Master Pages - Getting Error / Could Not Find Control 'TextBox1' In ControlParameter 'date_con'
Jun 3, 2010
I have a master page that divides the main content into two areas. There are two asp:ContentPlaceHolder controls in the body section of the master page with IDs cphMain and cphSideBar respectively.
One of the corresponding content pages has a control in cphMain that needs to refer to a control in cphSideBar. Specifically, a SqlDataSource in cphMain references a TextBox in cphSideBar to use as a parameter in the select command. When the content page loads the following run-time error occurs:
Could not find control 'TextBox1' in ControlParameter 'date_con'.
Description: An unhandled exception occurred during the execution of the current web request. review the stack trace for more information about the error and where it originated in the code.

I kinda know what the problem is... ASP.NET does not like the fact that the SqlDataSource and TextBox are in different asp:Content controls within the content page.
As a workaround, I have another TextBox in cphMain with the SqlDataSource which has Visible=False. Then in the Page_Load() event handler the contents of the TextBox in cphSideBar is copied into the contents of the non-visible TextBox in cphMain.
I am working on a project and I need to use Master/Details view, the problem is everything works fine except when I place the Master (gridview) and Details(FromView) in different content holder.
The error I get is:
Could not find control 'GridView1' in ControlParameter 'ID'.

I used this example from [URL] I changed it around to fit in a regular aspx page and it works great. however when I move it into my child page of a master page it fails on the AnimationExtended. Does anyone have a solution for the $find statement in child pages of a master page? Code is below. Errored line is bold faced.
I am trying to compile simple master page but i keep on getting following error.

I've seen similar posts but have been unable to resolve my error. When browsing the site from IIS I get the following error- a .master file does not exist. I can see it in the directory and everything works fine when running out of VS 2010.

I'm trying to find a TextBox in the code-behind page, it's inside a nested master page and also then inside another control container (it's inside ctrlCheckoutShippingAddress also) .
So all I want to do is simply find a user control I load based on a drop down selection. I have the user control added but now I'm trying to find the control so I can access a couple properties off of it and I can't find the control for the life of me. I'm actually doing all of this in the master page and there is no code in the default.aspx page itself.
MasterPage.aspx
[Code]....
MasterPage.cs
protected void goToSelectedPage(object sender, System.EventArgs e) { temp1 ct = this.Page.Master.LoadControl("temp1.ascx") as temp1; ct.ID = "TestMe"; this.UpdatePanel1.ContentTemplateContainer.Controls.Add(ct); } //This is where I CANNOT SEEM TO FIND THE CONTROL //////////////////////////////////////// protected void lnkSave_Click(object sender, System.EventArgs e) { UpdatePanel teest = this.FindControl("UpdatePanel1") as UpdatePanel; Control test2 = teest.ContentTemplateContainer.FindControl("ctl09") as Control; temp1 test3 = test2.FindControl("TestMe") as temp1; string maybe = test3.Col1TopTitle; }
Here I don't understand what it's telling me. for "par" I get "ctl09" and I have no idea how I am supposed to find this control. temp1.ascx.cs
I have an asp.net website with master pages. My controls got renamed from "myTextbox" to "ctl00_ContentPlaceHolder1_myTextbox"...and I have many javascripts that use that unique id...
HOWEVER, just suddenly (it used to work), my controls are now named (I can see this in viewsource) "ContentPlaceHolder1_myTextbox", so my javascript is all broken.
What caused this sudden change in naming convention?
I know javascript can utilize asp.net's ClientID property...but this is not working for me, cuz I need to be able to do "getElementById" and you can't use the client ID here.
I am using v3.0.31106.0 of the AjaxControlTookkit.dlll. I have nested master pages. The site Master page has the only ScriptManager & holds the oneColumn & twoColumn master pages. The twoColumn master page holds content pages. In the content page there is a update panel. Here is my Site Master Page:
[Code]....
Here is the Nested Master Page:
[Code]....
Before the update page I put the ToolkitScriptManager. In the update panel I put a button with a ConfirmBox Extender. I then get an error saying Only one instance of a ScriptManager can be added to the page. If I take the ToolkitScriptManager out this error goes away but then I get an error saying The ConfirmBox Extender is not recognized.According to all the posts I have read the last 24hours the master page should have the ScriptManager and the content page should hold the toolkitScriptManager.Here is my content page:
I am having a slight problem with adding text (output from a stored procedure) to a label control that is nested inside a contentplaceholder (ContentPlaceHolderProductsLeftCol). The page is also using master pages.
Below are excerts of the code - I think I would have to use teh findcontrol property however I am quite lost.
Label name is lastname and is located in ContentPlaceHolderProductsLeftCol
I've got a web site that has a master page and that master page (mpMaster that has a user control ucControl1) which has a sub user control (ucControl2), this user control has a property which accepts a value. Now, I have a page that uses the master page and on this page I have another user control (ucPageControl), I need to find a way of setting the value in ucControl2 from ucPageControl. Is this possible at all?
I am trying to do a version of this post, but with the EntityDataSource. I think I am close, but it seems that the "InsertText" and "Insert" command in the code-behind do not carry over. Here is what I have so far, but please help me fix it. In addition, in the .edmx the Table "UserProfiles" inherits from "aspnet_Users"
I have a control on a master page called "panel1". I would like to access it from my Javascript on the content page. I have tried var panel1 = document.getElementById('<%= panel1 %>'); It doesn't work since it is on the Master page.
Im using ASP.NET 2.0 with C# for website development. I have created two master page Base.master and web.master.web.master refer to base.master as its master page. Base.master contains head(specified various CSS links) and body(some general controls and hyperlinks to other websites).Now i create test.aspx with web.master as its master..Now I try to implement ajaxtoolkit:calendarextender which initially gave me error that head tag should have runat="server"..This error got resolved but i lost CSS of my website and also calendarextender doesnt work. calendarextender works fine if I dont refer my master page.
I don't loose my CSS and calendarextender should work as normal.refer text.aspx
