Problem passing a text box value from aspx.cs page to SelectParameters in aspx page

Hi,I would like to take a value from a text box and pass it as a search parameter to my database. I get the value from my code behind page as follows: protected void btn_click(Object sender, ImageClickEventArgs e)      {           AccessDataSource1.SelectParameters["inputValue"].DefaultValue = TextBox1.Text;           string test = AccessDataSource1.SelectParameters["inputValue"].DefaultValue;                      //string inputValue = TextBox1.Text;          //Response.Write(inputValue);         // AccessDataSource1.SelectParameters.Add("@name", inputValue);          //Response.Write(@inputValue);                              } protected void btn_click(Object sender, ImageClickEventArgs e)     {          AccessDataSource1.SelectParameters["inputValue"].DefaultValue = TextBox1.Text;          //An alternate option I have used is          //string inputValue = TextBox1.Text;         // AccessDataSource1.Selec

Passing Linq Statement between master and content page


I usually work with windows forms, and am just starting to work with ASP.Net, so appologies if this is a dumb question!

I have a master page which has a search button on it. The results of this are built up using a Linq statement and if there are any results, I want to display the results in a contents page.

On the masterpage, I have the following code:

Private _res

    Public Overridable ReadOnly Property SearchRes()
            Return _res
        End Get
    End Property

 Private Sub DoSearch()
   'some code to get a linq result

    If res.Any Then
            _res = res
            Server.Transfer("SearchResults.aspx", True)
            'no results
            LabelNoRes.Visible = True
        End If
 End Sub

On the SearchResults.aspx page I have this code.

Dim m As pxSite = CType(Page.Master, MasterPage)
        If m.SearchRes IsNot Nothing Then
            Label1.Text = "Results found = " & m.SearchRes.Count
        End If

m.searchRes is always nothing. 

What am I doing wrong here?


reference from menubuttons to text parts in article on the same page


Hi, I'm searching now for hours but couldn't find it.Cry

In my menu i have several buttons which (by a <a href..) should go the a part of an article that is in the same form.

Menu button : What is a database should go to the page default.aspx and in there is an article published.
A part of this article is having a piece of text about "what is a database"

Menu button: how to make a query should go to this same article in the same page but then to the part that is have the piece about the query. The next could be an example of what i'm doing:

    <li><a href="default.aspx ?????>what is a database</a></li>
    <li><a href="default.aspx ?????>what is a query</a></li>

Where my question marks are, there should be a connection to that particular piece of text.
In each article part there is an ID="text1" and the second part id="text2"

How shoudl i do that, Should i use a question mark.
Please give me some guidance how to structure the <li> statement or a pointer where I can read about it.


passing page title through a param


Hello all,

   I am new to ASP.NET, and was wondering how to pass a Page title through a parameter.  In classic ASP I could just use something like: <title><%=Pagetitle%></title> but I cannot seem to get this to work in ASP.NET. 

Thank you in advance,

Why does text and page formating changes randomly?

Hallo there, First of all I don't know if I am posting in the right forum, so let me know if there is another forum for this issue. My form text and entire page formating changes once a while and I don't know why. e.g. font color, background color of certain paragraphs or table look changes, it seems randomly, I think it has something to do with the style but I don't know how to avoid this repeated text formating loses. In details: U am using Visual Studio 2010 Professional and is set for Visual Web Development. I create a new form e.g. default.aspx link it to a master page and the master page is linked to a css file (style sheet file) that contains only general and basic formatings and I hardly change any thing in this css file. I format my default.aspx. and later the formating chanegs by it self and I have to change it back manualy. Most of the time I have to create a new form. link it to the master page and copy the text, tables and so on from the original page to the new page and then delete the original page. but even the new page chnages later. and so on. I don't know how to avoid that! Any idea's? Thanks in advance  Michael Najar wishes you great day

I need help with the syntax for passing a record field value from SSRS to an asp page

I have tried several variations without success.  Here is where I am now.  The goal is from inside Report Manager report, link to an asp page with a filed value. This is from the expression line of the Jump to URL entry. Also I am trying to open a new page http://www.whereever.com/CSSurvey01.asp?RecordID=" & Fields!respid.Value            

Consistently running out of page file memory with full text indexer

Using MS SQL Server 2008 SP1 x64 Standard Edtion on Windows 2008 R2 Enterprise, I'm about to full-text index for the first time 1 table and 2 views. The table contains about 250'000 entries with a data space of 180 MB. As soon as I activate the full text indexing, the fdhost.exe task starts to consume slowly but surely all the available page file space (this can be easily watched using the Resource Monitor and the Commit Charge graph on the memory tab). Once all the virtual memory has been consumed, the server becomes unusable since it can't open any new windows any more, and RDP stops working. The machine specs are as follows: 12 GB of RAM 80 GB free on hard disk out of 136 GB 8 CPUs Custom size paging file with sizes between 24 GB - 60 GB (originally, this was system managed size, but then the server ran out of memory sooner) Max SQL server memory set to 6 GB (first 10 GB, then 8 GB) I've set the max fulltext crawl range to 8. During the indexing, the 8 CPUs are bit busy for a while, but not excessively. What is astonishing is that there is almost no use of physical memory during the indexing (I can see an increase from 2 GB to 3 GB which still leaves plenty of RAM available). Does anybody have an idea how I can convince fdhost.exe to consume physical memory and leave the paging memory alone? Or what else can I try?

Read a text file on another server from a web page

How do I read/write a text file on another server from a web page. I get the error "Access to the path '//Server2/mydatafiles/test.txt' is denied". I do not get the error if I am running the browser on the server where the files exist. I think I need to set permissions on the destination server in some way.   Can you help? Thanks  

Passing values from web page to custom security trimmer in SharePoint 2010

Hi, In SharePoint 2007 we had a custom security trimmer that implemented ISecurityTrimmer interface. We also had a custom webpart used for search. Now, using HttpContext we passed values from the webpart to security trimmer with additional info needed to trim the results. It worked since trimmer was executed in the same w3wp process as webpart. Now in SharePoint 2010, the architecture for ISecurityTrimmer2 has changed, as it's executed in search process (other w3wp) - not the webpart w3wp so it has no access to the HttpContext. Question is: how to pass custom data, in form of the string, to a security trimmer when search is done from custom code in webart?

Passing parameters from ASP.Net web page to SSRS report

I have a web page that displays some data.  The user first selects a date range on the web page and then can edit some data.  When they click a submit button, I want to run a report.  But I would like to pass the start date and end date values that the user already entered on the web page to the report.  Is this possible?  Can I use the value of a session variable in the report?

Problems passing parameters to SSRS report from ASP.Net web page

I have a web page that displays some data.   When they click a submit button, I want to run a report.  But I would like to pass the start year/month and end year/month values that the user already entered on the web page to the report.  Here is what my url looks like when the report is displayed: http://xyzserver/Reports/Pages/Report.aspx?ItemPath=%2fReports%2fDevicesAllNew&rs:Command=Render&StartYYMM=201007&EndYYMM=201008 But my report displays the 2 textboxes for my StartYYMM and EndYYMM parameters as empty.  What am I doing wrong?  I did a google search and I saw something about using ReportServer instead of ReportManager.  I notice at the top of the browser when I run my report, it reads "Report Manager - Windows Internet Explorer".  Is this correct?

Approval workflow is not passing task instructions to workflow task page (WrkTaskIP.aspx)

Hi, Very weird issue. Never happened before. I have Document Approval workflow, based on built-in approval workflow, which is available in document libraries of every site in the site collection. You might know that when you kick off approval (even collect feedback) workflow, you can enter task instructions, which will be passed on to the workflow task page (WrkTaskIP.aspx), and also included in the email, which will be sent to approvers (reviewers in case it is a collect feedback workflow). I know that the users used to enter task instructions, and before, it was appearing in the workflow task page where you approve/reject it. Recently, they noticed that the task instructions textbox was being empty, though the instructions were being entered when the workflow was started. Moreover, it stopped showing task instructions for other tasks that existed for a long time. BTW, this is not the same in every environment we have, but I could not find any difference in the settings when I compared them. Has anybody faced this problem? Please help if you know the solution. Thank you!!! Regards, R.D.M.

Passing a Text Value as DataView Filter Parameter

I have a dataview to which I would like to pass a text value for use as a filter.  My text value is on the same page within a DIV tag that I have given an ID.  When I view the page in the browser the text is actually rendered in a SPAN tag, within the DIV tag.  I have tried the ID for both the DIV and SPAN tags when setting up the parameter, and have tried using both a parameter type of Control and Form, but nothing I've tried is working. Any thoughts?  Thanks, Chanda
