Is there a way to set the DPI settings for the chart image. I did notice an internal property for BitmapResolution;however I did not see anyway thru the control to set that.

While I could use the code below to save a 300dpi image of the chart, isn't the source images (the generated chart) dpi set to the chart defaults?

System.Drawing.Bitmap image = RadChart1.GetBitmap() as System.Drawing.Bitmap;

image.SetResolution(300, 300);

image.Save(@"C:\myimage.png");

I would not want to take at 96dpi image and convert it into a 300dpi image, where are those extra dpi's gonna come from? I think of that like taking a 200px X 200px image and resizing to 400px X 400px, which would not produce the same quality image I would get pixelation.

I have created a Chart generator control where the user can enter data etc.. and generate the chart from the data. Then I want to allow them to save the generated chart image at a minimum of 300dpi since this will be added to a print ready pdf. I would want a high quality image produced since this is for printing.

I appreciate any information or advice on this matter.

Thank you!

LoadingPanel and jquery SlideUp

Afternoon everyone, I have a strange issue, when I use the jquery slidup function on a div that contains my 'search' fields and the grid in its own div, everything works fine except the loading panel. it creates its loading panel in side the grid as it should but when search fields div 'slides up' the rest of the html moves up as it should, except the loading panel...

here is some pseudo mark up to explain what i am talking about...

<script>

function hideSearchFields(){

$("#searchDiv").slideUp('medium');

}

</script>

<telerik:RadAjaxManager ID="radAjaxManager" runat="server">

<%--<ClientEvents OnResponseEnd="RadAjaxManagerResponseEnd" />--%>

<AjaxSettings>

<telerik:AjaxSetting AjaxControlID="SearchLinkButton">

<UpdatedControls>

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

</UpdatedControls>

</AjaxSettings>

</telerik:RadAjaxManager>

</telerik:AjaxSetting>

<div id="searchDiv">

labels textboxes drop downs etc....

<asp:linkbutton id="SearchLinkButton" runat="server" OnClientClick="hideSearchFields();" OnClick="search" />

</div>

<div>

<telerik:radgrid id="ResultsRadGrid runat="server">

my grid

</telerik:radgrid>

</div>

<div>

a bunch more html

</div>

<telerik:RadAjaxLoadingPanel ID="RadAjaxLoadingPanel1" runat="server" Skin="Simple">

Scriptmanager error while using RenderControl

Hi,

I have a asp .net page which has RadGrid inside the page. My objective is: on click of a button on the page, i need to get the rendered html of the radgrid so that i can do more processing (for printing/taking screenshots of the grid alone).

Grid:

<telerik:RadGrid ID="grid1" ShowFooter="true"

OnNeedDataSource="grid1_NeedDataSource" ShowStatusBar="true" runat="server" OnItemDataBound="GridCollateralDataBound"

AllowFilteringByColumn="false">

<ClientSettings AllowColumnsReorder="true" ReorderColumnsOnClient="true" AllowColumnHide="true" ColumnsReorderMethod="Reorder">

<Scrolling AllowScroll="true" SaveScrollPosition="true" UseStaticHeaders="false" />

</ClientSettings>

<Columns>

 

                      .......

</Columns>

</telerik:RadGrid>

I have the button which tries to get the render html for this page but it unfortunately fails.

void ButtonClick(object sender, EventArgs e)

{

System.IO.StringWriter stringWriter = new System.IO.StringWriter();

HtmlTextWriter htmlWriter = new HtmlTextWriter(stringWriter);

grid1.RenderControl(htmlWriter);

if (stringWriter != null)

stringWriter.Dispose();

if (htmlWriter != null)

htmlWriter.Dispose();

Here "grid1.RenderControl" code throws error that "Script control 'rghcMenu' is not a registered script control. Script controls must be registered using RegisterScriptControl() before calling RegisterScriptDescriptors().
Parameter name: scriptControl".

I tried setting grid1's RegisterWithScriptManager to false before calling rendercontrol and also tried adding the scriptmanager explicitly for grid1 (added a panel with scriptmanager at run-time and and then grid1 inside). All these options still were still throwing the same error.

Your help on this is appreciated.

Note: I am using the latest version of telerik radgrid: 2011.2.915.40

Regards,
Kishan G K

grid export to pdf, records per page

This is fairly easy to accomplish using the <?hard-pagebreak?>.

Protected Sub RadGrid1_ItemCreated(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridItemEventArgs) Handles RadGrid1.ItemCreated

If e.Item.ItemIndex Mod 7 = 0 AndAlso e.Item.ItemIndex > 1 AndAlso TypeOf e.Item Is GridDataItem Then

e.Item.Attributes.Add("pageBreak", "pageBreak")

End If

End Sub

This inserts a pageBreak="pageBreak" on the 8th <tr>...ie.. <tr pageBreak="pageBreak">

Then using pdfExporting you replace pagebreak="pagebreak" with closing the table, the hard pagebreak, opening the new table. It's hard to get the tags correct because I could not find any documentation about how this xhtml is fabricated, however I was able to save the raw xhtml to file and review it to get the replace correct and fix errors.

Protected Sub RadGrid1_PdfExporting(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridPdfExportingArgs) Handles RadGrid1.PdfExporting

Dim replacement As String = "</tbody></table><?hard-pagebreak?>" & _

"<table >" & _

"<colgroup>" & _

"<col />" & _

"</colgroup>" & _

"<thead>" & _

"<tr>" & _

"<th scope='col' > </th><th scope='col' >Print Column</th>" & _

"</tr>" & _

"</thead>" & _

"<tbody>" & _

"<tr "

e.RawHTML = e.RawHTML.Replace("<tr pageBreak=""pageBreak"""

, replacement)

Dim FILE_NAME As String = "c:\inetpub\PDFServer\file.html"

If System.IO.File.Exists(FILE_NAME) = True Then

Dim objWriter As New System.IO.StreamWriter(FILE_NAME)

objWriter.Write(e.RawHTML)

objWriter.Close()

End If

End Sub

This is a really great feature of radgrid as it makes fabricating these pdfs about as easy as writing html. I just wish there was more documentation on how to do this because it took me forever to find this information. I hope someone else can use these examples to speed up their development.

Multiline style

Can you guys please give me a .riMulti on the root when the textbox is in multi-line mode please? I need to style the multi differently than the normal textboxes

(in the .skin file)

So I know I can add a cssclass to the TBs in multline mode, but that means my developers will have to remember to do that, and they never will...but if I define it in the skin file, whenever they go into multiline mode it'll just be styled properly.

So my problem is the style I need to change is on the wrapper span, I know the regular is an input while multi is a textarea...

Third level hierarchical grid insert to detail table problem

Hi,

I have a third level hierarchical grid.I try to insert/update/delete operations in this grid.I have tried the approach given in this demo,but the problem is I can't insert or update in my second detail table.I can't add or update the data in RecipeIngredients Table.By the way,I am using Sql data source.
My question is how I can insert and update operations in my second detail table?

The database structure of hierarchy is shown below:

RecipeTypes(Master Table) Recipes(Details Table) RecipeIngredients(Details Table)
-RecipeTypeID(PK,int) -RecipeID(PK,int) -RecipeID(PK,FK,int)
-RecipeType(nvarchar) -RecipeTypeID(FK,int) -IngredientID(PK,FK,int)
-RecipeName (nvarchar) -IngredientName(FK,nvarchar)

Ingredients
-IngredientID(PK,int)
-IngredientName(PK,nvarchar)

Cancel Edit - Row Child Control Events Still Fire?

This behaviour is probably by design - but I'm confused as to why I still get the child control value changed events when I hit the Cancel link - I'd have thought they would have been discarded?

So for example - I have a RadGrid with an EditCommandColumn, and a template column with a label in the ItemTemplate, and a TextBox in the EditItemTemplate.

This TextBox has a _TextChanged event which is wired up to change the column in the dataset the RadGrid is bound to.

When I hit Edit, the row goes into Edit mode, and the textbox appears. I then change the text in that textbox, but hit Cancel, rather than Update. The _TextChanged event fires first, before the RadGrid_CancelCommand - so I can't event set a bIsCancelling flag, and have an "If Not bIsCancelling" around the code in my _TextChanged event, to prevent the dataset updating code from executing.

I'm new to these controls, so I'm probably missing something obvious - I just need to know how Cancels are handled correctly with the RadGrid.

Thanks,

Andrew

AllowCustomText and MarkFirstMatch don't work in IE9

I use 2010.1.519.40 version of Rad Controls for ASP.NET AJAX

My RadComboBox uses markfirstmatch="true and allowcustomtext="true"

Here is code snippet:

<telerik:RadComboBox ID="RadComboBox1" runat="server" AllowCustomText="True" MarkFirstMatch="True"

DataSourceID="LinqDataSource1" DataTextField="Name" DataValueField="Id">

</telerik:RadComboBox>

It does not work in IE9.

Autocomplete does not work at all and when I type custom text into control, on postback previously selected is set and RadComboBox1.Text on server side is set to that item.

Is there any fix/workaround?

Validation Summary in Notification

Hey guys, i wonder if someone would be kind enough to help me get the <asp:ValidationSummary> inside the notification box. Specifically the validation summary when client side validation is done, like the <asp:RequiredFieldValidator> or <asp:CompareValidator>. I have already successfully accomplished this scenario on the server side with the <asp:CustomValidator>... Any help with the client side functionality of this would be great!

Thanks,
