I have an odd problem on the zooming on Stock Chart, the X Axis becomes corrupt.

When I zoom it sorts itself out.

If just plot the points with a default Layout it is OK unzoomed.

I am doing this for both types:

var xAxis = chart.PlotArea.XAxis;

xAxis.Step = Convert.ToDecimal(xAxis.Items.Count * 0.10);
xAxis.BaseUnitStep = Convert.ToInt32(xAxis.Step);
xAxis.BaseUnit = DateTimeBaseUnit.Minutes;
xAxis.EnableBaseUnitStepAuto = false;

Please see attached images.

[Solved] Click in a radgrid.

Hi,

I need to click on some link in my rad grid.

I have 2 like per row.

on each link im using the following code till i get an answer:

<telerik:GridHyperLinkColumn

UniqueName ="LinkRpt"

DataTextFormatString="S/N {0} "

DataTextField="UsrSN"

DataNavigateUrlFields="CaseID"

DataNavigateUrlFormatString="~/Site/mypage.aspx?var={0}"

HeaderText="Repport link" >

</telerik:GridHyperLinkColumn>

As you can see im using " Request.QueryString["var"] ".
But i want the var to be in Session. Because this 'var' is a sensitive data.

I know how to put things in session. Session["field1"] = "value1";

But i can't do that with a GridHyperLinkColum because there is no OnClick event.
Its the same for the GridButtonColumn.
So i guess i have to use GridTemplateColumn with a RadButtonin it.

<telerik:GridTemplateColumn >

<ItemTemplate>

<telerik:RadButton

ID="RadButton1"

runat="server"

Text="See Repport."

OnClick="RadButton1_Click" >

</telerik:RadButton>

</ItemTemplate>

</telerik:GridTemplateColumn>

In this RadButton1_Click, what should i do to get the CaseID of the row clicked.

How do i navigate to my "~/Site/mypage.aspx" ?
if i use Javascript:

function OnClientClicking(button, args) {

window.location = button.get_navigateUrl();

args.set_cancel(true);

}

with the OnClientClicking how do i set things in session ?

Any suggestion will be appreciated.

Regards,
Pierre.

Default Image for GridImageColumn

I have a RadGrid up and running, and have added GridImageColumn. It works well. However, not all rows have an associated image. How would I setup a default image that would display in those instances?

<telerik:GridImageColumn DataType="System.String" DataImageUrlFields="PartFamily"

DataImageUrlFormatString="images/family-images/{0}.png" AlternateText="Family Image" DataAlternateTextField="PartFamily"

ImageAlign="Middle" ImageHeight="75px" ImageWidth="75px" HeaderText="Image Column"

</telerik:GridImageColumn>

New proerty

Instead of asking for single or multiple entries why not simply have a property called selectamount and enter the amount of selections that can be selected. This way we can restrict selections to the amount we need. Multiple is way to vague and single can be set to 1.

RAD Scheduler ON edit showing recurrence popup

Hi Everybody,

I have downloaded the latest version(2011.2.915.35) trial of telerik.

When i create an event in rad scheduler by default its creating the event as recurring event,
i don't want to create events as recurring event.

For edit its asking "Editing a recurring appointment" with two options "Edit only this occurence" & "Edit the series"

Have attached the screen shot as well.

i don't want this confirmation window.

Anyone please give me suggestions to remove this confirmation window and to change creating appointment as recurring by default.

Thank You

Exporting to xlsx also export GridEditCommandColumn but should not

Until recently I was exporting to Excel using ExcelML format. The GridEditCommandColumn was not exported (ExportOnlyData is set to true).
I am now exporting using XLSX format. Since then, the GridEditCommandColumn is exported along with data.
I would expect the same behaviour (no edit column).

Is it a bug ?
Is there an option to hide GridEditCommandColumn when exporting to xlsx ?

<telerik:RadButton ID="ButtonExportExcelML" runat="server" Text="Export to ExcelML" OnClick="ButtonExportExcelML_Click" />

<telerik:RadButton ID="ButtonExportXLSX" runat="server" Text="Export to XLSX" OnClick="ButtonExportXLSX_Click" />

<telerik:RadGrid ID="RadGrid1" runat="server" AutoGenerateColumns="true" ExportSettings-ExportOnlyData="true" OnNeedDataSource="RadGrid1_NeedDataSource">

<MasterTableView>

<Columns>

<telerik:GridEditCommandColumn ButtonType="ImageButton" />

</Columns>

</MasterTableView>

</telerik:RadGrid>

protected void RadGrid1_NeedDataSource(object sender, Telerik.Web.UI.GridNeedDataSourceEventArgs e)

{

RadGrid1.DataSource = new List<int> { 1,2,3,4,5,6};

}

protected void ButtonExportExcelML_Click(object sender, EventArgs e)

{

RadGrid1.ExportSettings.FileName = "TestExcelML";

RadGrid1.ExportSettings.Excel.Format = GridExcelExportFormat.ExcelML;

RadGrid1.ExportToExcel();

}

protected void ButtonExportXLSX_Click(object sender, EventArgs e)

{

RadGrid1.ExportSettings.FileName = "TestXlsx";

RadGrid1.ExportSettings.Excel.Format = GridExcelExportFormat.Xlsx;

RadGrid1.ExportToExcel();

}

Database Pagination for RadGrid, not Page UI Pagination

Hi,

Does RadGrid has built-in Database Pagination in addition to the standard Grid UI Pagination?

For example:

In RadGrid standard Page UI Pagination, if you have page size of 25, when the data source is bound then the whole dataset (e.g. 500 member records) is retrieved from the database, but only renders the first 25 records. When the user clicks to go to page 2 the query is run to get the 500 records again and the telerik control will then render the next batch of 25 records in order. Does RadGrid has built-in Database Pagination in addition to the standard Grid UI Pagination that can limit the records retrieved from the database to, say 100 records rather than retrieving 500 records?

HeaderContextMenu add/remove items vb.net

I have successfully been able to hide items from the context menu. Is it possible to remove the separator bars that also appear in the menu? Also I am struggling to be able to add my own items. I have seen the examples in c#, however these do not translate well to vb. Below is the code I am using to hide the items. It would be much appreciated if someone could show me how to add new items. Once added I would also need to know how to capture the fired event when the menu item is clicked.
