Look, my friend;
The edit command of the grid view control fires the events:
- RowEditing: where you set the
EditIndex property. this will load the editing template to render the row you wish to edit. - RowCancelingEdit: fired when edit is canceld.
- RowUpdating: fired when you click the update command. Here you make the actual editing action.
- RowUpdated: fired when the update is done.
you can refer to this page[^] for a good example

You have two options.
If all of your users are using a recent browser, you can use a Data URI[^] to embed the image. It won't work in IE7 or earlier, and IE8 support is limited.
public static string GuessImageMimeType(byte[] data)
{
string result = null;
if (data != null && data.Length > 3)
{
if (data[0] == 71 && data[1] == 73 && data[2] == 70)
{
result = MediaTypeNames.Image.Gif;
}
else if (data[0] == 137 && data[1] == 80 && data[2] == 79)
{
result = "image/png";
}
else if (data[0] == 66 && data[1] == 77)
{
result = "image/bmp";
}
else
{
for (int index = 0; index < data.Length - 2; index++)
{
if (data[index] == 255 && data[index + 1] == 216 && data[index + 2] == 255)
{
result = MediaTypeNames.Image.Jpeg;
break;
}
}
}
}
return result;
}
public static string BuildImageUrl(byte[] data)
{
if (data == null || data.Length == 0) return null;
var sb = new StringBuilder("data:");
string mimeType = GuessImageMimeType(data);
if (!string.IsNullOrWhiteSpace(mimeType)) sb.Append(mimeType);
sb.Append(";base64,");
sb.Append(Convert.ToBase64String(data));
return sb.ToString();
}
<asp:Image runat="server"
ImageUrl='<%# BuildImageUrl((byte[])Eval("visPic")) %>'
/>
If you need support for older browsers, you'll need to create a generic handler to load and return the image based on the ID, and set the ImageUrl to point to that handler:
<asp:Image runat="server"
ImageUrl='<%# Eval("ID", "DisplayVisitorPicture.ashx?ID={0:D}") %>'
/>
There's an example of this approach here: Image Handling In ASP.NET[^]

You have to use OCR in order to convert image into text:
Here you have useful links:

Hi! I'm teaching some basic ASP.NET.
I have looked at a solution for login-page.
There is the built in forms-authentication but I seem to work bad.
Login works sometimes and sometimes not. Doesn't seem so stable or maybe I am doing something wrong.
Is this something you would use on a live site?
What else should you use?

Given that Forms Authentication has been around for 12 years, and is used by a huge number of sites, my money's on option 2.

Man;
You know something, Microsoft is the opposite of stability.
Windows itself is not stable that suddenly you get that stupid blue screen and you would loss all your work. Because of that you shouldn't bet on Microsoft product so, you wont loss your money.

Thankfully, I haven't seen a BSOD for years, and even then it was dodgy hardware that caused it.

Yes sir it's very difficult understand about the forms Authentication, I have used many time in live project, but every time new problem faced.After some searching on google some idea get, then resolve problem. I used every time web config Authentication, it's simple according to me.

Hello,
If I search (api/test/cusip=00163&isin=555), I get 10 records showing both of cusip and isin value and 9 records with price_type= cr and 1 record price_type= tk.
However, if I run the following query (api/test?cusip=00163&isin=555&price_type=cr), i only get results from cusip parameters (00163) and nothing from isin and they are also not in a descending order.
This is what I have so far:
public HttpResponseMessage Get([FromUri] Query query)
{
var data = db.database.AsQueryable();
int pageSize = 10;
if (query.price_type != null)
{
data = data.Where(c => c.Cover == query.price_type);
}
int total = data.Count();
var filteredData = new List<IQueryable<database_BWICs>>();
if (!string.IsNullOrEmpty(query.isin))
{
var ids = query.isin.Split(',');
foreach (string i in ids)
{
filteredData.Add(data.Where(c => c.ISINs != null && c.ISINs.Contains(i)));
}
}
if (!string.IsNullOrEmpty(query.cusip))
{
var ids = query.cusip.Split(',');
foreach (string i in ids)
{
filteredData.Add(data.Where(c => c.CUSIP != null && c.CUSIP.Contains(i)));
}
}
if (filteredData.Count != 0)
{
data = filteredData.Aggregate(Queryable.Union).OrderByDescending(c => c.UploadDate).Take(pageSize);
}
if (!data.Any())
{
var message = string.Format("No data was found");
return Request.CreateErrorResponse(HttpStatusCode.NotFound, message);
}
if (query.price_type != null)
{
data = data.OrderByDescending(c => c.Cover == query.price_type).Take(pageSize);
}
return Request.CreateResponse(HttpStatusCode.OK, new { total, data });
}
}
I have tried debugging the issue many times on the following line with search string - http://localhost:32118/api/test?cusip=00163&isin=555&price_type=cr . The application crashes on the data parameter "data = {System.Data.Entity.DbSet<multi.database>} ". I am little unclear what this issue mean?
if (query.price_type != null)
{
data = data.Where(c => c.Cover == query.price_type);
}
Am I missing something? if so, is their a better way to do this? Thanks in advance for your help and time.

Sir;
I don't know what are you trying to do, but I believe that you chooses to do it with the hard way. I don't understand why you applied the each filter alone then you applied 'Union All'.
and I think that you need to mention that you are using ASP.NET MVC Web API.

Hi,
I have updated my original post and managed to get half of the issue resolved. I am currently stuck on the price_type parameter on filtering query with pagesize and orderby function.
If anyone could help me out on this issue explained in my original post, that would be very helpful.
Many thanks.

Ma'am;
From your code, I can extract that your data table has columns:
- Cover: to be match with price type(restrict the data set)
- ISINs: filter
- CUSIP:filter
- UploadDate: descending order
first,you restrict the data to price type. Then you select ISIN matching records and the CUSIP matching ones from the restricted data. lastly, you order the filtered data according to the upload date.
After that you reorder the overall data according to the price type.
In the first request query 'cusip=00163&isin=555' you didn't specify a value for price_type so the lines
if (query.price_type != null)
{
data = data.OrderByDescending(c => c.Cover == query.price_type).Take(pageSize);
}
wont execute. But inn the request 'cusip=00163&isin=555&price_type=cr' you restrict the data to cr price type and execute the above statement which will cancel all ordering.
my recommendation is to remove these lines, and accept me as a friend on facebook.
if you need any further help you should tell me what your data is and what you want to do with it.
by the way what about the number 786?!!
Help people,so poeple can help you.

Thank you for your response. I am writing to inform, I manage to get the issue resolved by adding the orderby and pagesize filter to filterdata method.
Thank you for your time and suggestions.

Anybody familiar with Telerik's grid products...
We had code that previously implemented the telerik grid
@(Html.Telerik().Grid()<myTransactions>
.Name("Transactions")
.ClientEvents(events => events.OnLoad("TransactionsGrid_onLoad"))
.ClientEvents(events => events.OnDataBound("TransactionsGrid_onDataBound"))
.DataBinding(dataBinding => dataBinding
.Ajax()
.OperationMode(GridOperationMode.Client)
.Select("TransactionsAjax", controller))
We have recently migrated to Telerik's Kendo grid, and changed the code to the following:
@(Html.Kendo().Grid<myTransactions>()
.Name("Transactions")
.AutoBind(true)
.Events(events => events.DataBound("TransactionsGrid_onDataBound"))
.DataSource(dataSource => dataSource
.Ajax()
.ServerOperation(false)
.Read(read => read.Action("TransactionsAjax", controller))
.PageSize(15))
In addition to the grid, the page has 3 other fields; a combobox and 2 date fields that filter the grid. The filtering works fine.
However, the printer friendly button calls TransactionsAjax for the Kendo grid and removes all filtering that was applied. The original Telerik just rendered the existing grid as print friendly without making a redundant call to TransactionsAjax.
Since the desired data to be printed is already filtered and available on the screen there is no reason to repeat the call. Is there some grid configuration setting I am missing that would stop the undesired call from happening?

Posting my findings in case somebody runs on to a similar issue, maybe it will be helpful (plus the code to set the select elements in the cloned div is cool  ).
I've worked around the issue. Something about the first line of javascript in our printer friendly function causes the Ajax call to occur with the Kendo grid where it didn't cause it with the original Telerik grid. Changed javascript function to use jQuery clone and things are working now.
Old code:
function ShowPrinterFriendly() {
$("#printerFriendlyContent").html($("#mainContent").html());
New code:
function ShowPrinterFriendly() {
var $originalDiv = $("#mainContent");
var $clonedDiv = $originalDiv.clone();
var $originalSelects = $originalDiv.find("select");
$clonedDiv.find("select").each(function(index, item) {
$(item).val($originalSelects.eq(index).val());
});
$clonedDiv.appendTo("#printerFriendlyContent");

Suppose my stored procedure returns multiple datatable then how to manage that datatable in DataSet.xsd file
modified 6-Feb-14 3:30am.
|
|
|
|

Unfortunately If multiple result sets are retrieved through a single query, only the first result set is processed, and all other result sets are ignored.
Therefore, I suggest using one of two possibilities:
(1) Split the procedure into two separate procedures - one which returns data from EMP, and one from DEPT - and access the new procedures as two separate datasets.
(2) Union the two separate queries (with an additional column to indicate which query produced each row) and filter or conditionally format your report appropriately. The unioned query might look something like this:
SELECT EMPID ID, ENAME NAME, JOB JOB_LOC, SAL, DEPTID, 'EMP' SOURCE
FROM EMP
UNION ALL
SELECT DEPTID ID, DNAME NAME, LOC JOB_LOC, NULL SAL, DEPTID DEPTID, 'DEPT' SOURCE
FROM DEPT

Hello Everybody,
I would like to know if there is something I am missing why my ASP.NET is not running the script that is embedded in the master page, I imagine that it should be running in any page using the master page (where I have the event embedded) as shown in my screenshot but to my surprise it doesn't run the alert message ..
When I click any of the images I am not seeing the alert box that I am expecting as a response to the click event ..
My code is shown below .. any help much appreciated .. thanks again:

Put your script in separate element after jquery and it should run correctly.
