Export to Excel

I'm exporting a radgrid to Excel successfully. This is my code

gvwMaterial.ExportSettings.ExportOnlyData = true;

gvwMaterial.ExportSettings.IgnorePaging = true;

gvwMaterial.ExportSettings.OpenInNewWindow = true;

gvwMaterial.ExportSettings.Excel.Format = GridExcelExportFormat.Html;

gvwMaterial.ExportSettings.FileName = String.Format("File_{0}_{1}_in_{2}.xls", aaa, bbb.ToString(), ccc.ToString());

gvwMaterial.MasterTableView.ExportToExcel();

When Excel is opened, numbers with decimals, (percents like 0.12), are rounded to 0 or 1
How I can to format this columns?

Thanks

Carlos

Filters in RadGrid not working when page loads for first time

Hi! I have a RadGrid which uses the FilterTemplate with a RadComboBox in GridBoundColumns. When the page initially loads all of the filter options in the RadComboBox are not listed, however, if the page is refreshed all the options appear in the filter.

Currently the SQL statement used to initially populate the filter is in the Page_Load method, and is outside of the 'IF Not IsPostBack' logic.

A method to refresh the combo boxes gets called in the RadGrid1_PreRender event handler. This method takes the original SQL statement and appends a where clause which contains the value selected in the combo box by the user, after which a call to RadGrid1.MasterTableView.Rebind() is made. The actual filtering does work as expected.

I was wondering if someone could provide some insight on how the filtering works in regards to a page initially loading, and if there is a better place to put the logic.

Thanks!

[Solved] List Box not scrolling with page elements

I'm using the basic features of the list box (Q2 2009) and the functionality seems to work fine. I am having an issue with how it handles page resizing and div scrolling.
1. when I resize the browser window (IE 7) - the list box does not move and it overlaps the div border, causing it to cover the footer content.
2. when I scroll the div - all other controls move up or down, but the list box stays put.

I have it sitting in a <div> that has overflow set to auto and it's height set dynamically. The same div contains several Labels.

The short and sweet version of the aspx...

    
            <div id="MainDiv">   
        
            <telerik:RadAjaxPanel> 
        
            <div id="MultipageDiv">   -- this div is set to overflow:auto in a stylesheet;   
        
            <telerik:RadMultiPage> 
        
            <telerik:RadPageView ID="RadPageViewCustomers" runat="server">   
        
            <div id="ViewPageDiv" >              
        
            <asp:Table ID="Table1" runat="server" Width="800px">   
        
            <asp:TableRow> 
        
            <asp:TableCell>   
        
            <telerik:RadListBox>

Any ideas?

Loosing data on postback

I have gridview that i programatically bind to a data-table. one of my column is an hyperlink column that is manually set to show the text "Update" on each row.
I created the following code in the page load event to disable the hyperlink for the appropriate columns:

'Carry out steps to figure if a each report is invoiced or not.

'If invoiced, the update hyperlink is disabled

Dim number_of_reports As Integer = RadGrid1.Items.Count

For i = 0 To number_of_reports - 1

If RadGrid1.Items(i)("status_column").Text = "Not Invoice" Then

RadGrid1.Items(i)(

"update_column").Enabled = False

RadGrid1.Items(i)(

"update_column").Text = "No"

End If

At the page load event the code is handled well. But when i change pages, a postback occurs and the hyperlinks are all reset to the text "update".

I tried putting the code in the radgrid1.page_index_change event but it still does not work.

Setting up Chart Type at runtime in Code Behind

Hi,

I am using RadChart as user control and need to use the control to load different Chart Types.I am able to load the Chart Types but unable to display them as loaded.

<telerik:RadChart ID="rcTrendGraph" runat="server"></telerik:RadChart>

this is my aspx page and in the code behind I am using the following code to Build the Graph.

for (int i = 0; i < strContentIds.Length; i++){

strDashContId = strContentIds[i].ToString();

if (strDashContId == "TGI1002"){

//Bar Graph

rcTrendGraph.ChartTitle.TextBlock.Text = "Bar Graph";

rcTrendGraph.ChartTitle.Appearance.Position.AlignedPosition=Telerik.Charting.Styles.AlignedPositions.Top;

rcTrendGraph.AddChartSeries(legend);

legend.Type = Telerik.Charting.ChartSeriesType.Bar;

rcTrendGraph.DataSource =ds;

rcTrendGraph.DataBind();

}

else if (strDashContId == "TGI1003"){

//Pie Graph

rcTrendGraph.ChartTitle.TextBlock.Text = "Pie Graph";

rcTrendGraph.ChartTitle.Appearance.Position.AlignedPosition=Telerik.Charting.Styles.AlignedPositions.Top;

rcTrendGraph.AddChartSeries(legend);

legend.Type = Telerik.Charting.ChartSeriesType.Pie;

legend.AddItem(10,"A");

legend.AddItem(20,"B");

legend.AddItem(30,"C");

legend.AddItem(40,"D");

}

else if (strDashContId == "TGI1001")

{//Line Graph

rcTrendGraph.ChartTitle.TextBlock.Text = "Line Graph";

rcTrendGraph.ChartTitle.Appearance.Position.AlignedPosition=Telerik.Charting.Styles.AlignedPositions.Top;

rcTrendGraph.AddChartSeries(legend);

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

legend.AddItem(10,"A");

legend.AddItem(20,"B");

legend.AddItem(30,"C");

legend.AddItem(40,"D");

}

I am able to get the chart generated but getting the same chart type at the end..
For Suppose strContentIds.Length=2
and for i=0 strDashContId =TGI1001
and for i=1 strDashContId =TGI1003
I need the chart as pie Graph and Line Graph to be displayed in my page.But I am able to dispaly only one of the chart type i.e, for strDashContId =TGI1003 and strDashContId =TGI1001 I am getting Pie as strContentIds[1]=TGI1003 after strDashContId =TGI1001 and getting both the charts as Pie Charts only.

Please help me out with your suggestions.

Thanks In Advance,
h@r!

Can't get any events to work (client or server)

Sorry if I've missed something obvious, but this seems like it should be very simple. I just want to have an image button that executes some javascript when I click it.

function FBLogin(sender, args) {

FB.login(fb_loggedin, { perms: 'email,publish_stream,offline_access' });

}

<telerik:RadButton ID="RadButton1" runat="server" Text="Login" Height="55px" Width="225px" AutoPostBack="false" OnClientClicked="FBLogin">

<Image ImageUrl="~/Images/fb_btn.png" />

</telerik:RadButton>

Absolutely nothing happens when I click the button. If I make the image a "background" image and add some text then it works, but only if I click on the text. As you can see the button is quite large and the user should be able to click anywhere on the button, not just on the text. Also, I really don't want text (the image already has the text on it).
