Strange Problem With Asp.net ... Tabpanel / Gridview Moving Out Of Table Area?
Feb 28, 2011
I am facing a strange issue with my project ... when page is rendering my tabpanel/gridview is moving out of table area. To brief: I have declared a tabpanel inside table like
But still Iam facing the same issue. Gridview rendering is moving out of the table width. I tried changing the table width and Gridview width but no luck.
It's even not the problem with CSS design ... cause Gridview in other pages are working fine.
I have a TabContainer with 3 TabPanels. The container has a yellow background. On the first tab the yellow background is the height of all the controls. On tab 2 and tab 3 I just get a strip of yellow and then below that is my table of controls. The controls are outside of the TabPanel border. I checked the code and my table on each tab is between the <ContentTemplate> tags. This was not doing this before. This app is VS 2005 with Ajax Version=1.0.61025.0 All I have changed is installing VS 2010. I even took an old backup and it's still doing the strip of yellow on tab 2 and tab 3. Here is my stylesheet:
i have a tabcontainer which have 3 tab panels(tbpanel1,tbpanel2,tbpanel3)and i have dropdownlist in each tabpanel to select date(with autopost back=True).so if i select the date from tab panel2 or tabpanel 3 it is automatically going to tabpanel 1.but it should be in the same tabpanel.
I used ModalPopup Control on this link, [URL]How should I write the code that to close pop up by click the area outside the pop up panel?I use AjaxControlToolkit-Framework3.5SP1
I'm maintaining a dynamically generated table in ASP.NET, which allows users to move items up and down in the table. What this essentially does behind the scenes is just swaps around the 'sortorder' which the table is sorted by. I have checks to see if a row is the first/last column, and if so only display up/down (whatever's relevant). An issue has crept up now and I have no idea why. For some reason, most of the time (not all of the time strangely) the up and down buttons don't work. Using 'Up' as an example, the current record does get set to the 'above' rows sortorder, but the 'above' row doesn't take the below rows sort order. Now I've set my breakpoints throughout my code, and strangely everything gets set fine. It's just when I call SubmitChanges() to the LINQ data context, that it seems to put the wrong value into the database. Also what's strange is that I think that if you click it again, it actually works. But it doesn't work properly as the number is still out by a bit.
Here's my code: if (Request.QueryString["dir"] != null) { if (Request.QueryString["dir"] == "up") { var currentrecordup = (from s in dc.InvoiceItems where Request.QueryString["val"] == s.id.ToString() select s).Single(); int valsortidup = (int)currentrecordup.sortorder; var prevrecordup = (from s in dc.InvoiceItems where s.sortorder < valsortidup orderby s.sortorder descending select s).First(); int prevsortidup = (int)prevrecordup.sortorder; int tempval = valsortidup; currentrecordup.sortorder = prevsortidup; prevrecordup.sortorder = tempval; } else if (Request.QueryString["dir"] == "down") { var currentrecorddown = (from s in dc.InvoiceItems where Request.QueryString["val"] == s.id.ToString() select s).Single(); int valsortiddown = (int)currentrecorddown.sortorder; var nextrecorddown = (from s in dc.InvoiceItems where s.sortorder > valsortiddown orderby s.sortorder ascending select s).First(); int nextsortiddown = (int)nextrecorddown.sortorder; int tempvaldown = valsortiddown; currentrecorddown.sortorder = nextsortiddown; nextrecorddown.sortorder = tempvaldown;} dc.SubmitChanges(); Response.Redirect("EditInvoice.aspx?id=" + Request.QueryString["id"]); } The sortorder column in my table is an int field that allows nulls.
I created a ASP.NET project under Visual Web Developer 2008. Under that project I had a Database (along with ASPNETDB.MDF) which has about 3/4 tables (I had SQL server 2008). Everything was working fine (like insert, delete, etc.). And I was able to view the tables in database explorer view.
Then I had to format my computer for some reason and I copied the whole project in a USB drive and then after formatting the computer I copied the folder and tried to open it in Visual Web Developer (now I have VWD 2010). I can see the both Database under App_Data folder (ASPNETDB.mdf and the DB I created). ASPNETDB has all the tables and data as expected. But I do not see the tables under the DB I created.
I've got a user control that is displayed via a PopupControlExtender. The user control is a GridView that dynamically adds columns to the control to display the results of a SELECT statement. The PopupControlExtender correctly displays the control and the control displays the neccessary columns. However, when the control is first displayed, the column widths are ignored, despite that they are explicity set. If the control is displayed and then hidden, the column widths are acknowledged the next time the control is displayed.
I have strange behavior when changing from ItemTemplate to EditItemTemplate. both the ItemTemplate and EditItemTemplate contain the same textbox with multiline. Except the ItemTemplate got the ReadOnly parameter. When the row is getting in EditMode and I enter the textbox everything is disabled. I click on another column that contains a label instead of a multiline textbox and get back in the textbox I can do everything. When I enter in the same row another MultiLine textbox I cannot do anything until I click on a label and get back in that TextBox. When the textboxes are in normal mode I don't seem to be having this issues. What is changed between the MultiLine and SingleLine textbox? What kind of PostBack or something could cause this strange behavior?
I have a asp:button in template field of gridview, I set command name for this and in grid I mention on command event. On clicking the page it shows error message is :Invalid postback or callback argument. Event validation is enabled using <pages enableEventValidation="true"/>
I'm having a strange problem - probably has a simple answer but, I haven't been able to find it or figure out the cause. I'm hoping someone has had this same problem and figured it out.
Basically - my application works great on the development machine. So I copy it over to the server and it works great. Come back the next day and my GridView is only displaying the first record...I then log into the server remotely and open the web page on the server and all records are returned, so the application works fine on the server. I then return to the local machine and now the application is returning all rows in the GridView. So, weird but, what whatever, it works. Go away and come back again the next day and...
1 ) Only 1 record from dataset is displayed in GridView
2 ) Log onto server remotely and view webpage on server --> all records now display
3 ) Try again on local machine, now application works fine...grr. What am I doing wrong here? Using Visual Web Developer 2008 on Windows XP. Querying SQL Server 2000 (I know, I should switch to 2005 and use VWD 2010 - but ouch, really!) when a text box value changes (Vendor_PO_TextBox.TextChanged)
I have a gridview with Action button. When this button is clicked Javascript Confirm Popup will Display, after click on OK the Event have to fire GridviewRowCommand but the strange thing is: when the button is clicked, the rowcommand method is NOT fired! When I place the code on a separate page the event is fired, but when placed inside the tabcontainer for some reason it isnt...
I have an ASP.net gridview on a webform where user's can select a row. When they select it, the row is highlighted yellow. The problem is that when I sort the table, it sorts properly but the highlight stays on the same line. The data all moves, but the highlight stays put.
I created a GridView in code with a DataTable as its data source which worked fine. I have now moved the GridView creation into a .ascx file to make it easier to format.
For some reason this has started triggering the HttpParseException: Databinding expressions are only supported on objects that have a DataBinding event. System.Web.UI.WebControls.HyperLinkField Original code: // Set up columns for datagrid var boundField = new HyperLinkField [code]...
we need to move Gridview rows up or down by selecting the same.
we have two buttons as up and down.
After selecting a row(index(X)) then if we click up the row(index(X-1)) will come down and row we selected will move up.
same case with the down button ,After selecting a row(index(X)) then if we click up the row(index(X+1)) will come up and row we selected will move down.
all these changes has to reflect on database(order of records stored) also.

I've got extremely strange behavior on one of my pages. I was able to get a work-around in place, but I'd like to get input on why this error is happening (and why my work-around actually works).
(Let me also say that this is in no way, shape, or form my code...so please don't bash me too hard)
When loading the page, we're getting

I am using pdf4net to export PDF file. In C# I created complete logic to export data. A large part of it is legacy code so I know for sure that it works. But there is one little problem. Error in the end of code. Everything before that line is fine I check it several times. Bellow is the last line in code and bellow it is error that I receive after that line:

Recently I started a project and added a HTML file in it. I modified the HTML file and run it in Visual Studio to see the output. When I tried to validate the HTML file, I found some strange characters got appended. This is quite annoying, although I am not able to see those unexpected characters, I wonder what is the cause of the problem. I didn't adjust anything in control panel of the IIS server, I didn't modify the Web.config file. I tried to add another HTML file and put the same content into it, the same problem occured. Could someone tell me how should I troubleshoot the problem?
using vb.net/asp.net 2005 and sql server 2005. I'm querying the database and returning text which I am then adding to a string. I'm creating a crystal report with the text however this is not a crystal report question, its about the string data. what I"m noticing is that when I show the string on the pdf that there are some strange characters at the end of the string. I am both trimming the string and taking out null characters however the strange text shows up like this:
strangeText> SÙÇ TÙçy|Ü DÙÇ $ÛÇ </strangeText>
does anyone know what these characters are and how to get rid of them?
I have this strange error coming up in VS2008, where is says a variable in not declared in HTML view, when it clearly is declared in the codebehind:Can anyone help with why this might be happening? I've tried all sorts of things, even recreating the page from scratch, but this keeps coming up.
