Hi,

I am using a Radnumerictextbox with this code on front side and I am setting its parameters on the codebehind according to selection,
On aspx:

<telerik:RadNumericTextBox ShowSpinButtons="true" NumberFormat-DecimalDigits="4" IncrementSettings-InterceptArrowKeys="true"

IncrementSettings-InterceptMouseWheel="true" Label="" runat="server" ID="txtPrice"

Width="80px">

</telerik:RadNumericTextBox>

On .cs

txtPrice.MinValue = 1.2575
txtPrice.MaxValue= 1.4575
txtPrice.IncrementSettings.Step =0.0005

The problem is while using spin buttons to change values , it show the decimal part more than i set which was 4.

For instance ; when the value is set to 1.2580 it shows 1.257999999999. After clickling up spin button it makes it 1.2585 and after some more clicking on some other values ist shows this 999999 part of decimal thing.

Is this a bug of the component ? if so, what can i do to fix this.

Postback Issue in custom webpart.

Hello,
I am creating a custom webpart using telerik combobox . And i have used Radajaxmanager to avoid postback on the selectedindexchanged event of the combobox.But when i run the webpart this event works fine but postback happens in the first attempt.But from second attempt onwards ajax works. Please tell me the solution to avoid this postback in the first attempt of change event of combobox.

Please find the below code for your reference.

   protected override void CreateChildControls()
        {
            base.CreateChildControls();
            try
            {
                _panel = new Panel();
                _panel.ID = "panel";

                _tblSearch = new Table();
                _tblSearch.ID = "TblSearchCriteria";
                _tblSearch.CssClass = "ms-formtable";
                _tblSearch.Attributes.Add("border", "0");
                _tblSearch.Attributes.Add("width", "100%");
                _tblSearch.CellPadding = 0;
                _tblSearch.CellSpacing = 0;
                _tblSearch.Style.Add("margin-top", "8");

       _cobSearchCriteria = new RadComboBox();
                _cobSearchCriteria.ID = "cobSearchCriteria";
                _cobSearchCriteria.Width = Unit.Pixel(500);
                _cobSearchCriteria.Skin = "WebBlue";
                _cobSearchCriteria.MarkFirstMatch = false;
                _cobSearchCriteria.AutoPostBack = true;
                _cobSearchCriteria.SelectedIndexChanged += new RadComboBoxSelectedIndexChangedEventHandler(_cobSearchCriteria_SelectedIndexChanged);

       _tblSearch.Controls.Add(_cobSearchCriteria);

       _panel.Controls.Add(_tblSearch);

           am = new RadAjaxManager();
                    am.ID = "RadAjaxManager1";
                    Controls.Add(am);
                    Page.Items.Add(typeof(RadAjaxManager), am);
                    lp = new RadAjaxLoadingPanel();
                    lp.ID = "RadAjaxLoadingPanel1";
                    // lp.IsSticky = true; Check this property for the position of Loading Panel..
                    Controls.Add(lp);
                    lp.Transparency = 50;

                    img = new System.Web.UI.WebControls.Image();
                    img.ID = "Image1";
                    lp.Controls.Add(img);
                    img.AlternateText = "Loading...";
                    img.ImageUrl = RadAjaxLoadingPanel.GetWebResourceUrl(Page, "Telerik.Web.UI.Skins.Default.Ajax.loading.gif");
                    img.Style.Add("border", "0px");

                    am.DefaultLoadingPanelID = lp.ID;

                    // Adding Controls to RadAjax Manager
                    am.AjaxSettings.AddAjaxSetting(_cobPredPrijemce, _panel);
                    // Done Adding Controls to RadAjax Manager

   }

protected void _cobPredPrijemce_SelectedIndexChanged(object o, RadComboBoxSelectedIndexChangedEventArgs e)
        {
            // throw new NotImplementedException();
            //am.AjaxSettings.AddAjaxSetting(_cobPredPrijemce, _panel);
            _tblUpdate.Visible = true;
            _tblFyzická.Visible = false;
            _tblPodnikající.Visible = false;
            _tblOVM.Visible = false;
            _tblPrávnická.Visible = false;
            _tblSearch.Visible = true;

        }

Kindly revert asap. Thanking you in Advance.

Preview Row and Multiple Header in RadGrid

Hi.

Please find the two attached snapshots of WebGrid control from Intersoft WebUI Control Library.
We're migrating from Intersoft to Telerik Library to get the Keyboard support feature requested by customers.
The question is regarding the two features shown from WebUI:
- to show one column as a hidden section (not load-on-demand) to be available on clicking the arrow (as shown in PreviewRow_WebUI.png), and
- to show a grouping of the headers with a TopHeader sitting on top of two SubHeaders in Grid.

Can this behaviour somehow be achieved in Telerik RadGrid?
If it is already supported, please tell me where I can find it or how ti can be done. And if not, customizations are most welcome.

Thanks and Regards,
Veenu Munjal

Radajax panel - JQuery - Menu

Hello,

i've created a vertical menu by showing and hiding divs using JQuery. I have wrapped all the divs in a RadAjax panel. The jquery script is written in Page load to show and hide the divs. After the panel loads the scripts are not fired and all the divs are rendered visible. So what should i do?

Also if i'm in the fourth menu, after the ajax loads the page should show the fourth div hiding all the other divs. How to do that?

Thank You.

Allow only Insert/Delete actions in RADGrid with EditMode="InPlace"

Hi, I'm wondering if there is a way to allow only Insert and Delete actions in a RADGrid when using EditMode="InPlace". I have a GridEditCommandColumn in the grid, but I really only want users to be able to Insert/Delete records in this grid, not add. Any ideas?

Thanks in advance,
Andrew

Common Loading Panel?

Is this at all possible? I want to have a common loading panel, that covers my entire page, and is shown no matter what ajaxcontrolid is issuing the call. I know I can do it by creating an ASP panel around the entire page, but that would also transmit all the data within that panel... which is exactly what I'm trying to avoid. I want to have Control A update Control B, and Control C update Control D, etc. but any of these minor updates need to show a loading panel over the entire page.
