Hello friends,
I have created a report which uses CSS to set back-ground image a text box. When I run the report using ASP.NET CrystalReportViewer, the CSS formatting was applied but when I tried to print the report, the CSS formatting was not applied.
I am using Crystal Report for Visual Studio .NET 2005.
Please help me in solving this issue.

So, are you getting any error or exception with this code?
I didn't understand your question, can you explain a bit.

Also, no need to use ".ToString()" as ".Text" property returns a string only.
P.S: Put your code in "pre" tags, it'll enhance the readability.

<i displayed values in grid view than in ither tabpanel i hav to display these values in a textbox with concatenation string how i do that plz tell me>

First, tell me whether you want to do this on a particular row selected event or for all rows present in your gridview (Your code is doing this)?

Hi guys.. Im working on a web application on C#.net with VS2003(Framework1.1).. in my page i have a DDL which populates the items from the database... now on my page the user fills a form by selecting the items from the DDL. The user can also edit previous froms, at this stage the datas come from the database and gets filled on the textbox,DDL, radio buttons etc to edit the fields. Now when a data from the database is not present in the DDL list i get an exception to handle this situation i need to set a condition such that it checks if the data from the database is present in the DDL list then it shows in the DDL otherwise it must show the Fist item in the DDL which is "Select an option". so i put up the following condition:
if(ddl_Benef.Items.FindByValue(myDr["BenefName"].ToString().Trim()).Value == myDr["BenefName"].ToString())
{
ddl_Benef.Items.FindByValue(myDr["BenefName"].ToString().Trim()).Selected=true;
}
else
{
ddl_Benef.Items.FindByText("Select an option").Selected=true;
}
here if the data from the database is present in the DDL the code works fine in case the data is not present in the DDL then it doesnt go to the else condition instead gives me "System.NullReferenceException: Object reference not set to an instance of an object."
Any help or advice is appreciated...
Thanx in advance,
Tash

When there is no item in the database, how do you think that it will find the text "Select an option".
Instead of finding the text, you need to add an item like this:
ddl_Benef.Items.Add("Select an option");
Hope this helps!

Hi thanks for ur reply..
actually in my DDL i have set the 1st item as "Select an option" and the remaining items gets populated from the database... now thats not the issue... when i try 2 edit an Existing form, the page loads with the datas from the database at that time it picks up an item from the database and tries to locate that item in my DDL.. what i exactly want is it should not throw an exception if that item is not present in my DDL but instead should display my 1st item which is -- "Select an option"...
Hope u understand rite now..
Thanx in advance..
Tash

You have to do it in your error handling code.

I think im not framing my if condition in a proper manner...
plz advise..
Thanx in advance,
Tash

Debug the code to see if any item exists in the DDL when there is no item received from database. The exception you mentioned tells that you do not have any item in the DDL (not even "Select an Option").

thanx for ur reply..
my DDL gets loaded with the items on pageload. so the DDL has items in it.. the If condition that im using is working fine if the item retrieved from the database is present in my DDL, it throws an exception only if that item is not present in my DDL...
if(ddl_Benef.Items.FindByValue(myDr["BenefName"].ToString().Trim()).Value == myDr["BenefName"].ToString())
{
ddl_Benef.Items.FindByValue(myDr["BenefName"].ToString().Trim()).Selected=true;
}
else
{
ddl_Benef.Items.FindByText("Select an option").Selected=true;
}
Im not sure if my condition in the if statement is properly framed or not...
plz advise..
Thanx in advance,
Tash..

IMO, you should first check whether your condition in if is returning or not.
Try like this:
if(ddl_Benef.Items.FindByValue(myDr["BenefName"].ToString().Trim()) != null)
{
if(ddl_Benef.Items.FindByValue(myDr["BenefName"].ToString().Trim()).Value == myDr["BenefName"].ToString()) { ddl_Benef.Items.FindByValue(myDr["BenefName"].ToString().Trim()).Selected=true; } else
{ ddl_Benef.Items.FindByText("Select an option").Selected=true; }
}
else
{
}
If that value is not null, then proceed. Otherwise, set your default option as selected

I am creating a ASP.Net server control to manage locations. The control is a composite control containing several text-boxes, labels, and a link button. I use the AJAX Control Toolkit to provide a modal popup which contains a Bing map. All the Javascript is in its own file and used as an embedded web resource.
The link button is what opens the modal popup. It also needs to call a Javascript function that initializes the Bing map (onclick = "GetMap();"). There are instances when this server control is placed within an Update Panel (and there is no way to avoid this). When in an Update Panel the link button loses its onclick event. I understand that this is because during an async postback the portion of the DOM that defines the content of the Update Panel is thrown out and reinitialized, resulting in the event breaking. When the control is not in an Update Panel everything works as intended.
I have tried registering events on Page.Load and Page.Init, like so:
link_FindLocation = new LinkButton();
link_FindLocation.OnClientClick = "GetMap();";
Page.Load += delegate(object sender, EventArgs args)
{
link_FindLocation.OnClientClick = "GetMap();";
};
I have also tried flat out writing the function call to the page:
link_FindLocation = new LinkButton();
link_FindLocation.OnClientClick = "GetMap();";
link_FindLocation.Click += delegate(object sender, EventArgs args)
{
Page.Response.Write("<script type = \"text/javascript\">GetMap();</script>");
};
I have put breakpoints on the lines inside each delegate and they do not get hit. I am not aware of any special way to register events of a composite control's child control or the Page.Load/Page.Init events when being done inside a server control. Is there some special way to register these events? (Note: Both those code blocks above are in my CreateChildControls() method)
Below is the GetMap() Javascript function. As you can see it is pretty straight forward.
var map;
function GetMap()
{
if (map != null)
{
map.Dispose();
}
map = new VEMap('map'); map.SetDashboardSize(VEDashboardSize.Tiny);
map.LoadMap(new VELatLong(42.869925, -78.681335), 10);
map.Resize('440px', '360px');
map.SetZoomLevel(12);
}
Does anyone have a solution to Javascript events breaking after an async postback that can be applied to a server control? Everything needs to be done within the server control itself and not in the page that is using the control.

Wouldn't be nice if the modal popup contained code to call
a Javascript function ?

If you are referring to the OnOkScript and OnCancelScript properties of the ModalPopupExtender then I cannot use them. I need the Javascript to run when the ModalPopupExtender 's TargetControl is clicked, not the Ok or Cancel buttons. Also, since the ModalPopupExtender does have to live within Update Panels and still function, both OnOkScript and OnCancelScript (along with several other unrelated things) are inherently broken.
If you are referring to something else, please explain.
Thanks

Actually I was thinking of calling the javascript
from the modal on initiation not by button click.

Hi,
i have a problem retrieving a control that has been added at runtime into the place holder... Please provide help...
<telerik:GridTemplateColumn HeaderText="Description" SortExpression="ProductName" UniqueName="ProductName2">
<HeaderStyle HorizontalAlign="center" />
<ItemStyle HorizontalAlign="Left" Width="700px" />
<ItemTemplate>
<table style="border:0px;" >
<tr >
<td style="border:0px;">
<asp:Label id = "lblProductDescription" runat = "server" Text = '<%# Eval("ProductName") %>'></asp:Label>
</td>
</tr>
<tr >
<td style="border:0px;" ID ="tdAttributes" runat = "server">
<asp:PlaceHolder id = "placeHolderAttributes" runat = "server" Visible = "false"></asp:PlaceHolder>
</td>
</tr>
</table>
</ItemTemplate>
</telerik:GridTemplateColumn>
Control is added in ItemDataBound as. This code works,
</pre>
'htmltable,row and cells are declared
Select Case controltype
Case ControlType.TEXTBOX 'Constants declared
Dim textBox As Telerik.Web.UI.RadTextBox = New Telerik.Web.UI.RadTextBox
textBox.ID = "MYCONTROL"
tableCell.Controls.Add(textBox )
Case ControlType.TEXTAREA
Dim textBox As Telerik.Web.UI.RadTextBox = New Telerik.Web.UI.RadTextBox
textBox.ID = "MYCONTROL"
tableCell.Controls.Add(textBox )
Case GlobalControls.UCFormFields.FormFieldTypes.CHECKBOX
Case GlobalControls.UCFormFields.FormFieldTypes.DROPDOWNLIST
End Select
thisHtmlTable.Rows.Insert(0, thisTableRow)
thisTableRow.Cells.Add(tableCell)
thisTableRow.Visible = True
thisHtmlTable.Rows.Insert(thisHtmlTable.Rows.Count, thisTableRow)
Dim placeHolder As PlaceHolder
placeHolder = gridItem.FindControl("placeHolderAttributes")
placeHolder.Controls.Add(thisHtmlTable)
placeHolder.Visible = True
In item command , i want to retrieve the control, i can switch between the controls if i retrieve the placeholder... my problem is that in itemcommand, i can retrieve the Placeholder but when i try placeholder.controls.count, it returns 0 and cannot retrieve any control
i am trying the following code in itemcommand
item("ProductName2").FindControl("placeHolderAttributes").Findcontrol("MYCONTROL") 'this throws an error
'also tried
item("ProductName2").FindControl("placeHolderAttributes").controls.count 'this shows 0
Please provide help...
Thanks!!!

Hi Mark,
before the execution of the ItemCommand , you must redraw the grid as you are creating dynamic controls on ItemDataBound.

Jamil

Hi,
Thanks for replying.
I am not sure on how to redraw the grid. i mean, i am not sure on which event to use for creating the controls, so that the controls are available for itemcommand.
Can u please provide a bit more detail.
Thanks again.
Mark
