Need Debugging Hints: Visibility Change On Postback Works On One Page But Not Another?
Sep 26, 2010
I have a webform containing a user control. On that user control is a set of radio buttons. When the radio button is changed, a panel and a text box is shown or hidden depending on which radio button was selected.I can give you an example that works correctly:testcontrol.aspx:
I'm finishing up my first web service. It stores data on a dataset that I later need to check up on, so I need to keep that information around. I've already enabled the session in the web service's method "EnableSession = true" [WebMethod(Description = "Receives status requests, as well as status udpates.", EnableSession = true)]
If I debug the web service everything works but if I try to use the application that sends the requests to the web service while it is published, the session keeps restarting again and again and again.
I have a gridview with some data and two hyperlinkfields.I want to make the first hyperlinkfield of the first row not visible and the second hyperlinkfield of the last row not visible.this what I did till now
Protected Sub GridView1_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles GridView1.RowDataBound If e.Row.RowType = DataControlRowType.DataRow Then[code]....
This will work only for the first hyperlinkfield.Omitting the comments will make the first hyperlinkfield not visible for all rows.
I want to change controls visibility on c#, but nothing happens. The controls are in an AspxPopupControl and 3 of them are hidden in design time, 1 of them is visible. I use this code to visible them
It renders Fine with Register symbol after the text "My Test Application Name" on start of the page but on any postback the title turn into My Test Application Name® Kindly let me know what can i do with minimal effort to fix this issue
aspects of some controls in Code Behind (VB) with controls inside a datalist and/or repeater. I have read a lot of stuff on using some tricks but none seem to work so far. I am new to ASP.net so some of the explanations are too cryptic as well. Below is a section of code that I am trying to change. This example is attempting to make the label visible if the dataitem is true and hidden if false. No matter what I seem to do I cann't reference this label to change. I also want to change the text on some other controls in this dataitem if the returned value is a certain value.
I have developed my application using Visual Web Developer 2008 express with Visual Basic code.
If I am working with 2 textboxs on a form, and I set the "Autopostback" to "true" for the first texbox then on the "changed" event, I can just add code to set the visibility to "true or "false" for the second textbox - it works fine. However, I do not seem to be able to figure out how to do the same thing when I am using a Dataview.
I have a table called "Customer" that contains 4 fields "CustomerName", "BasePrice", "LevelOfActivity", and "Discount".
My user enters information into this table using a Dataview form that displays the 4 fields.
When the user enters the value "L" in the field "LevelOfActivity", I would like to then set the visibility of the field "Discount" to "false" - (I want to hide the field as this customer should not get a discount). If the user enters the value "H" in the field "LevelOfActivity", I would like to then set the visibility of the field "Discount" to "true" - (I want to show the field so the user can enter the "Discount").
I have  Table  named   PRODUCTS , that have 4  column  productid, productprice,productname & discount( type  numeric(18,0)) .. i am using datalist with itemtemplate that have  4  label to display all ..
I am binding datalist on pageload, now i want that Label4 Â with "discount" should only visible for those product that have discount , otherwise it remains hidden,Â
Problem in my code is that when i run it , label becomes invisible for all  products whether they have discount or not. Here is my code i am using for it:
ds1 Â is my datasetÂ
 foreach (DataListItem item in DataList1.Items) {               for (int i = 0; i <= ds1.Rows.Count - 1; i++) {                 double[] arr = new double[ds1.Rows.Count];                 double temp = double.Parse(ds1.Rows[i]["discount"].ToString());                 arr[i] = temp;                 Label lbl = item.FindControl("Label4") as Label;                  if (arr[i] == 0)                   lbl.Visible=false;               }  }
I have an asp.net page with couple of div elements on my page. Some of them are floating left and some are separated with <br /> elements.When I put a button which just post-backs and click that, I see that some divs (which were floated to left before) are repositioned to a new line
How to change visibilty of panel based on imagebutton mouseover and mouseout here, i have panel1(Panel) and btnimg2(imagebutton) i want to show(Panel1.visibility=true) when mouseover happens on imagebutton and Panel1.visibility=false when mouseout on imagebutton
I have a page with two columns. Initially, the left column will contain a list of links that are article titles. Clicking on one of the links will display the text of the article in the right column, keeping the list of titles in the left column. Clicking on another title will clear the text of the first article and display the second. Is there a way to accomplish this without having to repaint the whole page? I would rather not have the whole page resent each time a title is clicked, but rather have the page stay as is and only the contents of the right column get cleared and redisplayed. I assume there's a way to do this with JavaScript.
I have a details view with buttons in the footer. When the user clicks the edit button the calls the ChangeEditMode() method. I want to change the mode of the details view to edit mode which seems to work fine. It goes into edit mode with a text box. I also want it to set the visible property of the edit button to false and set the visible property of the update button to true. Then while still in edit mode the user can click the update button that will call the appropriate method to persist the changes.
I got the changemode() to change to edit but can't change the visible property of the buttons correctly. This is what I have so far. Can some one please tell me what I'm doing wrong?
I am using datalist and used custom paging for that but on page index changed there is full postback..because i am sending the values through querystring just have a look to this link
1) i have a image control on a page which is supposed to send url parameters to a url on a different server once it is clicked..
2) when i click it, it fires an event which uses the form parameters to build a url then this assigned to the postbackurl property of the image control.
3) After this first click the page is not redirected but if you click it a SECOND time, it goes to the appropriate URL.
why this is happening and what i can do to ensure it gets redirected after the FIRST click?
I am trying to figure out why javascript functions I create with declared return types are not giving me intellisense hints. See code below, specifically updateNextItemTime in Sample.TodoList.
I'm trying to change the visibility of a imagebutton to false, if the imagebutton.ImageUrl="". The problem is that the imagebutton is inside "ListView2", and "ListView2" is inside "ListView1". Who can I do this in vb code... or even a javascript.
I'm using what I believe is a pretty common/boring/generic implementation of a ModalPopupExtender. I'm using client-side JS to show the dialog when the user clicks a link, and hide it if they click "cancel". I only do a postback if they truly want to save the data.
I can click the link to show the dialog, then click the cancel button to hide it, then click the link to show it... ad infinitum. If I decide to save the data via a postback, everything works well, and the dialog is hidden as a result of the postback, all as expected.
However, once the postback completes, my client-side JS show() never works again. Any attempts to click the link fail quietly; no error messages, the dialog just never shows again.
I am working with a formview edititemtemplate. Currently in my page load, i have some stuff that would show or hide certain panels based on dropdownlist values. These dropdown values get binded during page load. I need to be able to change the values/dropdowns, without rebinding the old data, and updating the visibility of the panels based on predefined rules.
I have experimented with putting my formview.databind() in page load if isnotpostback, in prerender, in prerender if isnotpostback. I have tried my rules (ex if ddlState.selectedvalue = "DE" then pnlDelaware.visible = "true") in the page load, and the page render. I'm just not sure how to get the stars aligned here. The closest i have come is having the databind in the pageload if notispostback, and the rules in the prerender. However I get an error "dropdownlist has a SelectedValue which is invalid because it does not exist in the list of items.
I have a web page where a div needs to be displayed under certain conditions. I'm using the following code to toggle the display and have verified that it works.
[Code]....
To call this javascript function, I'm using the following code in the code-behind for the page:
[Code]....
I traced the flow using the debugger. When the page load, txt_Cat_ID.Text = "2" correctly resolves to FALSE and the toggleOptionsDiv script is run with the 'hide' parameter. The page correctly hides the div.
When I click on the link that makes txt_CAT_ID.Text = "2" resolve to TRUE, the code executes the line where the toggleOptionsDiv script is run with the 'show' parameter. However, the div remains hidden.
The link that is clicked triggers an asynchronous post back and I'm not sure if that is the problem. How can I get the div to display on postback?
I am building a website in which all of the site layout is in Master page and the content of the site is in the inherited pages. I have various links for navigation in which i simple use Response.Redirect to transfer to different pages. Now the problem is that I want to put the content place holder inside Ajax Update panel so that the postbacks are Asynchronous and I want to show the postback by an animated image inside Update Panel progress control. The problem is that I am unable to achieve this result and the entire page is posted back and rendered again. I have placed the content place holder inside the Ajax control toolkit's Update panel but it does not work. Is there any way that I can change the content of the content place holder to a new page with asynchronous postback.
