Get custom objects server side after checking a row

Hi,
I have a grid that is bound to a data source:

<telerik:RadGrid ID="gvVerwendungen" runat="server" PageSize="15"

AllowPaging="True" Width="100%" AutoGenerateColumns="false"

OnNeedDataSource="gvVerwendungen_NeedDataSource" ShowStatusBar="true">

<MasterTableView Width="100%" Summary="RadGrid table" ShowFooter="true">

<Columns>

<telerik:GridTemplateColumn UniqueName="CheckBoxTemplateColumn">

<ItemTemplate>

<asp:CheckBox ID="Auswahl" runat="server" AutoPostBack="True" OnCheckedChanged="Auswahl_ToggleRowSelection" />

</ItemTemplate>

<HeaderTemplate>

<asp:CheckBox ID="headerChkbox" runat="server" AutoPostBack="True" />

</HeaderTemplate>

</telerik:GridTemplateColumn>

<telerik:GridBoundColumn FooterText="Dienststelle" UniqueName="Dienststelle"

HeaderText="Dienststelle" DataField="Dienststelle">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn FooterText="Beginn" UniqueName="Beginn"

HeaderText="Beginn" DataField="Beginn"

DataType="System.DateTime" DataFormatString="{0:dd/MM/yy}">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn FooterText="Sachbezug" HeaderText="Sachbezug"

DataField="Bezug">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn FooterText="Status" UniqueName="VerwendungsStatus"

DataField="VerwendungsStatus">

</telerik:GridBoundColumn>

</Columns>

</MasterTableView>

<PagerStyle Mode="NextPrevAndNumeric" />

</telerik:RadGrid>

In the code behind there is the event code:

protected void gvVerwendungen_NeedDataSource(object source, Telerik.Web.UI.GridNeedDataSourceEventArgs e)

{

if (mitarbeiter != null && mitarbeiter.VerwendungseintraegeAktuelleUndGeplante != null)

{

this.gvVerwendungen.DataSource = mitarbeiter.VerwendungseintraegeAktuelleUndGeplante;

}

This works fine.
For the selection of the row I want to use a checkbox:

protected void Auswahl_ToggleRowSelection(object sender, EventArgs e)

{

((sender as CheckBox).NamingContainer as GridItem).Selected = (sender as CheckBox).Checked;

bool checkHeader = true;

foreach (GridDataItem dataItem in gvVerwendungen.MasterTableView.Items)

{

// Auswahl is the name of the ckeckbox-column

if (!(dataItem.FindControl("Auswahl") as CheckBox).Checked)

{

checkHeader = false;

break;

}

GridHeaderItem headerItem = gvVerwendungen.MasterTableView.GetItems(GridItemType.Header)[0] as GridHeaderItem;

(headerItem.FindControl("headerChkbox") as CheckBox).Checked = checkHeader;

if (gvVerwendungen.SelectedItems.Count > 0)

{

// gvVerwendungen is the name of the grid

GridDataItem dataItem = gvVerwendungen.SelectedItems[0] as GridDataItem;

// Question: How can I get the bound custom object?

// Problem: The custom object has no ID

}

else

{

tbStellenzeichen.Text = "Nothing";

}

My Question: How can I get the custom object instance of the current row?

For a hint, I would be grateful
Kind regards.
Christian

GridEditFormItem editedItem =

(GridEditFormItem)((GridDataItem)e.Item).EditFormItem;

DropDownList ddlBar = (DropDownList)editedItem["BarID"].FindControl("ddlBarID");

Label1.Text = "BarID null: " + (ddlBar == null).ToString();

ddlBar.Items.Add("TEST");

I get Object reference not set to an instance of an object.

update of usercontrol loaded in RadPageView to rebind the associated RadTabStrip?

Hi.

I have a page with several RadTabStrip/RadMultiPage combinations. One of them dynamically loads copies of the same user control (with a parameter from the value of its RadTab) into correlating RadPageViews. I have a 'Delete' button on the contained usercontrol that deletes its specific data. So, then the whole RadTabStrip and PageViews needs to be rebound to reflect the change (which will have one less tab/pageview after the delete). I can do this easily by simply reloading the whole page, but I would like to be more elegant, and do that with ajax. How can a button event on a single PageView's usercontrol locate the containing RadTabStrip, and initiate a rebind via ajax?

Thanks for any help!!

Insert External Video tools' window is too large for page size but no scrollbars are shown

Hi Telerik,
I'm facing the following issue: If "Insert External Video" tool is launched in RadEditor (which itself is displayed in RadWindow), its' buttons are hidden (because of small screen resolution), but no scrollbars are shown (see the image attached). Is there a way how to force the "Insert External Video" tool window to have scrollbars displayed?
Thanks in advance.
Regards

CAPTCHA methods and properties

Hello,

I am new to Telerik. I am struggling with finding a list of methods and properties for the RAD controls.

I can see from intellisense that the controls have a lot to offer.

I was able to find the code samples, I downloaded the "Rad Controls AJAX Courseware", and found other documents online - but I was did not find a list of properties and methods (like the you would find on the MSDN site).

Can someone direct me to the right location please?

Thank you,

Automatic modifications in Rad Editor

I am getting XSL data in the RadEditor with EditMode as HTML in the mark-up. But the Editor is automatically modifying my XSL data and showing it in Rad Editor. I want exact same data to be shown. I tried adding ContentFilter="ConvertToXhtml" but it didn't work.

What should I do to show my XSL data in Rad Editor exactly same as in database?

FYI: I have set Rad Editor in Editmode="HTML" so there is no option of switching modes.

HELP!!!!!!!!!
