I've written a custom date control that inherits the TextBox control, but has it's own three textboxes for capturing month,day, and year separately. I wanted to use the CalendarExtender with it so people could plug in the date that way as well, but I cannot "trigger" the CalendarExtender to show with my custom control.
View 6 RepliesI am trying to accomplish the following.I am displaying records from a database query that include a datetime value. If the datetime value is before the year 2000 (the database defaults to either 1753 or 1900), I want the textbox associated with the CalendarExtender to display nothing. So I created a control library, made a new class 'DateTextbox' and inherited from TextBox.I added the following code:
public class DateTextBox : TextBox

I am using the ajax calendar for selecting date...
I want that the user who enters the date shld be above 16yrs old...
Means i want that the date should be minus from the current date and should be calculated as 16yrs or above it...
For example:- user 'A' selects a date 5th may 2005 and the current date is 28th march 2013 (which means that the age is 8 yrs)... than it should show an error that "your age should be above 16 yrs"...

When I implement Custom web control inheriting ASP.NET Menu Ajax is not working. I try to Override Render method and generate Li's rather than table.I try to use Control Adapters, but when I am not using adapters for some pages ithe base adapter is generating just hyperlinks with span. I do not want this way. So I can not use these.

If yes then why this will happen?
Lets say I have a user control AjaxUC.
<asp:ModalPopupExtender ID="modalSearch" runat="server" TargetControlID="btnHiddenSearch"
PopupControlID="pnlModalSearch" DropShadow="false" RepositionMode="RepositionOnWindowResize"

<asp:Panel ID="pnlModalSearchContent" runat="server">
<asp:Label ID="lblSearchTitle" runat="server" CssClass="modalPopupTitle"></asp:Label>

</div>
<asp:Button ID="btnModalSearchClose" runat="server" Text="Close" CausesValidation="false"

</asp:Panel>
</asp:Panel>
<input type="hidden" id="hdVisible" runat="server" />
------------------------------------------------------------------------ AjaxUC.ascx.cs:-
public partial class AjaxUC : System.Web.UI.UserControl { private ITemplate _content = null; [TemplateInstance(TemplateInstance.Single)] [TemplateContainer(typeof(Container))] [PersistenceMode(PersistenceMode.InnerProperty)] public ITemplate Content { get
{ return _content; } set

This control when used on any aspx page will popup the control placed inside the template "divContent" as modalpopup.

The problem I am facing is that the modalpopup extennder is not coming up as a popup.
Cannot find an explanation of the AJAX CalendarExtender's attribute animated.
What does this do exactly?
when using CalendarExtender with a TextBox, when i press mouse into the TextBox, a Calendar pop-ups. I want to know, does here asynchronous communication took place for bringing this calender from server to the browser ? or initially at the time of page load itself that calendar was loaded in the browser ?

View 2 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.
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.
created 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.
