RadGrid - canceling update due to missing value

Hello.

I can reference the certain control in the template edit form and read it's new value (from within the "OnItemUpdated" event), but I don't know how to cancel the on-going update? On the update button I'am using CommandName="Update" Please advise.

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();

}

Upload and delete buttons are disabled when using custom content provider

Hi,

I have to customise File Explorer to save and read files from a UNC path (eg.\\ComputerName\SharedFolder\Resource) that resides on a shared folder. I am saving the file definitions on database except the content which is being saved on the above path.

I am able to achieve file save functionality with simple c# code. Selecting the file from gridview is reading the file from above path and creating a preview successfully (making use of a generic handler here). However, I can't delete this file, as the delete icon is disabled.

I can make sure that user has got full permissions on this path.

Another issue is that, when the control is loaded for the first time and there is no content in it, all the control buttons i.e upload, delete etc.. are disabled.

Can you please suggest any solution to this issue?

Thanks.

I am using the exact example as shown here -http://docs.telerik.com/devtools/aspnet-ajax/controls/grid/hierarchical-grid-types-and-load-modes/several-tables-at-a-level

I am using SeverOnDemand on Master and DetailTables.

Using below line in RadGrid1_DetailTableDataBind(), all the rows in the masterTable gets expanded on click of the Expand toggle button.

RadGrid1.MasterTableView.HierarchyDefaultExpanded = True
e.DetailTableView.HierarchyDefaultExpanded = True

How to make the row expand or collapse on toggle sever side?

Any help is appreciated. Thanks.

Appointment Description Not Displayed

G'Day,

I am using the RadScheduler (Q3 2009) within moss and all was fine until our client requsted additional information be displayed within the scheduler.

It looks like the information can be displayed by populating the Appointment.Description property with the required text should be the solution, however it does not get displayed on screen. Only the Appointment.Title is shown.

The data is bound to the RadScheduler via a custom Provider, which returns a Generic list of Appointments.

If I interrogate the data being bound to the RadScheduler during the RadScheduler_AppointmentInsert I find that the Description property holds the expected text.

Thanks

Andrew

White gaps at begin and end

Hi,

We're using your radhtmlchart to display subscriptions data by month, and this data is dynamically. Sometimes, there is a huge white gap at beginning and ending of the chart which i can't remove (see the attachment).

For the X axis, i have set the MaxDate and MinDate values with the first and last possible dates and tried to set Step config but it don't works. The MinValue and MaxValue for Y axis works as expected.

Is there something i can try to minimalize this white gaps?

Kind regards,

Jelle

Zooming X Axis Stock Chart

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.

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>
