I'm not 100% sure what you mean with "menu items are clickaable when is taken on them", but i guess, the menu is not hidden behind the shown image?

This has something to do with the z-index of the involed divs/panels/etc.

So you have to make sure that your menu-divs' (or whatever your menu consists of) have lower z-indeces than the elements displaying the image.

This is just a guess though.

Dear all,

I have to make a webservice that gets some data as parameter from the client and saves these into a database.
My question is what is the best way to make this? in wich format has to be the data? can i use a datatable/dataset? or each record separatly? or other ways?
the amount of records is each time various(till 2000 records).

Thanks in advance.

You can use dataset as well as datatable, but it will be better if you simple xml to pass as parameter and parse it at recieving end

For me, problem seems to be here, "&" is Unary AND operator and you are using it as Logical AND.
Try to use "&&" operator, its Logical AND operator used in if conditions.

I am not too sure whether it'll solve your problem, but i think error is for that only.
Try it. Smile | :)

Please check the following line.

if (IdentityValue == 1)
   ExistingAssociatetbl.Rows.Find(Sno = 1).Delete();

Some assignment is happening in the find method when it expects an object. Please check it.

Hi,

(1) If you have any access to "event viewer" of the hosting server, did you get any exception details there or any more information?
(2) I have seen you have provided a big code block, however did you identify which line it is causing the exception?

if you can do that it would be great so that we can help you more.

Thanks,

Hey hi..

this block actually

if (ExistingAssociatetbl.Rows.Count > 0)
{
IdentityValue = Convert.ToInt16(ExistingAssociatetbl.Rows[ExistingAssociatetbl.Rows.Count - 1][0].ToString());
IdentityValue += 1;
}

and also.. the stack exception shows error in this method too..
and the line is marked with two **

private bool CheckDuplicates(System.Data.DataTable dtCheckDuplicates)
{
DataTable dtDuplicateRecords = dtCheckDuplicates.Clone();

bool blnCheckDuplicate;

for (int iRow = 0; iRow <= dtCheckDuplicates.Rows.Count - 1; iRow++)
{
blnCheckDuplicate = false;
** string strCheckRow = string.Empty;
object[] arr = dtCheckDuplicates.Rows[iRow].ItemArray;
for (int iColumn = 0; iColumn <= arr.Length - 1; iColumn++)
{
if (dtCheckDuplicates.Columns[iColumn].ColumnName.Trim().ToUpper() != "SNO")
{
if (iColumn != arr.Length - 1)
strCheckRow += dtCheckDuplicates.Columns[iColumn].ColumnName + " = '" + arr[iColumn].ToString() + "' and ";
else
strCheckRow += dtCheckDuplicates.Columns[iColumn].ColumnName + " = '" + arr[iColumn].ToString() + "'";
}
}

if (dtDuplicateRecords.Select(strCheckRow).Length > 0)
{
blnCheckDuplicate = true;

}

if (!blnCheckDuplicate)
{
DataRow[] drs = dtCheckDuplicates.Select(strCheckRow);
if (drs.Length > 1)
{
lblError.Text = "";
lblError.Text = AdhocConstants.DuplicateTravelPlan;
return true;
}
}
}
return false;
}

thnks for the help..

I've never done search-related.
the search-content contains: musics,pictures,peoples etc.
so I have a few questions.

Search content from multiple tables and multiple Fields.

I do full-text indexing of these fields.

If I need to create a view that contains these fields?

then I write sql "select" from this view.

is right?

I hope someone can give a guiding learning resources.

Thanks.

Can anybody suggest how this can be done more efficiently and are there any microsoft tools (3rd party is not allowed in my project).

Any suggestions wold be welcomed.

Are you Registering any startup event for the Button in the codebehind to open the window?

If yes, ClientScript class would not work in UpdatePanel. You ScriptManager's Register function.

its because when postback occurs it removes javascript so to resolve this problem you require to register click event of the button again.
