I have to use inline code for an aspx page and I need to use a custom server control that is defined in the same aspx page but the control does not get processed as a server control. it gets returned as is as static html tag.
View 3 RepliesI want to write own control which can contain other. And I want to define content of the control in the .aspx file where the control is defined. I have written such control. But now I have issue with ViewState of inner controls of my control. The following samle illustrates the issue: I defined two asp:DropDownList ID="ddl1" and ID="ddl2" One of them is inside of my control and other is outside. When posback is occurred asp:DropDownList ID="ddl1 loses state and becomes empty. How to say ASP.net to store state of inner controls defined by this way?

I am creating a custom server control, and I am wanting to include a JavaScript file in the dll file when the control is built. I have tried suggestions from the following websites:[URL] But after following the directions, If I use firebug to see what errors show up, the JavaScript functions that are being called all say "goNext is not defined" which leads me to believe the JavaScript file is not being added correctly.
Some information on what my control looks like
I have the JavaScript File in a folder called Script. The namespace of the project is CustomControl, and the Name of the project is MaskedDateTextbox.
In my AssemblyInfo I have the following:
<Assembly: AssemblyVersion("1.0.*")>
I'm having a dumb problem that is killing me. I have created the simpelest custom server control in VS 2008 c# called MyMsgBox. On the ASP page I put it in and register it. But, in the .cs file, when I try to call one of its functions I get the compile error that it is not found. The funny thing is that intellesense has it in the list and all of the functions with their given arguements. At the top of the .cs file I am using the namespace. The code for the custom server control is in the App_Code folder.
Also when I remove all refrences to its functions, the code compiles and when debugging the constructor for the class MyMsgBox gets hit.
<%@ Register TagPrefix="cc1" Namespace="CustomServerControls" %>
...
<cc1:MyMsgBox ID="msgBox1" runat="server" />
Task.aspx.cs
...
Using CustomServerControls;

this.msgBox1.confirm("Would You Like to add a new Task for this PO/Contract? ", "hid_f"); Error Message: 'Tasks' does not contain a definition for 'msgBox1' and no extension method 'msgBox1' accepting a first argument of type 'Tasks' could be found (are you missing a using directive or an assembly reference?)

View 1 RepliesI am in the process of adding my custom aspx pages to the LAYOUTS folder(a folder I created) in a WSPbuilder solution in VS08. The problem I am having is when I build the solution it fails because the controls(Load, Textboxes, dropdown lists,etc) in the code behind file for the custom aspx pages say they are not defined. They all have a blue squiggly line and I get over 100 errors.what to do to get the WSP to recognize the code behind pages.

I am working solo on an Asp.net/C# project created by someone in the past. I created two new web forms, and then built the prjocect and did the deploy using a TFS team build project. For some strange reason, my Aspx file is not getting copied to the destination DEV server. It does get copied to a temp folder on that server, but in the end, the team build is failing and not copying over the new Aspx file.
So until I figure out how to fix the team build script, is their a way to just copy the Aspx file out to the desired server location? That as well as copying out a dll which is associated with the build file?
I'm building this small control. It should detect client resolution and set height and width values within two separated HtmlInputHidden controls. But tester property is not getting values froms this control.

I work in VS 2008. Whenver I add a server control(Label) and set it properties in aspx.vb and build the solution, I get the error "Label1 not declared". While analyzing this issue I noticed that the event handler statements for the Label1 where not added in the designer.asp.vb file. These statement would actually be added automatically when I drag and drop a control to my webpage.
I would also like to inform the scenario after which this problem came to me. I was working in VS 2008 , VS 2005 and VS 2003 in the same machine.Could this have caused the issue ?
Now each and everytime when I add a control, I am adding the "With Events" code in the designer page to make my build succesfull which makes me to spend more efforts.
I have a page with a Textbox, a Button and a Label control. On Button_Click event , I store the value of Textbox in a variable called S using code behind.
I want to show the value of S in the Lable control using inline code but not using the code behind. ?
If the answer to this question exists somewhere, I'm no good at searching for it. This is sort of a simple question, the response being two parts: (1) is it possible? (2) if so, how?
I've created a web user control for my site's footer. In my web.config I have it registered like this:
[Code]....
Then, within the pages on my site, I simply insert it like this:
[Code]....
But obviously, that didn't work. I get this error: The type or namespace name 'FooterControl' could not be found (are you missing a using directive or an assembly reference?)
So I'm really not sure what to do at this point. I can put all of my code in the ASPX file and make my life easier, but I would kind of prefer not to.

I have developed a User Control in inline code model and convert this into dll and try to add it into Visual Studio ToolBox. It shows error "There is no component found in the object.". It is showing actually because i have not added ToolBoxData attribute just before the class declaration, because there is no class declaration in the inline code model. I don't know where i have to add ToolBoxData attribute.
View 1 RepliesI have a custom control that is based off the gridview control located at: here The control is basically a gridview that automatically creates a column of checkboxes that can be used to "check" individual rows in the gridview. During the gridview's "CreateColumns" event, the "checkboxcolumn" is created dynamically. The checkboxcolumn also contains another checkbox in the header that is used to "select/deselect all" checkboxes in the column. Since the gridview does not automatically remember the state of the checkboxes in the checkboxcolumn on postback, I added a method to the control called "SaveCheckBoxState" which stores the indexes of the checked rows in Viewstate, and then I modified the "OnRowDataBound" event to check the Viewstate and reset the checkboxes based on the Viewstate.
I then added a call to "SaveCheckBoxState" in the gridview's OnSorting and OnPageIndexChanging events. This works great so long as I'm sorting or changing pages. However, I need it to update the viewstate everytime someone clicks or unclicks one of the checkboxes. At this time, the checkboxes are rendered with an onclick event that calls some javascript to highlight the row, or in the case of the checkbox in the header, to select/deselect all checkboxes. I need to call the "SaveCheckBoxState" method from the javascript used by the customcontrol, or I need to find a way to modify viewstate from javascript and perform the same action as "SaveCheckBoxState".
I've tried adding the "SaveCheckBoxState" to the onclick event declaration in the checkboxes, but when run, it simply tells me that the method is undefined. It doesn't exist in the parent page, and I don't think I should have to make an event for the parent page to pass the click to. It seems to me this should be all self contained within the custom control. Does anyone know how I can acheive this? Here is the code for the gridview OnPreRender event where the onclick event of the checkbox is set:
protected override void OnPreRender(EventArgs e)
{
// Do as usual
base.OnPreRender(e);
// Adjust each data row
foreach (GridViewRow r in Rows)
{
// Get the appropriate style object for the row
TableItemStyle style = GetRowStyleFromState(r.RowState);
// Retrieve the reference to the checkbox
CheckBox cb = (CheckBox)r.FindControl(InputCheckBoxField.CheckBoxID);
// Build the ID of the checkbox in the header
string headerCheckBoxID = String.Format(CheckBoxColumHeaderID, ClientID);
// Add script code to enable selection
cb.Attributes["onclick"] = String.Format("ApplyStyle(this, '{0}', '{1}', '{2}')",
SelectedRowStyle.CssClass,
style.CssClass,
headerCheckBoxID);
// Update the style of the checkbox if checked
if (cb.Checked)
{
r.BackColor = SelectedRowStyle.BackColor;
r.ForeColor = SelectedRowStyle.ForeColor;
r.Font.Bold = SelectedRowStyle.Font.Bold;
}
else
{
r.BackColor = style.BackColor;
r.ForeColor = style.ForeColor;
r.Font.Bold = style.Font.Bold;
}
}
}

I have a custom control which inherit from the Table class and in the constructor, it takes a an integer as an argument. There is no empty constructor.
Is there a way for the user to set that variable in the properties window after they drag the control onto a form.
I know some .NET controls, you can set the source for the parameter to different things like another control's property, QueryString using just the properties window.
Right now, I have to create the control dynamically. I read the query string and then created the object.
I created a simple gridview user control with a custom property ProfileType which should load different records depending on the ProfileType value when attaching to a web page.
This is my web page:
[code]....
how I can expose user control custom property at its code-behind file.
here's a situation and I would appreciate your response.
I have programmatically created the Wizard control:
Page_Load(obj s, evargs e)
{
Wizard ClaimDetailWizard = new Wizard();
foreach(int item in selectedItems)
{
//create new step
//added custom control to new step
//add step to wizard
}
//added wizard to a placeholder on a page
}
Based on List I get from Session i added new steps to my wizard To each step I had added a custom control
Each custom control in tern contains another custom Gridview Control in it.
So here's the problem when the page loads for example for two steps. All is good Wizard does what it's supposed to do.
But when I try to use sorting or paging in that custom Gridview. Somehow it displays the gridview I should see in the next step of the wizard.
Also what I'm noticing through debugging. Is that when I press next in the wizard I go back to the original page where I do all of the code specified above, and it recreates the wizzard. But it goes to the next step. Is this the way wizard supposed to work? Just doesn't seem very efficient.

View 1 Repliescreated a Custom Textbox Control that is intended to be a "masked date" textbox, so that I can handle different ways a user might enter in a date and make it work no matter what.I did this by creating a custom control with 3 separate Textboxes one for month,one for day one for year,then do some handling for different things that could be entered and it would all work.
The problem I am having is,when I add this control to the page,if I do an alert to check the Text value of the custom control it just gives me "[ServerControl1]" even if I enter in a date.
I tried doing an AutoPostback after entering so that it would refesh the Viewstate to have the values of the textboxes but the control doesnt seem to actually postback, even though I have it enabled.accessing the Textbox value after someoen
has entered a date?first custom control I have created and have been using google.
