I have a few applications/websites running with LINQ to SQL and the other day I decided to go ahead and optimize some of the queries, etc and I found that the size for variable length data types is derived from the parameter value instead of the column actual size? for example a column is defined as nvarchar(30). when I use linq to query that column with a value that's 5 characters long the parameter in sp_executesql will be defined as nvarchar(5)...this causes a major procedure cache bloat even for a small utility site that has a lot of queries is there a way to optimize this?

I have an array called"List" with 1 item and a gridview "grdWorkingDays" with two columns.
In the First column, I want to display the working days dynamically from the arraylist and in the second column I need to display a dropdown with CL/PL/Halfday(Which has values from a database table and is already written in a method)Â against each date of array list.
The code is:
int NoOfWorkingDays = List.Count;
for (int j = 0; j < NoOfWorkingDays; j++){
String Date = ((Label)grdWorkingDays.Rows[j].Cells[0].FindControl("lblLeaveType")).Text;
Date = List[j].ToString();

"Index was out of range. Must be non-negative and less than the size of the collection." pointing to the 1st row of for loop.

FYI, the array count is being calculated correctly as "1" .
i'm doing a page which allow user to choose date from calender extender using a text box.. after choosing the date, the text box will have the event ontextchange that will display all data related to that date without user clicking any button.. i will be using a range validator to check whether the user access to more than 2 days from the system date..
the problem i'm having is,
- after everytime i choose the date, the range validator will keep disappear due to the auto post back which i use in order to make the text event (ontextchange) work..
- i need some advise on how to solve this problem?? been trying to solve it for 2 days alread T.T

I have a "database explorer" page that is desgined to be pointed to an unknown database and allow users to browse the data, so it basically uses the SQL system tables to develop its queries and pull in data to tables using auto-generate columns.The problem that I have is that I would like certain types of columns to have certain formats and I'm wondering the best way to go about it. I could format the column in code in the RowDataBound event I assume, but I'm wondering if there some better standard way to do this? Is there a setting of any kind that I can use? For example I want all of the datetime fields to be formated for short date, like {0:d}, I want decimal fields to have 4 decimal places, etc.

View 3 RepliesMy application work in this ways. I got a database collect data from 20 sensors. Database holds Temperature and DateTime data/Records from sensors. So i would like to make it whenever i view the chart, it will plot a line chart one by one according to the temperature and timestamp(DateTime). Which mean my X axis is a colleborate time on that particular date.I already design a in the way that the line chart will plot base on both dropdownlist, Sensor ID and Date. So it will work like whenever i select a Date or ID it will read the records from database table temperature.
View 9 RepliesI am working with a chart control and on the Y axis i have numbers that fall between millions and billions.
The numbers on the axis themselves are not formatted and as such can be difficult to read. I wanted to know if there was a way for me to format the value that appears on the axis itself to be coma seperated?
here's what the Y axis looks like
600000000
300000000
100000000
numbers are just hard to read. How do i format them with coma's or even add a label saying (Millions) and then displaying only 100, 300, 600 etc
I have 2 series in the same chartarea. Both contain values by year (x axis). The problem is if one series does not have data for a given year, the chart will display the first value in a series on the first tick mark whether it matches the xaxis label or not.
Example:
[Code]....
Notice the 2009 value for series1 appears in the first column and the Xaxis now has 2 2009 tick marks. How do I get the values to appear on the correct X axis marks?

I am making a chart on a asp.net page (visual studio 2010). I am "summing" time. As long as the sum is not more than 24hours, all goes well. But if the sum is bigger than 24hours, then I get a "Not a legal Oleaut date" error.
This is my code (simplified) :
Chart1.DataBindCrossTable(_dataset._table.AsEnumerable(), "factor",
"week",
"time",
"");
Chart1.Series[0].YValueType =
ChartValueType.Time;
duurhhmm is a DateTime field. "factor" and "week" are my groupings for the x-axis.
first question : what to do about the "not a legal oleaut date" ?
second question : on the axis I see 00:00,06:00, 12:00,18:00 and then again 00:00,06:00, etc... But I would like to have 24:00, 30:00.
i created a chart in Excel, but now I am having the time of my life to create the same chart in a control.
If you can see on the bottom I have converted the labels to percentages.
In excel I am using a series of data cells to create the bottom labels (0-8 with a .5 increment).
The Y-axis is done with a fixed maximum value of 2 and the labels are percentages as well. How do I get those same axes on the chart control?
I´ve got a chart control (column type) and must show many elements at y axis, but when system generates the chart draw, it´s shows only odd elements: For example: My chart must show a colunm containing systems (x) and error incidences (y):
1. SIEMP
2. SISOUT
3. SIGTI
4. SISFIN
5. SISPL
6. SISTER
But it´s only shows:
1. SIEMP
2.
3. SIGTI
4.
5. SISPL
6.
I must set a parameter that forces "all" series to be showed.
I have a fairly basic line graph which is bound to a SQLDataSource control. The graph displays perfectly, but I want the labels on the X-axis to display vertically rather than horizontally.
I have used the following code to try and do this but it is having no effect:
<AxisX Title="Patient Safety Submissions" IsLabelAutoFit="True">
<LabelStyle Angle="90" interval="1" />
</AxisX>
