i'm extending gridview.
i've overried render method, in which i created a html table and added a html row for each data row.
[Code]....
now i want to add link button after table with on click event fired after i clicked it.i've tested following code but it did'nt worked:
[Code]....
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.
I have a custom server control inheriting from CompositeControl. It consists of two RadioButtonlist controls that are rendered side by side in an html table. The number of ListItems in each RadioButtonList is not known until runtime. Depending on how many items each list contains, the RepeatColumns property of each list is set differently. To do this in the handler for the ItemDataBound event I need to get the count of ListItems in each RadioButtonList. How do I expose the Items.Count property of each internal RadioButtonList as a top-level property? I tried using a getter to return the count but this generates a compile-time error to the effect that the count cannot be assigned to--even though I have not created a setter.
Similarly, in the handler for the Submit event, I need to get the ClientID of each internal RadioButtonList to pass to a method that checks for data changes. How do I expose the ClientID of each component RadioButtonList as a top-level property?
I can of course index the Controls collection of the composite control to access the child control and read its properties--but that defeats the whole point of making a complex, independent custom server control.

Why custom Gridview control not render html properlies under <Columns> properly in Visual Studio 2005?
For example:
[code]....
I have a web user control that represents a simple message box. It is used to display simple messages like "Item has been deleted", or "The item was saved successfully".
On the other hand, I have another web user control that represents the item in the form of an editable form (I made this a user control because this is used in two different pages). I want to embed an instance of the message box user control inside the editable form. I am writing this right after the @Control directive:
[Code]....
Instead of using @Register directives, I register the user controls in web.config and so far this has worked just fine.
With the above markup, the project compiles, but whenever I try to navigate to a page that contains this construct, I get an HttpParseException exception. Furthermore, Visual Studio states that the tack w7rc9:MessageBox doesn't represent a known control.
What am I doing wrong?
I have a server control which consists of a gridview with custom navigation&information capabilities and with javascript functions to highlight the selected grid items or highlight when mouse over event occurs.. (full tested outside asp:wizard)I'm trying to use that server control inside a template wizard step, when I drop such server control in the first step of the wizard everything goes ok.
When I insert even a blank step previous to the step which contains the server control, the javasript code of the server control is not rendered at all, the page doesn't fail during load but until I go with mouse over an item of the grid for instance.When I check the rendered HTML I can see no HTML, nor javascript events of this server control where rendered, neither the implementation nor calls to javascript, but even rarer what is there visible in the grid for ie, even the other components of the server control, are not in the "view source code" content. I seems it was sent to the client, even showed, but truncated in some phase..
I am writing a custom control by inheriting "Control".
I wany the custom control to have multiple control nested inside it i.e. my custom control can have other controls in it.
How can I do it, would I have to implement any interface or what.
At the end, I want the code to look something like this.

I need to develop control (template or user) which must have subtags with some items.
For example :
<SomeControl runat="server" id="scTest">
<column1>TestColumn1</column1>
<column1>TestColumn1</column1>
<column1>TestColumn1</column1>
</SomeControl>
This control may contain some other web server controls such as GridView.I need explanation of experienced developers, how to do that - take me to the right way

I'm trying to develope a collapsible panel control with designer.
I have the following two classes:
[Code]....
and this one:
[Code]....
In fact, the designer class is a copy of a sample class in MSDN and I only tried to customize it to work for me. I'm not sure if all methods are necessary or not.
I have the following two questions:
1- When I use this contrl in design mode, I can add or delete controls to it, in the html view, tags are not updated. so when I close the page and open it again, all changes are lost.
2- I have added this control to the same asp.net project that is using this control. Isn't there any way to have this controil in tool box?
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.
If a composite server control normally encapsulate styling information inside, it is an example of code encapsulation and modularization. However if css properties are included inside the composite control, it is not ideal for code/styling separation and css code re-use principles. Now which consideration should be the main consideration?
View 2 RepliesI'm creating an ASP.NET Control which has a property collection for Columns which the user can edit in the Property Collection Editor..
In most circumstances this works fine, the collection can be edited in the designer and the appropriate tags are added inside the control in the ASPX file.
It works fine when
My control is added to the form
[Code]....
My control is added inside an Update Panel
[Code]....
[Code]....
However, if My control is inside a Content Placeholder which is inside an Update Panel, it fails to work as it should. In this scenario, when the Columns collection is edited in the designer, if you then switch back to Source view, the Columns collection is emptied. I have to save the aspx page before switching back to Source view for the changes to be kept.

how to get around this problem? Is there something I may have missed?
Here's the code for the Control

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.

View 3 Replies I have created a user control and am ready to convert it into a custom control. I am trying to follow:

I am not seeing Build / Publish Web Site option.
I am using VS 2008. I only see Publish User Control but it doesn't give all the settings mentioned below. When I do publish user control, it just copies the ascx file to the desired location. how can I convert the user control to custom control.
I'm new to custom server controls and I'm hoping to use them to build various 'modules' for different sites I build to cut down on duplicate code.I'm familiar with custom user controls in which I can create an .ascx & .ascx.vb file which can then be imported into an .aspx page and used freely.However, with custom server controls I cannot find a way of using markup/html code. Is this possible at all or must all code be created programmatically?
