[Solved] Object reference not set to an instance of an object.

ok, this error happens on export to excel from my radgrid. I got everything working fine in it and then they wanted me to put on a looker service with a pop-up panel. Since then it breaks, the export to excel, if I take out the code it works fine, i do not want it exported to excel.
it breaks on the follwoing line which is part of the radgri_ItemCreated
pce.BehaviorID = behaviorID

How can I get around this to export the grid without the control

added peices to grid

<telerik:GridTemplateColumn>

<ItemTemplate>

<asp:Image ID="imgLooker" runat="server" ImageUrl="~/Images/ViewResources.gif" ImageAlign="Middle" BorderStyle="None" />

<asp:PopupControlExtender ID="popInfo" runat="server" PopupControlID="pnlPop" TargetControlID="imgLooker" DynamicContextKey='<% #Eval("intRecId") %>'

DynamicControlID="pnlpop" DynamicServiceMethod="HelloWorld" Position="bottom"></asp:PopupControlExtender>

</ItemTemplate>

</telerik:GridTemplateColumn>

Protected Sub myRadGrid_ItemCreated(sender As Object, e As Telerik.Web.UI.GridItemEventArgs) Handles myRadGrid.ItemCreated

If TypeOf e.Item Is GridCommandItem Then

ScriptManager.GetCurrent(Page).RegisterPostBackControl(e.Item.FindControl("btnExport"))

End If

If TypeOf e.Item Is GridDataItem Then

Dim pce As PopupControlExtender = TryCast(e.Item.FindControl("popInfo"), PopupControlExtender)

Dim behaviorID As String = "pce_" + e.Item.RowIndex.ToString

pce.BehaviorID = behaviorID

Dim img As Image = DirectCast(e.Item.FindControl("imgLooker"), Image)

Dim OnMouseOverScript As String = String.Format("$find('{0}').showPopup();", behaviorID)

Dim OnMouseOutScript As String = String.Format("$find('{0}').hidePopup();", behaviorID)

img.Attributes.Add("onmouseover", OnMouseOverScript)

img.Attributes.Add("onmouseout", OnMouseOutScript)

End If

End Sub

TargetControlID=radDatePicker

Dear all,

I'm trying to setup a radtooltip that will appear (ShowEvent="OnFocus") when the user clicks on a radDatePicker. I've tried to set the TargetControlID to be the radDatePicker's ID, ID + "_wrapper" and also tried ID + "_dateInput_text". Is this even possible? If so how can it be done?

Kind regards
Sidharth

Multiline Appointments in the MonthView

I am experimenting with the Scheduler control that is part of he RadControls for ASP.NET AJAX version 2011.3.1305.35. Our customer has a requirement that the appointments in the month view show on two separate lines. e.g. a time range is on the first line and a name is on the second line. Is it possible to enlarge the appointments inthat particular view?

Thanks in advance.

[Solved] Huge numbers of <br> tags added within and to end of text within RadEditor

We have had several users with this problem, but I am unable to replicate it on my system. Near as I can tell, they edit a page, typing in text, save the page, and what is saved is not only the text they have typed but also many <br> tags both between the text that they've typed and after it. Usually there are 5-21 lines of <br>s between text, but some of them have hundreds of <br>s after the text. This is rendering our tool unusable. We are currently using . We thought initially that they were pasting from Word, but that is not the case. We are trying to track users down and gather further information from them, and I'll report back any clarifying info I receive. Initial reports indicate it may be an IE issue and not a FF issue. Any ideas people may have off the tops of your heads would be helpful.

Thanks!

How can I widen the space for the axis labels?

I have a radchart with names instead of numbers on the y axis. However the names are getting cut off. How can I add more space for them?

I've attached a picture so you can see what I'm talking about.

Row Selected Color changes while navigating between Rows

Hi,
I have a RadGrid which displays 250 rows and 18 Columns.
At present, because of our requirement, we can't allow paging.
The Header background color is Navy Blue and the Row Selected color is Light Blue.
However when I navigate between rows using the Keyboard down arrow, the Row Selected Color changes to the Header
background Color as it nears the viewable bottom area of the Grid and once it changes the color, any other row I select, the row selected color is the Header background Color not the original Light Blue I assigned.
Can you please let me know what might be the Issue?
Thanks
Srinivas

RadBinary image Displays the Orginal Image Size.

Hi

I have a RadAsyncUpload to upload the image. Using another button named "UpLoad" generate the postback to upload the image. Save the image in sql Server database in binary format. Retrieve the binary data from the database and set it to the datavalue property of the RadBinary image control. The radbinary image displays the image in it's original size. I have set the width and height of the radbinary image as 200px but the the image is displayed in its original size.
If i will generate a postback again then the image is set in 200px height and width. Please give the solution for this problem.

protected void Page_Load(object sender, EventArgs e)

{

binaryimage1.Height = Unit.Pixel(200);

binaryimage1.Width = Unit.Pixel(200);

b1.Click += new EventHandler(b1_Click);

}

void b1_Click(object sender, EventArgs e)

{

foreach (Telerik.Web.UI.UploadedFile file in uploader.UploadedFiles)

{

byte[] bytes = new byte[file.ContentLength];

string fname = file.FileName.ToString();

int length = bytes.Length;

file.InputStream.Read(bytes, 0, file.ContentLength);

SqlConnection dbconn = new SqlConnection(strconn);

try

{

string Query = "INSERT INTO RadBinaryImageDemo (ImageData,ImageName) VALUES " + " (@imgdata,@imgname)";

SqlCommand cmd = new SqlCommand(Query, dbconn);

SqlParameter[] param = new SqlParameter[2];

cmd.Parameters.AddWithValue("@imgdata",bytes);

cmd.Parameters.AddWithValue("@imgname", file.FileName);

dbconn.Open();

cmd.ExecuteNonQuery();

DataTable d1 = new DataTable();

string Query1 = "select ImageData from RadBinaryImageDemo where ImageName='" + fname + "'";

SqlDataAdapter sqldadap = new SqlDataAdapter(Query1, dbconn);

sqldadap.Fill(d1);

byte[] imgdata = ((byte[])d1.Rows[0]["ImageData"]);

binaryimage1.DataValue = imgdata;

}

finally

{

dbconn.Close();

}

seting default settings in editor

Hello.
I would like to set some settings in server-side.
So i want to enable bold and italics and font-size 22px and selected font Arial(those settings depend on user preferences)
I don't want to use ContentAreaCssFile(which can actually set the font-weight bold but not make the B button look like it's pressed.Of course i can use js...).
Any ideas?Thanks.
