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.

hey thnks dude.. lemme try that

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.

Hi all,
In my application i am opening a window through javascript from the code behind on the click event of an asp button.
But the problem is when i am placing the button inside an update panel the window is not opening.otherwise it is working.
Can anybody give me any way to solve it.
|
|
|
|
|
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.

Hi,
I am working with the HTTP Post method to log the user into my framework. But when I run the page it does not redirect to the Page given in URL. What I am doing wrong?
Following is my code:
string strResponse;
string strPost;
protected void Page_Load(object sender, EventArgs e)
{
strPost = "txtUserName=abc&txtPassword=123";
UTF8Encoding objUTFEncode = new UTF8Encoding();
byte[] arrRequest = null;
Stream objStreamReq;
StreamReader objStreamRes;
HttpWebRequest objHttpRequest;
HttpWebResponse objHttpResponse;
Uri objUri = new Uri("http://www.mysite.com");
objHttpRequest = HttpWebRequest.Create(objUri) as HttpWebRequest;
objHttpRequest.KeepAlive = false;
objHttpRequest.Method = "POST";
objHttpRequest.ContentType = "application/x-www-form-urlencoded";
arrRequest = objUTFEncode.GetBytes(strPost);
objHttpRequest.ContentLength = arrRequest.Length;
objStreamReq = objHttpRequest.GetRequestStream();
objStreamReq.Write(arrRequest, 0, arrRequest.Length);
objStreamReq.Close();
CookieContainer cookieContainer = new CookieContainer();
objHttpRequest.CookieContainer = cookieContainer;
//Get response
objHttpResponse = objHttpRequest.GetResponse() as HttpWebResponse;
objStreamRes = new StreamReader(objHttpResponse.GetResponseStream(), Encoding.ASCII);
strResponse = objStreamRes.ReadToEnd();
objStreamRes.Close();
}
Thanks

First, you are not following the guidelines for posting here. Use the pre tags to format any code you post.
Of course it's not redirecting because you are not telling it to. All you are doing is writting, or attemtpting to, the content of the web request to the output stream of the same page. This is NOT the way to a redirect. Use Response.Redirect.
This is also not the way to authenticate users. I suggst you read up on forms based authentication.

I can show the date in the textbox txt1 but how to do it for txt2?

If you are using JavaScript then get access to the textbox (document.getElementById(...)) and set the value.
If you using a postback then you need to expose an event on the user control that the main page can subscribe to so it can receive a notification to set the text.
