How to show the Pop Up Window Asynchronously

I am trying to open the Pop Up window Asynchronously. Due to lengthy Database operation. I am waiting to open the Pop up for approximately 35 seconds...The Problem gets worst when the internet speed is very slow. In that case a lot of time. I am using the below mentioned code...

<telerik:RadWindowManager

ID

="RadWindowManager1"



        ShowContentDuringLoad

="false"
VisibleStatusbar=

"false"

runat="server" 

        VisibleOnPageLoad="false" 

        Width="894px" 

        Modal="true" 

        Behaviors="None"

EnableEmbeddedSkins="false" 

        EnableShadow="true" 

        OnClientClose="OnClientClose"

ReloadOnShow="false">

<Windows

<telerik:RadWindow ID="radPopup" runat="server" KeepInScreenBounds="true" EnableShadow="true"

/>

</Windows

</telerik:RadWindowManager>

My Query is, What should I do to open the Pop Up first and in the Background the Database Operation is being executed...and during this operation the user may be informed about the busy operation...

GridTemplateColumn Hiding

Hello,

Quite accidentally, I've found an interesting behavior with the RadGrid's GridTemplateColumn:

<telerik:RadGrid runat="server" ID="radgrid" AutoGenerateColumns="false" OnNeedDataSource="radgrid_NeedDataSource">

<MasterTableView>

<Columns>

<telerik:GridTemplateColumn DataField="Text" HeaderText="foo">

<ItemTemplate>

<%# Eval("Text") %>

</ItemTemplate>

</telerik:GridTemplateColumn>

<telerik:GridBoundColumn DataField="Text" HeaderText="bar" Visible="false" />

<telerik:GridEditCommandColumn HeaderText="Edit" />

</Columns>

</MasterTableView>

</telerik:RadGrid>

In normal mode, the GridTemplateColumn will be visible, but when in edit mode, it's the GridBoundColumn that's visible. You can tell by the HeaderText that's displayed in the edit form.

Out of curiosity, is this an intended behavior?

Showing only dates with values (autostep?)

Hello Telerik Community:

I have the following issue, using the following code I get the results shown in the attached image.

Is there anyway to autostep or show only the dates that have some value on them?

Thanks in advance!

//OADate column for chart:

DataColumn col = new DataColumn("OADate", typeof(System.Double));

dtable.Columns.Add(col);

//Converting SQL Datetime values to OADate column

int b = 0;

foreach (DataRow row in dtMerArrCru.Rows)

{

row["OADate"] = Convert.ToDateTime(dtable.Rows[b][1]).ToOADate();

b++;

}

//Formatting chart:

RadChart1.PlotArea.XAxis.Appearance.ValueFormat = Telerik.Charting.Styles.ChartValueFormat.ShortDate;

RadChart1.PlotArea.XAxis.Appearance.CustomFormat = "MM/dd/yyyy";

RadChart1.PlotArea.XAxis.IsZeroBased = false;

RadChart1.PlotArea.XAxis.AutoScale = false;

RadChart1.PlotArea.XAxis.AddRange(Convert.ToDouble(dtMerArrCru.Rows[0]["OADate"]), Convert.ToDouble(dtMerArrCru.Rows[dtMerArrCru.Rows.Count - 1]["OADate"]), 1);

RadChart1.DataGroupColumn = "Type";

RadChart1.DataManager.ValuesXColumn = "OADate";

RadChart1.DataManager.ValuesYColumns = new string[] { "Quantity" };

RadChart1.DataSource = dtable;

RadChart1.DataBind();

Unwanted Resize

I'm using the ItemTemplate. In the template I have one user control which consists of a button and another control. The button controls the visibility of the other control. Not every instance of this user control is the same size. When the controls are initially hidden, clicking the buttons will reveal their respective controls as desired. However, when any of the controls are not initially hidden, the list view sizes all it's items to the potentially largest control whether or not that control is hidden. Any ideas why this would be occuring and how I can work around it? Thanks.

Because of designtime datasource setup, I don't know how to set the default value to the combo using valuefield.

Help me here.

Export - TemplateColumn

Hi.

I am currently facing a problem with the export functionality of the RadGrid.
In my code i am automatically generating templatecolumns with controls inside (RadTextBox, RadCheckBox, RadComboBox and so on)

On my commanditemtemplate i have 4 buttons to export to PDF, XLS, DOC, CSV.
Everything works as expected in XLS (Format = ExcelML) but it fails on the other.

Problems i am facing are:
1.) PDF, DOC, CSV display a client selection column
2.) PDF, DOC, CSV dont display values from RadTextBox and RadNumericTextBox controls
3.) CSV doesnt display values from RadCheckBox controls

When i change my code to generate ASP TextBoxes (one line of code nothing more changed)...
1.) CSV still doesnt display values but PDF, DOC does
2.) PDF overlaps with client selection box (because width of column is 10 and the word "FALSE" is lager so it overlaps with following column), DOC looks fine

And a question how is it possible to export a grid in any given width to PDF?
XLS, DOC, CSV dont give a **** about the width of the grid but PDF seems to care and the grid overflows on the pagewidth end, and maybe on the pageheight aswell just dont have enough data to get 2 A4s right now

Hope you can help like to be able to export those 4 formats and have the same data result, styling can and will vary by format but atleast the data should be the same.

Btw, the grid on the page works fine - everything is displayed a expected.
