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;

}

Client-sice template items

Hi,

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);

}

catch (err) { }

}

combo.commitChanges();

}

Thanks for help.

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.

Compilation Error

how to get name of item from item index of rad rotator

Hi,
I'm using the rad rotator for displaying the latest 10 images by using their names from database, where the images are in a folder.
the code for above procedure is below

<telerik:RadRotator ID="RadRotator1" runat="server" Height="120px" Width="680px" ScrollDuration="500" ScrollDirection="Right" FrameDuration="1500" ItemWidth="120px" ItemHeight="100px" RotatorType="AutomaticAdvance" DataSourceID="SqlDataSource1" OnInit="RadRotator1_Init">

<ItemTemplate>

<asp:Image ID="image1" runat="server" CssClass="image" ImageAlign="left" Visible="true" ImageUrl='<%# String.Format("~/upload data/movies/{0}", DataBinder.Eval(Container.DataItem, "imagename")) %>' />

</ItemTemplate>

</telerik:RadRotator>

<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:cinema mistakesConnectionString %>"

SelectCommand="SELECT TOP 10 [imagename] FROM [movie] ORDER BY [mid] DESC"></asp:SqlDataSource>

when a client clicks on the rotator item (image) it is redirecting to the new page, code for this is below

protected void RadRotator1_Init(object sender, EventArgs e)

{

RadRotator1.ItemClick += new RadRotatorEventHandler(RadRotator1_ItemClick);

GridNumericColumnEditor throwing ArgumentOutOfRangeException error

We have a grid that uses a series of numeric columns. For consistency, the developer was attempting to use a GridNumericColumnEditor; this works properly when it's applied to a single column, but when it's applied to more than one column the page throws a ArgumentOutOfRangeException when attempting to edit.

The column editor is defined as;

<telerik:GridNumericColumnEditor ID="customNumeric" runat="server"><br>

<NumericTextBox Width="70" /><br>

</telerik:GridNumericColumnEditor>

...and the Grid columns are defined as;

<

telerik:GridNumericColumn DataField="Area1" DataType="System.Decimal" HeaderText="Area1"<br>

SortExpression="Area1" UniqueName="Area1" NumericType="Currency" DataFormatString="{0:c2}"<br>

Aggregate="Sum" ColumnEditorID="customNumeric"><br>

</telerik:GridNumericColumn><br>

<telerik:GridNumericColumn DataField="Area2" DataType="System.Decimal" HeaderText="Area2"<br>

SortExpression="Area2" UniqueName="Area2" NumericType="Currency" DataFormatString="{0:c2}"<br>

Aggregate="Sum" ColumnEditorID="customNumeric"><br>

</telerik:GridNumericColumn>

If we have the ColumnEditorID set in only one column (any column) it works, but when it's added to the second or subsequent column it throws the error. Is there something we're missing?

Grid
