RadEditor event handling causing exception in Chrome

Hello,

This bug seems to be specific to Chrome. I'm currently using Chrome version 21.0.1180.79 m. RadEditor seems to be hijacking event handling to cause an exception in RadSplitter. The error that I'm getting is "Uncaught TypeError: Cannot read property 'tagName' of null". It's taken me a bit to narrow it down, but the following code reproduces. I'm using Telerik.Web.UI version 2011.3.1115.35

Steps to reproduce this error:
1. Click on the RadEditor to give it focus.
2. Try to slide the RadSplitter

Results: The split bar moves faster than your cursor. See stack trace below.

How To prevent adding new entries

Using InputType ="Text" mode it automatically allows adding new entries that don't exist in the datasource.
How do I turn this off?

In the documentation (http://www.telerik.com/help/aspnet-ajax/autocompletebox-items-selection.html) it talks about it being off automatically for InputType="Token", but no help for InputType ="Text"
.

ReBind ComboBox from DataGrid when in Insert Mode

Hi, I have a RadGrid bringing data back from the database. When I add a new Item I have several ComboBoxes. The first is populated when the EditForm opens. I next want to bind the next ComboBox with the selected value of the first ComboBox when the selected value changes. How do I do it?

I have another 3 ComboBoxes (not shown yet) that will continue in the same way as each selected value changes.

DetailTable with NestedView Template inside - is it possible?

Hi,

I want a RadGrid with expand/collapse functionallity.
When expanding a selected row, I want to display another RadGrid with the same functionallity, but I want to display image or some data (not a table or grid).

I read about hirarchical grids, and I need something like a grid with detailtable that has nestedview template.
Is it possible to do something like this?
Is there an implementation for expand/collapse in DetailTable?
How can I call itemcreated function for the DetailTable?

Is there any example for something like this?

Thanks!

"No records to display. " is not shown after rebinding empty data source to grid from client side

Team,

I am removing all data rows of grid from client side.
I wanted to show

"No records to display."

in grid.
But it does not shows empty row which contains "No records to display".
Please let me know from where I can set this empty row message from clientside?
Following is my code.
This code works if grid doesn't contain any data but if grid contains the data then it removes the row from the grid but doesn't show
"No records to display".

var mastertableview = objgrid.get_masterTableView();

mastertableview.set_dataSource({});

mastertableview.set_virtualItemCount(1);

mastertableview.dataBind();

Regards,
Sampada

Issue with hiding grid

I have a scenario as below.
There are 3 check boxes.3 textbox associated with each.Grid gets populated on entering a search value in the textbox.On selecting a row on this grid,I need to hide the grid and selected value(one column) is populated into another textbox.I am getting "Object reference not set to an instance of an object.",when I implementing the logic for hiding the grid.Checkbox checked,value entered in search textbox,grid is populated ,a row selected,second textbox populated with grid value,grid gets hidden--> after this process repeated for 2-3 times,again checking on a check box gives the error.
Please find the markup with above controls.

<table width="500px">

<tr>

<td>

<fieldset id="fssearch" runat="server">

<legend>Search </legend>

<table>

<tr>

<td>

<asp:CheckBox ID="CBFile" runat="server" Text="File No" OnCheckedChanged="CBFile_CheckedChanged"

</HeaderContextMenu>

</telerik:RadGrid>

</td>

</tr>

</table>

</fieldset>

</td>

</tr>

</table>

On selecting a row on the grid,I am populating name column value to a textbox and hiding the grid as below.

protected void gvPatientList_SelectedIndexChanged(object sender, EventArgs e)

{

GridDataItem RegId = gvPatientList.SelectedItems[0] as GridDataItem;

string regid = RegId.GetDataKeyValue("pt_regid").ToString();

foreach (GridDataItem dataItem in gvPatientList.Items)

{

if (dataItem.Selected)

{

RCFName.Text = dataItem["pt_name"].Text;

}

gvPatientList.Visible = false;

}

Above mentioned checkboxes act like radio buttons and javascript for the same is as below

<script language="CS" runat="server">

private void makeRadioGroupFromCheckBoxes(IEnumerable<CheckBox> checkBoxes)

{

StringBuilder sb = new StringBuilder();

foreach (CheckBox cb in checkBoxes)

{

foreach (CheckBox innercb in checkBoxes)

{

if (innercb != cb)

{

sb.Append("document.getElementById('");

sb.Append(innercb.ClientID);

sb.Append("').checked = false;");

}

cb.Attributes["onclick"] = "if(this.checked){" + sb.ToString() + "}else{this.checked = true;}";

sb = new StringBuilder();

}

protected void Page_Load(object sender, EventArgs e)

{

if (!Page.IsPostBack)

{

this.makeRadioGroupFromCheckBoxes(new CheckBox[] { CBFile, CBname, CBMobile });

}

Grid gets populated on textchanged event and 'onkeyup="KeyUp();' function of the textbox,associated with it as below.
aspx:

<telerik:RadCodeBlock ID="RadCodeBlock1" runat="server">

<script type="text/javascript">

var timer = null;

function KeyUp() {

if (timer != null) {

clearTimeout(timer);

}

timer = setTimeout(LoadTable, 500);

}

function LoadTable() {

$find("<%= RadAjaxManager1.ClientID %>").ajaxRequest("FilterGrid");

}

</script>

</telerik:RadCodeBlock>

code behind:

protected void RadAjaxManager1_AjaxRequest(object sender, Telerik.Web.UI.AjaxRequestEventArgs e)

{

if (e.Argument.IndexOf("FilterGrid") != -1)

{

gvPatientList.Rebind();

}

protected void RTFileS_TextChanged(object sender, EventArgs e)

{

if (!string.IsNullOrEmpty(RTFileS.Text))

{

_scheduleService = new ScheduleService();

clsSchedule clsschedule = new clsSchedule();

string search = " where OldRegnNo like '" + RTFileS.Text + "%" + "'";

gvPatientList.DataSource = _scheduleService.GetAllPatients(search);

//gvPatientList.MasterTableView.Rebind();

gvPatientList.Rebind();

}

On checkedchanged eveent of check boxes,I am making the grid visible.

protected void CBFile_CheckedChanged(object sender, EventArgs e)

{

if (CBFile.Checked)

{

RTFileS.Visible = true;

gvPatientList.Visible = true;

gvPatientList.MasterTableView.Visible = true;

gvPatientList.Rebind();

}

else

{

RTFileS.Visible = false;

}

Ajaxmanager is as below:

<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server" OnAjaxRequest="RadAjaxManager1_AjaxRequest">

<AjaxSettings>

<telerik:AjaxSetting AjaxControlID="gvPatientList">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="gvPatientList" LoadingPanelID="RadAjaxLoadingPanel1" />

<telerik:AjaxUpdatedControl ControlID="RCFName" />

<%--<telerik:AjaxUpdatedControl ControlID="CBFile" />

<telerik:AjaxUpdatedControl ControlID="CBname" />

<telerik:AjaxUpdatedControl ControlID="CBMobile" />--%>

</UpdatedControls>

</telerik:AjaxSetting>

<telerik:AjaxSetting AjaxControlID="RadAjaxManager1">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="gvPatientList" LoadingPanelID="RadAjaxLoadingPanel1" />

</UpdatedControls>

</telerik:AjaxSetting>

I hope hiding/unhiding the grid gives me the error.Please suggest your ideas on this.
Thanks,

Strange Ajax Behavior with Radbutton RadAjaxPanel RadAjaxManagerProxy RadAjaxManager RadScriptManager

I am having the hardest time getting a RadButton to invoke a function in the code-behind file, which updates the text of the RadButton. So far I can get the button to fire with Ajax, but even though the function changes the text it is not reflected back onscreen. Furthermore, the 2nd time I click the button the page conducts a postback resulting in a view that only shows the contents of the master page. The content of the web form is blank.

Am I missing or have incorrect parameters?

Web Form RadAjaxPanel + RadButton

<telerik:RadAjaxPanel ID="Panel_MyList" RestoreOriginalRenderDelegate="true" LoadingPanelID="RadAjaxLoadingPanel_MyList" runat="server">

<telerik:RadButton UseSubmitBehavior="true" AutoPostBack="true" EnableAjaxSkinRendering="false" EnableEmbeddedSkins="false" EnableTheming="false" EnableBrowserButtonStyle="false" EnableEmbeddedBaseStylesheet="false" ButtonType="LinkButton" ID="Button_MyList" OnClick="Button_MyList_OnClick" runat="server" Text="Add to Favorites" CssClass="btn btn-view" style="font-size:18px;"></telerik:RadButton>

</telerik:RadAjaxPanel>

<telerik:RadAjaxLoadingPanel ID="RadAjaxLoadingPanel_MyList" runat="server" />

Web Form RadAjaxManagerProxy

<telerik:RadAjaxManagerProxy ID="RadAjaxManagerProxy_Tour" runat="server">

<AjaxSettings>

<telerik:AjaxSetting AjaxControlID="Button_MyList" EventName="Click">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="Button_MyList" />

</UpdatedControls>

</telerik:AjaxSetting>

</AjaxSettings>

</telerik:RadAjaxManagerProxy>

Master Page RadScriptManager + RadAjaxManager

<telerik:radscriptmanager ID="Radscriptmanager1" EnablePartialRendering="true" EnablePageMethods="true" ScriptMode="Debug" runat="server"></telerik:radscriptmanager>
<telerik:RadAjaxManager ID="RadAjaxManager1" EnableAJAX="true" runat="server" />
