SQL Reporting :: Hide ReportViewer Until Render?
Jan 12, 2011
For many of the pages I build, I don't wish to have the ReportViewer visible until firing an event such as a button click. Using .Net 4.0 and ReportViewer10, however, throws the error "Message: Sys.ArgumentNullException: Value cannot be null. Parameter name: panelsCreated[1]" if you try to keep a panel containing the ReportViewer hidden until after a button click.Since I couldn't find much about this topic online, I'd basically been working around this for some time until I figured out today that if you reset the ReportViewer ReportPath in the code behind in the button click (even if it's the same path as in the aspx page), you can successfully keep the ReportViewer hidden until the button click.

I have created many reports in my ASP.Net 3.5 app's and using VB Code-behind. I have the following code that will take the report from the reportviewer and on a click of a button, export it to PDF. So now, I can hide the reportviewer and just have the button click events generate my PDF's. I do not know how to tweak this code to enable me to print directly from another button's click event without the reportviewer being visible.

What I am looking for is how to fill the tableadapter that I am using in the .xsd dataset file to the I do not have to incorporate reportviewers anymore?I know my code above would need to be adjusted so that its not looking at ReportViewer1 for the Report/Data... But I do not know how to do this.

I'm using the ReportViewer control on my .aspx page which displays a single report based on various user parameter selections. Dropdown2 is dependent on the DropDown1 selection (i.e. the user selects Unit A from DropDown1 and that results in 10 selections under Dropdown2, or the user selects Unit B from DropDown1 and that results in 15 selections under DropDown2, and so on). The user makes the selections, clicks the "Run Report" button, and the report displays as expected. The user then can export to Excel or PDF
I've received a request to allow users to run the report for all possible selections and export to their desired format rather than having to run the report for each separate DropDown1 and DropDown2 selection. So in other words, they don't even want to see the report on the screen, they just want to be able to click a button that runs the report for all possible parameter selections and export it to a single Excel or PDF document.

We have a table with report name and a bit column which indicates whether a report is exportable to PDF or not.
Now depending on this column value, I need to hide the PDF option from the dropdown in the reportviewer.
I tried iterating the controls on the webform to find out a dropdown but everything is rendered as div elements.
The other approach I tried is this.
Since the reportviewer is on a .aspx page, I wrote a javascript function which will pull out the value from the hidden field on the page
and hide the div element. Works fine when the page loads the first time. But if I were to change the parameters and hit 'View Report'
again, somehow the javascript function never gets called and the div never gets hidden.
Here is the code for the .aspx page.

I have a ReportViewer control on an ASP.Net page and an RDLC set up that uses a TableAdapter that pulls one record. This works fine.I'd like to have the *same* RDLC use a different TableAdapter (schema of table is the exact same, but may have multiple records). I've tried putting two DataSets in my RDLC and having the code dynamically select which one to use, but it's not working quite right for me.

i am using asp.net 2.00(visual studio 2005 std edition) i have designed a report in reportviewer which runs fine on localhost server but when deployed on server it shows no data from other computers , after searching net i found that dynamic binding of dataset and reportviewer is required , so i entered following codes (dtgraph is data table name and graph.axd is data set name ) the code gives error that dtgraph is not declared , where i should declare it / any solution
ReportViewer1.Visible =
Protected Sub Page_Load(ByVal sender
As Object,
ByVal e As System.EventArgs)
Handles Me.LoadTrue
ReportViewer1.ProcessingMode = Microsoft.Reporting.WebForms.ProcessingMode.Local
rep.Refresh()
rep.ReportPath =
Dim rep As Microsoft.Reporting.WebForms.LocalReport = ReportViewer1.LocalReportDim
rds As Microsoft.Reporting.WebForms.ReportDataSource =
New Microsoft.Reporting.WebForms.ReportDataSource()"graph.rdlc"
rds.Name =
"graph_dtgraph"
rds.Value = dtgraph.tables[0]
End
End Sub

I have a reportviewer that uses a dynamically generated RDLC (which means the RDLC is created at run-time through an XSL) to generate reports. I have no issue loading the report. My problem is with its toolbar. It is always disabled. I can't perform search, change the report size, or export the report to another file format.

I am new to this sql reporting service. But anyhow by surfing I am able to bind the report but i was stuck in image display.Anyways, i also managed that. But the real problem is whenever i was keeping a image control in rdlc report i was having session prob. If i remove the image control then as usual report works fine.either for session problem or for image display. I am keeping the image name in database but for binding the rdlc report i am using a store procedure which return the path (static) concating with the image name(kept in database).

I am using Visual Studio 2005 and Report Viewer to generate a few reports that I extract from a MS SQL 2005 DB. Everything is working fine, but I want to be able to pass 2 parameters from my ASP.NET C# file to the report file (.rdlc) and show it on the generated report.
My C# file has these lines, which I believe pass the parameters off

We use MS ReportViewer version 10.0.0.0 to pull the report from SSRS to ASP page.
Part of ReportViewer source code is shown below: (thru MS Developer Tools)
<div id="ctl00_RootContent_c_ReportViewer_ctl10" style="position: relative; width: 100%; height: 100%; overflow: auto;" _events="[object Object]" control="[object Object]">
We'd like to change the style="position: relative..." to style="position: static..."
How can we do it?
It seems that whenever ReportViewer refreshes, the CSS values will be reset back to default one.
How can I create my own CSS file for ReportViewer?

I'm using the ReportViewer 2008 control embedded in a web page. One of my reports
supports drilling down through the data.
This produces a strange behaviour with the scroll position.
When I click the + icon to toggle visibility, the item clicked expands, then jumps to the top most part of the ReportViewer control.

I try to use a reportviewer for a localreport. The page ran without error but the ReportViewer didn't display, not even the control itself. To verify I did get the data from the SQL server, I bind the same datatable to a gridview on the same page at the same time. The gridview displays the data without any problem and the reportviewer is just a blank area.
