problem of this case, that the graphical part of the selection is not automatically solved.

Thanks:

Zoltán

My checkbox is in the third column. I get the state of the checkbox with the following:

bool selected = (dataItem.Cells[2].Controls[0] as CheckBox).Checked;

My RadGrid definition:

<telerik:RadGrid ID="RadGridFiltered" runat="server" Skin="WebBlue"

AllowSorting="true" AllowPaging="true" AllowMultiRowSelection="true" PageSize = 10

OnItemCommand="RadGridFiltered_OnItemCommand" OnPreRender="RadGridFiltered_PreRender">

<asp:LinkButton ID="btnEditSelected" runat="server" CommandName="EditSelected" Visible='<%# RadGridFiltered.EditIndexes.Count == 0 %>'><img style="border:0px;vertical-align:middle;" alt="" src="Images/Edit.gif" />Kijelölt módosítása</asp:LinkButton>  

</div>

</CommandItemTemplate>

<telerik:GridClientSelectColumn UniqueName="ClientSelectColumn" />

</Columns>

</MasterTableView>

</ClientSettings>

</telerik:RadGrid>

My selection store handler:

    public void RadGridFiltered_OnItemCommand(object sender, GridCommandEventArgs args)
    {
        StoreSelectedItems();

.........

}

const string SessionSelectedItems = "SelectedItems";

const string KeyName = "RETURN_ID";

protected void StoreSelectedItems()

{

ArrayList selectedItems = (Session[SessionSelectedItems] != null) ? (ArrayList)(Session[SessionSelectedItems]) : new ArrayList();

foreach (GridDataItem dataItem in RadGridFiltered.MasterTableView.Items)

{

bool selected = (dataItem.Cells[2].Controls[0] as CheckBox).Checked; // ALWAYS FALSE !!!

dataItem.Selected = selected;

string id = dataItem.OwnerTableView.DataKeyValues[dataItem.ItemIndex][KeyName].ToString();

if (selected && !selectedItems.Contains(id))

selectedItems.Add(id);

else if (!selected && selectedItems.Contains(id))

selectedItems.Remove(id);

}

Session[SessionSelectedItems] = selectedItems;

}

I have empty combobox with template created on server side.
I need add item with javascript on client-side, but I need use template items (checkbox)
If I add new item, I have only clasic combobox item.

class CheckBoxTemplate : ITemplate

{

string ColName = "cboCol1";

const string head = "<div onclick=\"StopPropagation(event)\">";

const string tail = "</div>";

public void InstantiateIn(Control container)

{

CheckBox chkControl = new CheckBox();

chkControl.ID = "chkControl";

chkControl.CssClass = "";

chkControl.Attributes.Add("onclick", "onCheckBoxClick('" + _controlClientId + "')");

chkControl.DataBinding += new EventHandler(this.chkControl_DataBind);

container.Controls.Add(new LiteralControl(head));

container.Controls.Add(chkControl);

container.Controls.Add(new LiteralControl(tail));

}

public void chkControl_DataBind(Object sender, EventArgs e)

{

CheckBox chkControl = (CheckBox)sender;

RadComboBoxItem radComboItem = (RadComboBoxItem)chkControl.NamingContainer;

chkControl.Text = " " + DataBinder.Eval(radComboItem.DataItem, ColName).ToString();

}

Javascript add items

var xmlDoc = xmlDoc.firstChild;

if (xmlDoc.childNodes.length > 0) {

var combo = $find(comboid);

combo.trackChanges();

for (x = 0; x < xmlDoc.childNodes.length; x++) {

try {

sCboID = xmlDoc.childNodes[x].childNodes[0].childNodes[0].nodeValue;

sCboText = xmlDoc.childNodes[x].childNodes[1].childNodes[0].nodeValue;

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

comboItem.set_text(sCboText);

comboItem.set_value(sCboID);

combo.get_items().add(comboItem);

Malfunctioning Intellisense After Update

I received an incomplete project utilising Telerik controls after a coworker left our company.
After installing the latest version of Telerik, I loaded the project and encountered a few initial errors with controls not rendering.
The project previously made use of Telerik:RadScriptManager which I had to change to the asp:ScriptManager in order to get the project to render and compile. I had it working until yesterday when Visual Studio '08 was no longer able to supply File, Line, Column, or Project Information on code errors. Additionally, ASP.NET error pages (YPODs) are also unable to supply data on errors - only supplying the following:

Server Error in '/MyProject' Application.
