Trouble with numeric text box and validators

I am trying to use an asp range validator to throw a message when the user tries to hit the save button. It works when I do not set a min and max value. I am setting the min and max value in the code behind. Any suggestions?

    
                    <asp:RangeValidator ID="rv" runat="server" ErrorMessage="Enter a valid value." 
        
                        ControlToValidate="txt" Type="Integer" MinimumValue="0" 
        
                        MaximumValue="100"></asp:RangeValidator> 
        
                                        <telerik:RadNumericTextBox ID="txt" runat="server" Culture="en-US" Type="Percent" 
        
                                            Width="90px" InvalidStyle-BorderColor="Red" InvalidStyle-BorderStyle="Solid" 
        
                                            AllowOutOfRangeAutoCorrect="false" InvalidStyle-BorderWidth="2" CausesValidation="true"> 
        
                                            <ClientEvents OnLoad="Load" OnBlur="Blur" OnFocus="Focus" OnError="Error" /> 
        
                                            <NumberFormat DecimalDigits="4" AllowRounding="false" KeepNotRoundedValue="true" /> 
        
                                        </telerik:RadNumericTextBox>

RadTreeView, Templates and Server Side Callback

I am in the process of converting my RadTreeView to use the ASP AJAX RadTreeView and I am having some trouble. I have a NodeTemplate that uses DataBinder.Eval() calls to build the template. On the server, I get a hierarchical datasource and manually add the nodes (not using a databind). This would add the nodes but none of the DataBinder tags were being resolved. I read in your documentation that I needed to call DataBind() on the treeview control. I added that call and the tags are being resolved and the templates are working.

Now the problem is when I try to expand a node that wasn't initially expanded. I am using the ServerSideCallBack mode on the node. The NodeExpanded event will fire and I will manually add the child nodes to the selected/expanded nodes but once again, the template isn't working and the DataBinder.Eval calls are not being made. I have tried calling DataBind on the nodes being added, the node that was expanded and the RadTreeView control itself but to no avail.

Any ideas and help would be appreciated.

[Solved] What is the ID of the 'Options' button in the InlineInsertTemplate?

Hello,

In my FormCreated method in the code behind, I am trying to set the visibility of the 'Options' button in the InlineInsertTemplate to false in the manner below:

if (e.Container.Mode == SchedulerFormMode.Insert)

{

   LinkButton Options = (LinkButton)e.Container.FindControl("InsertMoreButton");

   Options.Visible = false;

}

This code does not work however, as the FindControl method isn't finding the button. I.e, I get the following error: "Object reference not set to an instance of an object."

I only want this to happen for the InlineInsert form, so using the RadScheduler property below:

EnableAdvancedForm="false"

... is no good for me as this affects the Options button for both the InlineEdit and InlineInsert templates.

Note: I am trying to avoid creating my own template, as the built-in styling over-complicates what I need to do in the time that I have.

I look forward to your response.

scrollintoview with ajaxified control doesn't work

Hello,

I am using radtreeview on page with RadAjaxManager for ajaxifying controls
Radtreeview is used to update other controls, as well as to be updated from another control, via radajaxmanager

Also have onClientLoad event on radtreeview and associated script:

<script type="text/javascript" language="javascript">

function ScrollToSelectedNode() {

var tree = $find('<%=tv_Projects.ClientID %>');

var selectedNode = tree.get_selectedNode();

if (selectedNode) {

selectedNode.scrollIntoView();

}

</script>

<telerik:RadSplitter runat="server" ID="rdSplitter" LiveResize="False" Width="100%"

Height="550px" VisibleDuringInit="False">

<telerik:RadPane ID="radPaneTreeviews" runat="server" MinWidth="50" Width="250px">

<telerik:RadTreeView ID="tv_Projects" Runat="server" CheckBoxes="False" s Height="100%"

DataFieldParentID="ParentID" DataFieldID="ProjectID" DataTextField="NodeText"

DataValueField="NodeText" OnClientLoad="ScrollToSelectedNode" OnClientNodeExpanded="ScrollToSelectedNode">

</telerik:RadTreeView>

</telerik:RadPane>

<telerik:RadSplitBar ID="rdSplitBar" runat="server" CollapseMode="Forward">

</telerik:RadSplitBar>

<telerik:RadPane ID="radPaneGrid" runat="server" Width="100%" MinHeight="550"

MinWidth="50" Scrolling="Y">

<asp:Panel ID="MainContentPanel" runat="server" Style="text-align:right">

</asp:Panel>

</telerik:RadPane>

</telerik:RadSplitter>

However, selectedNode.scrollIntoView(); , although executed (verified!), doesn't produce any effect.

If ajaxifying and RadaAjaxManger is not used, but only regular postbacks, everything works fine.

What has to be changed, in order to get radtreeview scrolled to selected node, with ajax switched on?

Thanks,
Marijana

Hierarchy with Templates

Hi,

I'm trying the use the http://demos.telerik.com/aspnet-ajax/grid/examples/hierarchy/nestedviewtemplate/defaultcs.aspx as a start up for my scenario. I would like to have the Grid in the Sales tab (only down to customer level, no order details) the ability to add and delete. I'm having a problem trying to read the value of the Label1 when click on update. So saying, if I want to add customer an employee, how can that be done.

thanks

Pager Position=TopAndBottom weird behaviour

Hello,

I'm using a RadGrid with a Pager whose custom values are added in the ItemDataBound item by:

protected void RG_Results_ItemDataBound(object sender, GridItemEventArgs e)

{

if (e.Item is GridPagerItem)

{

RadComboBox pagerCombo = e.Item.FindControl("PageSizeComboBox") as RadComboBox;

pagerCombo.Items.Clear();

RadComboBoxItem item = new RadComboBoxItem("10", "10");

item.Attributes.Add("ownerTableViewId", RG_Results.MasterTableView.ClientID);

pagerCombo.Items.Add(item);

item = new RadComboBoxItem("20", "20");

item.Attributes.Add("ownerTableViewId", RG_Results.MasterTableView.ClientID);

pagerCombo.Items.Add(item);

item = new RadComboBoxItem("50", "50");

item.Attributes.Add("ownerTableViewId", RG_Results.MasterTableView.ClientID);

pagerCombo.Items.Add(item);

item = new RadComboBoxItem("100", "100");

item.Attributes.Add("ownerTableViewId", RG_Results.MasterTableView.ClientID);

pagerCombo.Items.Add(item);

item = new RadComboBoxItem("200", "200");

item.Attributes.Add("ownerTableViewId", RG_Results.MasterTableView.ClientID);

pagerCombo.Items.Add(item);

pagerCombo.FindItemByText(e.Item.OwnerTableView.PageSize.ToString()).Selected = true;

}

The top pager works fine.

But the bottom pager has a weird behavior:

On first click on the down arrow, it only shows the first value ("10" in my code sample).

I have to click twice to get all the values

(Show attachment for screenshot)

Does anyone have an idea on how to fix this ?

Thanks a lot for your response
