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

Posted By:      Posted Date: September 05, 2010    Points: 0   Category :ASP.Net
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

CSS Problem on ASPX page


I am having a problem with space around a div. The page looks perfect in the VS internal browser, but there is space at the top between the body and the div for the page layout in IE and FireFox. I tried everything I know by setting margins to 0 and padding to 0 for the body, div, form, almost everything and there is still space. The wierd thing is that the space shows the background color when I set the padding for the div#page to 0, and the space is the div#page background color when the padding is set to a value.

I must be missing something. I looked at the page's HTML after it is rendered from the server and it inserts a dive with a hidden control for the viewstate. I thought this might be causing the problem so I set the margin and padding for all divs to 0, but it did nothing.

The code for the simple page and CSS is provided below.

It appears the problem disappears and the page looks as I intended when I use the Compatibility View in IE8.

Thanks for the help in advance,
-- Chris

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.

Correct Way to Insert Data from Text Boxes on ASPX page into SQL Database Using VB


Please help me, I have been trying this for a week now and this is how far I have gotten.


I am new to this, and I am using MS Visual Web Developer Express.


OK - This is what I have come up with, but when I run it I get the following error  (I decided to just try to use a simplified table just to get an understanding of the basic concepts):



Partial Class label_form
    Inherits System.Web.UI.Page

    Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
        ' Declaring variables
        Dim username, labelname, ownersname, address1, address2, city, state, zipcode, country, contactnumber, emailaddress, data_source, con, sql_insert

        ' Check if Necessary Text Is Missing ( will do this once I can get it to work with no empty text boxes)

        ' Get Values from TextBoxes
        username = txtUserName.Text
        labelname = txtLabelName.Text
        ownersname = txtOwnersName

Edit.aspx page hanging on text entry


I am trying convert a project from asp classic to asp.net.  The asp classic version has a edit table page that allows users to enter data into textfields that contain html mark up.  like <b>, <i>, etc.  I have been working with the dynamic data video collection and when I try to hit update after entering any html markup in a textfield, in edit.aspx, the page just stops.  It does not throw an error nor does not redirect to the list.aspx on update or cancel, and im pulling my hair out trying to figure out why its doing this.  I have tested various different data types and nothing is helping.  Anyone have any ideas?  The error happens on the sample code provided on the dynamic data page.

Launch CMD File From ASPX Page


My organization uses a CMD file to install updated files for a major enterprise application. Currently, we send out an email to users with a link to the file and instructions to run it, BUT inevitably users don't update their machines until their in field and try to start the app.


We're now liking the idea of using an ASPX page to prompt the users to run the updates and to capture the fact that the updates have been run. I realize that we can't capture the success or failure of the update. But we'd like to capture the user accessed the page.


Is it possible to embed into the markup for the page a link to the file on the local intranet that the users can click on to run the file?

The user accessing the page would capture that they did just that. We'd deal with wether or not the update was actually installed or if it failed later with them directly.

Visual Studio closes itself by opening aspx-Page designer after Windows Update


Hey Guys,

I've a problem with my Visual Studio.

On the 13th of August 2010 i installed a Windows update on my vista sp2 pc. For this date my Visual Studio 2008 sp 1 always has closed itself by opening an aspx-page in designer view. There is no error message just closing the window. I restored a backup of my windows from the time before updating it and it helped, i could open aspx pages in the design view till the update has been installed again automatically after rebooting the pc. I can't disable windows updates, cause it's my pc at work and safety is very important. I hope you could help me out of this disaster.

Flash player doesn't send cookies while requesting an aspx page



 I'm developing a web-site, that uses SWFUpload for multiple files upload to the server. Page, that uploades files, is accessable only to registered user. Authentication is done via web-forms (authentication mode="Forms" in Web.config). Flash uploades files to special web page - upload.aspx. In IE everything works great, but Flash player in non-IE browser (in Firefox, for example) does not send any cookies to upload.aspx. Because of it no sesion and no authentication information is available in this page.

 I can pass all the information, necessary for uploading, in GET-parameters, which upload.aspx recieve. But this is a serious security hole and I don't want to expose session information. I can pass session identifier in GET-request. But the question is the following: how can I restore session information from the session identifier? How can I make HttpContext.Current.User point to currently logged in user in this case?

Any help will be appreciated.

User Control not accessing the value of the properties send to it from the aspx page.


I have a dynamic accordion on a page. Set its datasource to an object of paged data source.The user control is in the accordions content template. When i was writing code the properties were showing but after giving the values of databases as


<uc:UserControl1  runat="server" Property1='<%#DataBinder.Eval(Container.DataItem,"columname1")%>' Property2='<%#DataBinder.Eval(Container.DataItem,"columname2")%>'  ></uc:UserControl1>


but the values shows null, these properties are shown as textboxes text property by user control.

MoreOver when I checked the values of database Items.So i made a textbox instead of usercontrol here as

<asp:TextBox ID="txtTest" runat="server" Text='<%#DataBinder.Eval(Container.DataItem,"Columname1")%>'></asp:TextBox>

It is showing the correct value. And if i pass the value directly it is also showing correctly like

<uc:UserControl1  runat="server" Property1="XYZ")%>' Property2="ABC")%>'  ></uc:UserControl1>

. where I am wrong

the problem is eval is not passing the value to usercont

Way of showing ID on the DispForm.aspx page without programming?

Is there a way of showing the ID system field on the DispForm.aspx page without programming.
I don't want to use a dataview, as new fields being added in the future won't appear automatically anymore this way on the DispForm.aspx page. 

I found somewhere that I could use a calculated field, with as formula =ID (so, in fact just copying the value of the ID field in the calculated field), which is one option.

Are there other options/solutions known?
