Hi I have a RadCombobox that is Enable Load On Demand - Handled code side.

I've attached an event to the OnClientItemsRequested event, which displays a tooltip if the text entered into the RadCombobox does not return any items. - I did it client side as i was having difficulties getting it to work by showing it from the code behind.

The majority of cases this is fine, but i've experienced it sometimes showing before any results have been returned from the database.

I have one client who is being quite insistant in telling me that he can type something, gets a tooltip showing 'No results for <his search>' when there are actually results for his search, they just haven't been returned from the database yet.

Can someone suggest how I can prevent this happening, and only show the Tooltip if no results are returned.

Here is the code for my 'checkFound' function incase you need it.

function checkFound(sender, args) {

var count = sender.get_items().get_count()

if (count <= 0 && sender.get_text().length > 0) {

var tt = $find('<%=tt_searchArea_empty.ClientID %>');

tt.set_text("No results found for '" + sender.get_text() + "'");

tt.show();

}

else {

hideAreaEmptyToolTip();

}

function hideAreaEmptyToolTip() {

var tt = $find('<%=tt_searchArea_empty.ClientID %>');

tt.hide();

}

RadSchedular Incorrect behaviour with different DOCTYPE in IE

Hi ,

I use the RadSchedular in which i use the AdvancedEditTemplate this Schedular is inside an RadPanelBar and when i edit the appointment the edit window gets opened within the RadPanelBar . I want it to cover up the whole screen instead just the panel .

I have also found that this works fine in FireFox and does not work in IE .

I have also found that to make it work in IE (IE 9) i had to change the DOCTYPE attribute to

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
but the project im working on uses the one below and changing it to the above one will require a lot of changes to the Project.
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN" >

Also find the attached images in order to reproduce the error .
The doc.png shows the DOCTYPE being used .
The ie9opensinsidethepanelbar.png and firefox.png shows the output in the IE 9 and Firefox when using the DOCTYPE
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN" >

Thanks & Regards,
Francis P.

NeedDataSource called before ItemCommand

Sir ,

I am new for telerik. Am using the hierarchical radgrid. But causing error when enableviewstate=false.
NeedDataSource called before ItemCommand.So my grid not able to fetch the proper data as its not gets the parentid in NeedDataSource.

If enableviewstate=true my hierarchical radgrid working fine but the parent columns header goes disappers.

Am creating radgrid columns dynamically.

The main thing is that am not getting my parent ticket it first as NeedDatasource calling first than itemdatacommand.

Events are like this.

initializParentGrid()

protected void radrid_NeedDataSource(object source, GridNeedDataSourceEventArgs e)
{
;;;;;;;;;;;;
bindGrid();
}

protected void radrid
_ItemCommand(object source, GridCommandEventArgs e)
{

if (e.CommandName == "ExpandCollapse")
{
GridTableView gtv = radrid
.MasterTableView.Items[e.Item.ItemIndex].ChildItem.NestedTableViews[0];
Telerik.Web.UI.DataKey gdka = radrid
.MasterTableView.DataKeyValues[e.Item.ItemIndex];

hdnDetailTableIndex.Value = e.Item.ItemIndex.ToString();

if (gdka != null)
hdnParentTicketid.Value = gdka["ParentId"].ToString();

}

Please suggest.

How ti reselect datagrid row?

Hi,

I have 2 rad grids. First one is master and second one is detail. I can delete rows from both grids independently by pressing "Delete" button on toolbar above each grid. I also have "Refresh" buttons in toolbar of both grids.

The problem is with detail grid. When I delete item(s) the grid doesn't refresh. Calling Rebind method doesn't help. The only thing that helps is to press "Refresh" button in toolbar of master grid and select the row in master grid by mouse that was previously selected. After that I can see refreshed detail grid.

So, I don't need to press "Refresh" button in toolbar of master grid and select the row in master grid by mouse. I can refresh the master grid programmatically and only want to reselect the item that was originally selected also programmatically. I've tried this:

item.Selected = true;

But, it only visually selects the item in master grid and doesn't refresh the detail grid.

So, how to select the item in master grid programmatically in order to get the same effect as selecting it by mouse?

Thank you in advance.

Chart Series Colors not Changing

Hi,

I have two line series.I set the first serie color to BLUE, then I set the second serie color to RED.
I don't know why the second serie always appear BLUE. I think this might be simple but I can't visualize the solution.
Can anyone help? The code Follows below:

private void PopulateChart3(string seriesID)

{

RadChart1.Clear();

SapeDBDataContext db = new SapeDBDataContext();

int ID = Convert.ToInt32(seriesID);

var windh = from p in db.SAPE_WindSeries where p.id_localidade == ID where p.valorh != null select p;

var windp = from p in db.SAPE_WindSeries where p.id_localidade == ID where p.valorp != null select p;

ChartSeries s = new ChartSeries();

s.Type = Telerik.Charting.ChartSeriesType.Line;

s.Appearance.LabelAppearance.Visible = false;

s.Name = "Historic";

s.Appearance.LineSeriesAppearance.Color = System.Drawing.Color.Blue;

foreach (var wi in windh)

{

ChartSeriesItem item = new ChartSeriesItem();

item.XValue = Convert.ToInt32(wi.dia);

item.YValue = Convert.ToDouble(wi.valorh);

s.Items.Add(item);

}

ChartSeries s2 = new ChartSeries();

s2.Type = Telerik.Charting.ChartSeriesType.Line;

s2.Appearance.LabelAppearance.Visible = false;

s2.Appearance.LineSeriesAppearance.Color = System.Drawing.Color.Red;

s2.Name = "Projected";

foreach (var wi in windp)

{

ChartSeriesItem item2 = new ChartSeriesItem();

item2.XValue = Convert.ToInt32(wi.dia);

item2.YValue = Convert.ToDouble(wi.valorp);

s.Items.Add(item2);

}

RadChart1.Series.Add(s);

RadChart1.Series.Add(s2);

}

Thanks,

PoliklinlList.aspx
Tanilar.ascx

Ajax manager is in the Poliklinik page.
There are two radgrid in web user controls: radTanilar and radSeciliTanilar
I want to add some value from radTanilar to radSeciliTanilar after adding I want to show it in the page.But radSeciliTanilar isn't refresh itself although my web user control is in the updatecontrol of ajax settings.

.

I manage to call my ajax manager from web user control like:

function TanilarRowClick(sender, eventArgs) {

var id = eventArgs.getDataKeyValue("ID");

document.getElementById("grdTanilarDClickedRowIndex").value = id;

$find("<%= RadAjaxManager.GetCurrent(Page).ClientID %>").ajaxRequest("taniekle");

}

When I click the radTanilar row, TanilarRowClick event run and myRadAjaxManager1_AjaxRequest which is in the PoliklinlList page is run also.

myRadAjaxManager settings like this: (ucpTani is the Id of web user controls')
)

<telerik:RadAjaxManager ID="RadAjaxManager1" OnAjaxRequest="RadAjaxManager1_AjaxRequest"

runat="server">

<AjaxSettings>

<telerik:AjaxSetting AjaxControlID="RadAjaxManager1">

<UpdatedControls>

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

</UpdatedControls>

</telerik:AjaxSetting>

</AjaxSettings>

</telerik:RadAjaxManager>

When I add my controls(radseciliTanilar and radTanilar) which are in web user controls manually on code like this:

RadGrid grdSeciliTanilar = (RadGrid)ucpTani.FindControl("grdSeciliTanilar");
