[Solved] NumericTextBoxSetting: problem with decimal values + culture

I have a problem with the RadInputManager control. I use a NumericTextBoxSetting control to assure that the user can only enter a decimal value in a text box.

<telerik:RadInputManager ID="imState" runat="server">

<telerik:NumericTextBoxSetting Type="Number" MinValue="0" DecimalDigits="2">

<TargetControls>

<telerik:TargetInput ControlID="tbLength" />

</TargetControls>

</telerik:NumericTextBoxSetting>

</telerik:RadInputManager>

On the same page there's a drop down list which forces the page to carry out a postback. If the culture is for example 'de' and the user enters a double value after a postback this value becomes an integer.
for example: 4,25 -> 425

If the culture is 'en' there's no problem.

Thanks,
Gerhard

[Solved] TreeView value property

Hi,

I am facing issues while binding the XML data to a RADTreeview.

If I use the declarative datasource and bind it to the TreeView it works, but when I specify the datasource from the codebehind, it is not able to set the Node.Value property.

Below code is working:
ASPX Code:

<telerik:RadTreeView ID="rtvCategories" runat="server" DataSourceID="XmlDataSourceCategories" SingleExpandPath="true" onnodeclick="rtvCategories_NodeClick" >

<telerik:RadTreeNodeBinding DataMember="Node" TextField="Text" ValueField="ID" Expanded="false" />

</DataBindings>

</telerik:RadTreeView>

<asp:XmlDataSource runat="server" ID="XmlDataSourceCategories" DataFile="~/v1.xml" XPath="/Tree/Node" />

XML

<?xml version="1.0" encoding="utf-8" ?>

- 

- <Tree>

- <Node ID="3" Text="my category12">

<Node ID="14" Text="disprine" />

</Node>

- <Node ID="3" Text="my category12">

<Node ID="25" Text="Testitem" />

</Node>

- <Node ID="3" Text="my category12">

<Node ID="25" Text="Testitem" />

</Node>

- <Node ID="3" Text="my category12">

<Node ID="25" Text="Testitem" />

</Node>

- <Node ID="3" Text="my category12">

<Node ID="35" Text="my Item" />

</Node>

- <Node ID="3" Text="my category12">

<Node ID="35" Text="my Item" />

</Node>

- <Node ID="4" Text="Animal Category">

<Node ID="25" Text="Testitem" />

</Node>

</Tree>

Code not working (the data is getting displayed but Node Value always returns blank):

<telerik:RadTreeView ID="rtvCategories" runat="server" SingleExpandPath="true" onnodeclick="rtvCategories_NodeClick" >

<DataBindings>

<telerik:RadTreeNodeBinding DataMember="Node" TextField="Text" ValueField="ID" Expanded="false" />

</DataBindings>

</telerik:RadTreeView>

protected void Page_Load(object sender, EventArgs e)

{

   string xmlData = "";

   // Below method

getXMLCategoryItemList

returns the same xml as string

   xmlData = objFH.getXMLCategoryItemList().ToString();

   rtvCategories.LoadXmlString(xmlData);

   rtvCategories.DataBind();

}

protected void rtvCategories_NodeClick(object sender, Telerik.Web.UI.RadTreeNodeEventArgs e)

{

lblResult.Text = e.Node.Value.ToString();

}

Kindly help me in resolving the issue.

Thanks

custom markpoints

Hi, I am have a point chart, and i want each point on the graph to be different,
So for example i have the following table of data

Scroll to Item

Hello,
i use a RadGrid in a UpdatePanel. The cells contain ImageButtons.

<asp:UpdatePanel ID="UpdatePanel1" runat="server">

<ContentTemplate>

<telerik:RadGrid ID="RadGrid1" runat="server" Width="900px" Height="400px"

<MasterTableView TableLayout="Auto" />

</telerik:RadGrid>

</ContentTemplate>

<Triggers>

<asp:AsyncPostBackTrigger ControlID="RadGrid1" EventName="ItemCommand" />

</Triggers>

</asp:UpdatePanel>

Code:

protected void RadGrid1_ItemDataBound(object sender, Telerik.Web.UI.GridItemEventArgs e)

{

if (e.Item is GridDataItem)

{

GridDataItem item = (GridDataItem)e.Item;

Label lbl = new Label();

lbl.Text = item[""].Text.Substring(item[""].Text.IndexOf("|") + 1);

item[""].Controls.Add(lbl);

for (int i = 0; i < gruppenliste.Count; i++)

{

ImageButton imgbtn = new ImageButton();

if (item[gruppenliste[i].ToString()].Text.StartsWith("0"))

{

imgbtn.CommandName = "add";

imgbtn.ImageUrl = "../img/cancel.gif";

item[gruppenliste[i].ToString()].Controls.Add(imgbtn);

item[gruppenliste[i].ToString()].HorizontalAlign = HorizontalAlign.Center;

imgbtn.CommandArgument = item[""].Text.Substring(

0, item[""].Text.IndexOf("|")) +

"|" +

item[gruppenliste[i].ToString()].Text.Substring(

item[gruppenliste[i].ToString()].Text.IndexOf("|") + 1);

}

else

{

imgbtn.CommandName = "del";

imgbtn.ImageUrl = "../img/ok.gif";

item[gruppenliste[i].ToString()].Controls.Add(imgbtn);

item[gruppenliste[i].ToString()].HorizontalAlign = HorizontalAlign.Center;

imgbtn.CommandArgument = item[""].Text.Substring(

0, item[""].Text.IndexOf("|")) +

"|" +

item[gruppenliste[i].ToString()].Text.Substring(

item[gruppenliste[i].ToString()].Text.IndexOf("|") + 1);

}

When I click a ImageButton, then the grid in the UpdatePanel is refreshed.
How can I automatically scroll back to the current row/column (ImageButton) after the refresh?
