At runtime I would like to be able to change the ascx to another path, it would still be inheriting from the same usercontrol codebehind, it would just be a different template.
I want to add and use the user control at runtime in the master page.
I have used LoadControl Method to add usercontrol but in that case i was unable in getting the tagprefix and tagname value of the user control so that i can use it on master page file also.
I was wondering if it is possible to upload the .ascx and .ascx.vb of a custom usercontrol into my project directory at runtime via an upload control and then after that use through a database query point my page to load that newly uploaded control via (LoadControl(<newlyUploadedControl>)?
If I press F5 (IE) after user control was rendered, I get IE's warning window that IE needs to resend the information.... How can I prevent it and why does it happen?
UPDATE:Maybe there is another approach? I want to load specific control (with it's markup) when user selects it from the dropdownlist. if a postback is made the control shouldn't disappear(only if another control was selected from the dropdownlist) Everything is inside update panel!
We're having an issue with a .NET 3.5 WebForms site where occasionally our error logs start filling up with the following error message:
"Multiple controls with the same ID 'ctl09' were found. FindControl requires that controls have unique IDs."
I know very little about the exception as I have never seen it while debugging locally and have never caught it in the error logs soon enough to run a remote debugging session. I do know that an application pool recycle fixes the issue.
This only affects a single [high traffic] page in the site. The strange thing is that the site uses the pre-4.0 ID generation logic. So, when the page is working, there isn't an html element in the entire view source that isn't some autogenerated control ID prefix followed by a the 'actual' IDs (i.e. ctl09_someID_someOtherID).
What would case a control to randomly stop being built correctly? Other than the Global.asax, how can I trap this error and force the control to ... recompile? App pool to recycle?
I'm trying to make a template control using UserControl. I have two issues: When I use the template it only show the Body text - not the Title text - why?. And I don't know how to implement styling (css) - can you tell me how to use a custom css file (Container.css) in .the App_Themes folder?
How would I do visual editing of a template for a control X that is embedded within a user control?. Of course, in this case the Control X is not directly available to the end user.
NOTE: I do not want to create another user control to the template.
I've an item template inside a grid which has a <asp:LinkButton/> inside it. I assign the text for the link button as
<%# Convert.ToString(Eval("Tags"))%>
Tags can have a string with multiple tags in it delimited by space. For eg. "sports", "sports cricket", "sports cricket sachin" are the examples of some possible tags.
I want to create a button for each tag inside the string. How can i create the controls (server control - linkbutton) dynamically during runtime inside the grid item template?

there's a label control on my master page..if its value is "Value1" ,I want this CSS Sprite to display on my webform..if the Value is "Value2"..the CSS sprite should use some different image..just the image needs to be changed ..nothing else in that Sprite..
I found out that I can use "FindControl" method to find out what value that Label Control of Master Page's currently got..
Now how do I change that image on the banner ?? How do I go about it ? Also that CSS Sprite now is a user control named "myBanner.ascx"(earlier was an aspx file)..Now do I need to make 2 diff usercontrols or I can implement some logic in one usercontrol itself ?
Should I make 2 copies of this "myBanner.ascx" with JUST the "image name" changed in its CSS ???
Hope its not confusing..Actually I am lost :/
What I want is ONE banner which has been made using CSS Sprite ..Now if the "Label Control's "value in the master page is "Value1" then the image to be used on that banner is "IMAGE1" else if "Label Control's" value is "Value2" then "IMAGE2" should be used in that sprite..
In my website1, I posted some data to my website2 by doing an HttpWebRequest.The data are posted successfully but what I wanna do is change the imageUrl in website2 after website1 fired some data. When I try to debug, I can see that it passes through the code of changing the ImageUrl, but when I view the source of website2, I can't see the imageUrl being change at all... Does anyone have a clue?

I'm filling a previously created DataGridView on an ASP.NET Web Form dynamically with a DataTable, but I want to change the name of the columns that appear on that DataGridView, and I simply can't figure out what I'm doing wrong. Below is the code:
DataTable dtUsuarios = DBManager.RunSqlGetDataTable( @"select b.UserName, c.Email, c.IsLockedOut, c.LastLoginDate, case when e.RoleName is not null then 1 else 0 end Admin from dbo.aspnet_Applications a join dbo.aspnet_Users b on a.ApplicationId = b.ApplicationId join dbo.aspnet_Membership c on b.ApplicationId = c.ApplicationId and b.UserId = c.UserId left join dbo.aspnet_UsersInRoles d on d.UserId = b.UserId left join dbo.aspnet_Roles e on d.RoleId = e.RoleId where a.ApplicationName = 'Mont Blanc Catalogo'"); dtUsuarios.Columns["UserName"].Caption = "Nome Usuário"; dtUsuarios.Columns["Email"].Caption = "E-mail"; dtUsuarios.Columns["IsLockedOut"].Caption = "Bloqueado"; dtUsuarios.Columns["LastLoginDate"].Caption = "Último Login"; dtUsuarios.Columns["Admin"].Caption = "Administrador"; DataView dvUsuarios = new DataView(dtUsuarios) { Sort = "UserName" }; gdvUsuarios.DataSource = dvUsuarios; gdvUsuarios.DataBind(); //gdvUsuarios.Columns[0].HeaderText = "Nome Usuário"; //gdvUsuarios.Columns[1].HeaderText = "E-mail"; //gdvUsuarios.Columns[2].HeaderText = "Bloqueado"; //gdvUsuarios.Columns[3].HeaderText = "Último Login"; //gdvUsuarios.Columns[4].HeaderText = "Administrador";
Setting the values changing the caption of the DataTable doesn't work, and after the DataBind, the Columns.Count property for the DataGridView return zero columns! After executing the code, everything appears normally at my asp page, but the captions are wrong.
I have tabs in a page. Each tab has a background image of fixed length. So when the text for the tab is bigger("arrangement help"), it displays "arrangement" in one line and "help" underneath. My goal is to display arrangement and help in one line. Tabs have to customizable.I am using css for regular tabs.
#tabs a { float:left; background:url("../images/selection_deselect_bg.jpg") no-repeat right top; margin:0; text-decoration:none; width:105px; text-align:center; height:24px; font-size:12px; color:#00779c; font-weight:bold; text-decoration:none; }.
I have an bigger image and i am able to get the size of the text in tab. But how to use bigger image for the tab? How to use change background on runtime.

Protected Sub gvCriticalMaterials_RowCreated(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles gvCriticalMaterials.RowCreated If e.Row.RowType = DataControlRowType.DataRow Then If Trim(e.Row.Cells(7).Text) <> "" And Trim(e.Row.Cells(10).Text) <> "" Then If Convert.ToDateTime(e.Row.Cells(7).Text) < Convert.ToDateTime(e.Row.Cells(10).Text) Then e.Row.Cells(7).ForeColor = Drawing.Color.Red End If End If End If End Sub
But it never shows any value for text in the cells.
