Windows forms and Asp.net have not changed but the WPF version doesn't include the traditional way of viewing the report i.e. the report viewer doesnt include a direct report source. Did anyone figure out the new way of doing it (I am not interested in the examples of winform interop)as Google didnt yield much results?

Before defining the report source you should add a viewercore.
Example
reportViewer.ViewerCore.ReportSource = CrystalReport1

Hi, I have developed an application using Silverlight3 and WCF where I am fetching some data from database and binding to a datagrid.For small resultsets the application is working fine.But for large resultsets it gives an error at EndGet Method.
I checked the buffersize,maxReceivedMessageSize,receiveTimeout,closeTimeout,
openTimeout,sendTimeout.All are set to suitable values.
Can anyone help on this issue?

Increase those values according to your requirement, then it'll work.
|
|

<pre>
&lt;binding name="BasicHttpBinding_IOMSService" closeTimeout="00:50:00"
openTimeout="00:50:00" receiveTimeout="00:50:00" sendTimeout="00:50:00"
maxBufferSize="2147483647" maxReceivedMessageSize="2147483647"&gt;
&lt;security mode="None" /&gt;
&lt;/binding&gt;
</pre>
maxbufferSize,maxReceiveSize is set to the maximum integer value.
senTimeout,receiveTimeout are given.....do I really need to increase them??plz look at the values for them....

Increase sendTimeout to a bigger value and try again.

Try by increasing the sendTimeout. See here.

Increased the sendTimout to 10:20:00....but still getting error

Try enabling gzip compression on the service.
If that does not work, I give up!
And I hope you increased the maxbuffer size in your config file.

I checked the WCF with Fiddler...for large resultsets it also throws an exception saying "the connection closed unexpectedly".

Hi,
I need to style dataGrid rows for different background colors for alternate rows, different backgroundColor for hover and on selection I want to show a details template and on selection I also want a dotted blue border on the DataRow.
To achieve this, I create two different dataGrid styles, one for Datagrid where no row is selected and one for datagrid where a row is selected.
To apply styles I am handling SelectionChanged event of Datagrid. I am posting my code to get better idea.

</code>
in code behind Selechanged event:-
<code>
private void dataGridAddress_SelectionChanged(object sender, SelectionChangedEventArgs e)
{
object selectedItem = e.AddedItems[0];
DataGridRow selectedRow = dataGridAddress.ItemContainerGenerator.ContainerFromItem(selectedItem) as DataGridRow;
selectedRow.Style = this.Resources["DatagridRowStyleRowDetails"] as Style;
foreach (var item in dataGridAddress.Items)
{
if (item != e.AddedItems[0])
{
var dataGridRow = dataGridAddress.ItemContainerGenerator.ContainerFromItem(item) as DataGridRow;
dataGridRow.Style = this.Resources["DatagridRowStyleLocal"] as Style;
}
}
}
</code>
Styles are working ok as per requirement but if rows are selected rapidly then application crashes and throws exception
"The specified Visual is not an ancestor of this Visual."
Any idea how to fix this. I googled and found out that it is a bug, any one knows any workaround.
Thanks for reading,

Hi Experts,
I have created a user control in windows application and used it in wpf.
The user control is in a seperate project and solution than that of wpf.
I have exposed some properties in the user control and tried to use it in a wpf form.
I have used it in the WindowsFormsHost element and also added WindowsFormsIntegration reference.
I am facing the following problems:
1. I am able to see the user control in the toolbox but it is disabled.
2. I am able to design the user control in xaml and give values to properties. I am also getting the properties in intellisense but the same is not getting reflected/applied during design as well as run time.
3. I am not able to see the control in the properties window even after selecting it. I am just able to see WindowsFormsHost in the property window.
I am not able to find any sample project or explanation of this in code project. If there is any then please do let me know.
Also I am able to use this user control in a windows application very easily and it is working fine. Am i missing anything for wpf?
I can give the source code if required but i dont think it will be of much help as i have not done anything fancy.
Please help!
Thanks in Advance!
Regards,
Samar

Use a regular expression to pull out the <a> tags. BTW - I'm curious. How is this related to this forum?

Thanks for posting the solution.
You could however format it using PRE tags to make it more readable.
