however, i am getting the exception, unable to evaluate expression because the code is optimized and usually, you fix it by adding a false to your response.redirect.
is it possible to make a Linq query dynamic in the following pseduo code (to show what I'm trying to do)
[Code]....
where a2 and a3 and a4 are being populated from user controls and only one will apply. So query is done by state, zip or by city, but not by more than one, so the other two would be null. So the operator is really "OR" but I haven't found anything on a "or" or "whereOr" operator.
I understand that if you put a Response.Redirect inside a try-catch that you're going to get this error unless you specify the 2nd param of the redirect as false.But even looking at this article (PRB: ThreadAbortException Occurs If You Use Response.End, Response.Redirect, or Server.Transfer) I still don't understand why I have to set this to false for this particular line of code...we've always had true for that param until I wrapped that in a try-catc
View 1 RepliesI want to export the data to pdf in which table has 150 columns.
When i save the file in directory , the file is opening. whereas when open it directly some box type is displaying.
And also am getting exception in Response.End() method which is given below
"Unable to evaluate expression because the code is optimized or a native frame is on top of the call stack."
I am using asp.net 2.0 with c#.
" myReportDocument.ExportToHttpResponse(CrystalDecisions.Shared.ExportFormatType.PortableDocFormat, Response, false, rptName);"
As soon as compiler execute this statement i get error
" [System.Threading.ThreadAbortException] = {Unable to evaluate expression because the code is optimized or a native frame is on top of the call stack.} "
What will be the possible reasons for the error.
Although it throws execption but it will allow to convert report when i deployed my site using http but when i deployed my site using https then it will shows error .
I'm using CRv9 and want to make use of Google Charts API for generating QR code on fly (in asp .net) and display it in the Crystal Report in a PDF format.I have spent the whole day looking for solution with no luck. The way we output the report is we use .rpt file, feed it with data and use Response.OutputStream to feed to browser. No CrystalReportViewer control hence CSS solution is not an option.
Now, I got as far as added an OLE Object from file with Link, which I would be overwriting every time the new QR code is generated. I apreciate that CR requires it to be a bitmap, so I was planning to download and convert the google's generated PNG file to BMP, that's not an issue. The problem is that Image in the report does not update after I replace the file. Meaning, it displays the original image, which was added as an OLE Object.
If I open this report in CR designer, the image gets refresh/updated and I'd have to save changes to the report to see this new image next time I generate a PDF file.The question is really how to achieve a dynamic image in Crystal Reports 9? Remember, Picture object did not have a Graphic Location property until vXI, so I cannot use that.
Manipulations with DataSets is not an option either as we're not giving report a datasource, instead we just map the fields with FormulaFieldDefinitions.

At my current place of employment, a university, we are going to take a stab at making a mobile browser-oriented section of our web site. I was wondering if anyone could direct me to some good resources that they know of for such a thing. Primarily, names of books would be nice, but any kind of resource at this point would be extremely helpful. We are approaching this as more of an HTML project at the moment, so the resources don't need to be Asp.Net based, but such things would be great too.

I have this query for getting data through Entity Framework, which works today. Thing is, i want to create the query dynamically, i.e build it up in blocks, but i can't figure out how exactly to do it. I believe if i can somehow save one of the values that i retrieve in the beginning i can do it, but now i retrieve it twice (probably a bit slow as well? Unless the compiler fixes it before quering). Makes sense? Here is the LINQ:

I.e based on if various variables have values.
I've created a Dynamic Data project with an Entity Framework model. It works nicely. But, right now it shows all my database tables with the db column names - which aren't always the most friendly (e.g. address_line_1). How can I got about giving these more friendly column titles that will display to the end user?

View 2 RepliesI am making one pointing web application. There are different Points like 20 Points, 50 Points, 75 Points,etc. These are saved in Database.This Points are belongs to some Vendors. Customer will take the Points from Vendors.want to show the summary in gridview like how many customer use 20 points, how many customer use 75 Points, etc.I want the Gridview Like below
Vendor Name 20 Points 50 Points 75 Points
ABC 5 7 8

We currently allow users to store HTML in the database. Would like to allow them to add scriptlets to their HTML email templates that would be executed at run time. Example:
[Code]....
What I want to have happen is to have the scriptlet execute before being rendered to the output stream.I found an article from Rick Strahl that is about 8 years old:
http://www.west-wind.com/presentations/dynamicCode/DynamicCode.htm. It looks like the code at the very bottom is exactly what I want, but when I tried it in my .Net 4 app, it didn't work. I get the error:
2 Errors:Line: 0 - Metadata file 'RemoteLoader.dll' could not be found
Line: 0 - Metadata file 'wwScripting.dll' could not be found
I presume this is from the Generated source code. Not sure how I tell the Generated source code where those 2 DLLs are.
Is there a different/better way of doing this these days?
I generate dynamic grids based on a count value returned from some DB tables. the code for it goes like this : I give and Id to each grid that is generated.
if (myDataList1.Count >= 1)
{
for (int i = 0; i < myDataList1.Count; i++)
{
//retrieving the exact i count from pageload
ViewState.Add("newCount", i);
//creating the dynamic grid with its corresponding gridview properties.
grvDynamic = new GridView();
grvDynamic.ID = "GridView" + (i+3);
grvDynamic.AutoGenerateColumns = false;
grvDynamic.RowCreated += GridViewRowCreated;
grvDynamic.RowDataBound += grvDynamic_RowDataBound;
//adding bound field columns to retrieve data from stored proc
BoundField metric = new BoundField();
metric.HeaderText = "Goal ";
metric.DataField = "metric";
grvDynamic.Columns.Add(metric);
BoundField mtd = new BoundField();
mtd.HeaderText = "MTD";
mtd.DataField = "value_MTD";
grvDynamic.Columns.Add(mtd);
BoundField goal = new BoundField();
goal.HeaderText = "Tier Level Achieved";
goal.DataField = "value_goal";
goal.HeaderStyle.Width = Unit.Percentage(10);
grvDynamic.Columns.Add(goal);
BoundField you1 = new BoundField();
you1.HeaderText = "Month End";
you1.DataField = "firstLevel_you";
grvDynamic.Columns.Add(you1);
BoundField you2 = new BoundField();
you2.HeaderText = "Month End";
you2.DataField = "secondLevel_you";
grvDynamic.Columns.Add(you2);
ButtonField singleClick = new ButtonField();
singleClick.CommandName = "clickHyperlink";
singleClick.Visible = false;
grvDynamic.Columns.Add(singleClick);
BoundField metricId = new BoundField();
metricId.HeaderText = "Metric Id";
metricId.DataField = "metricID";
metricId.Visible = true;
grvDynamic.Columns.Add(metricId);
//binding the gridview to data.
grvDynamic.DataSource = data;
grvDynamic.DataBind();
grvDynamic.Columns[5].Visible = false;
}
}
protected void grvDynamic_RowDataBound(object sender, GridViewRowEventArgs e)
{
//this basically gets the metric Id's of rows with the ishyperlink flag set to 'Y'. I need to make these particular cells clickable var isClickable = (from md in myDataList3 where md.IsHyperLinkFlag == 'Y' &&
md.value_MTD != null select md.metricID).ToList();
if (e.Row.RowType == DataControlRowType.DataRow)
{
// Get reference to button field in the gridview.
LinkButton _singleClickButton = (LinkButton)e.Row.Cells[5].Controls[0];
if (isClickable.Contains(Convert.ToInt32(e.Row.Cells[6].Text)))
{
e.Row.Cells[1].Style["cursor"] = "hand";
e.Row.Cells[1].Style["color"] = "blue";
e.Row.Cells[1].Style["textdecoration"] = "Underline";
e.Row.Cells[1].Attributes.Add("onClick", "window.location ='../HeaderPages/page2.aspx' ");
}
}
}
This code works perfectly fine , depending on the ishyperlink flag in the database...specific cells in the grid are made clickable and then redirected to page2.aspx My Issue: I need to capture which specific cell in which specific grid the user has clicked. store some information in sessions based on the cell clicked and use that information in page2.aspx.
