I tried both, loading the usercontrol when needed and I also tried adding it directly into the aspx.
Nothing worked. With the second one (what's meant to be the easiest option) I tried with delegates and events (but can't access de usercontrol event from page) and tried with properties (I can access properties but they're always empty)
I have a DetailsView control bound to an ObjectDataSource within a User Control (.ascx). It appears that the DetailsView.OnDataBound event is being fired on every page load or postback.
I do not see this behavior with a similiar DetailsView directly placed on an aspx page.
how to use gridview usercontrol (Ascx) and sql pass to aspx page
View 4 RepliesSo what I'm trying to accomplish is this
[Code]....
The user control has public properties named accordingly and the page has protected properties accordingly which I've verified have the desired values.
For some reason the values are always empty strings or 0s in the usercontrol, no matter what the page property is.
I have a custom control that I have created. I want to be able to pass in a Javascript snippet for a callback function. I am able to do this by passing a string back. The problem is that in the Javascript, I need to reference another server control that is not related to my custom control. So, I need to be able to pass in the ClientID of that control for use in the Javascript. Here is a snippet of what I am trying to do:
[Code]....
Now, I realize that '<%= chkStartDate.ClientID %>' will not be parsed. But, I need it to be parsed so the OnClientOnChangeEvent property of my custom control can take any Javascript for use as a callback. In this instance, I need to pass in the ClientID of the control for the Javascript function to find the control to work with; and this seems to be the one issue that I don't know how to handle.
I have two files in my project. One is user control (popup) customerpicker.ascx and one is default.aspx page. In customerpicker I have dynamically generated gridview and 'select' column with SelectButton.
What I want is this: When I click on 'select' on random row in gridview, then I like to display value from selected row immediately (like ajax) to aspx.page. How it is possible?
There is part of my code in .ascx:
public string showOnaspx { get; set; }
protected void GridView1_SelectedIndexChanging(object sender, GridViewSelectEventArgs e)
{
GridViewRow row = GridView1.Rows[e.NewSelectedIndex];
showOnaspx = row.Cells[1].Text;
e.Cancel = true;
}
protected void GridView1_SelectedIndexChanged(object sender, EventArgs e)
{
GridViewRow row = GridView1.SelectedRow;
//row[i].Attributes.Add("onclick", "$('#ContentIndex_sometextbox).val(" + row[i].Cells[1].Text// + "); $('#Close').click();");
}
I also tried with jqeury (comment in selectedindexchanged function), but it does not work well, because user have to click SELECT two times to effect.
I have a particular scenario and I would like to know how I can implement it in the most efficient way. I also have some queries related to this. The application is a AJAX 1.0-Enabled ASP.NET 2.0 Web application.
I have a link, which when clicked I need to show a pop-up div. The contents of the div will be displayed using a usercontrol. The usercontrol will display the contents based on a query string value.
I would like to know:
1. How can I implement this in the most effecient way. I don't want to use a separate page on which I will have the usercontrol and then display the page in the div.
2. Suppose I call a JS function ShowDiv() on the click of the link, to display the pop-up div. Say, I call the function this way ShowDiv('querystring'). Now how will I pass the value 'querystring' to my usercontrol.

View 4 RepliesI have a User Control which has a dropdownlist.
Now i want this dropdownlist value in parent page in a label control.
whenever i change dropdownlist value label value should be change.
How can i do it?
I created a customDropdown usercontrol with Events and It worked fine.
Now I stored the path of the ascx file in the database table and i want to Load the ascx file and handle the Events dynamically in an aspx page.
To Load the usercontrol and access the public properties and method, I need to know the object i am trying to load, right?
For Example
FeaturedDDL c = (FeaturedDDL)Page.LoadControl("~/FeaturedDDL.ascx").
But I dont want to hardcode objectType "FeaturedDDL", coz i dont have that stored in my Database field.
Since I am loading the usercontrol by getting the path and name of the usercontrol from the database table,how will I know the ObjectType at that time?
How to accomplish that and also how to handle the events for these type of situation?
I have a user control that consistes of a dropdown menu, a label, a textbox and a button. It resides in a html table, what i would like to do is on a keypress, such as the "insert" key, i would like to add the same control again directly on the next row, I have used programs that do this, but for the life of me can't figure out how its done...

I'm working with a simple UserControl someone at my company created. It's basically just a DropDownList with a RequiredFieldValidator and some added properties (such as "Required", which controls the CSS styling of the DropDownList and whether the RequiredFieldValidator is Enabled or not).
Here is an example of the UserControl usage where a SqlDataSource is used to populate the ListItemCollection. I'm trying to specify an intial ListItem below (and would like the ability to add multilple ListItems if necessary) but can't seem to get this to work...
[Code]....
My code-behind looks as follows:
[Code]....
I've found several posts related to this but cannot seem to get the declarative ListItem to be added to the DropDownList.
I understand that using a WebControl is another option, but I'd like to learn how to get this method to work if possible.
How can I create a UserControl with a collection-type property which has a collection editor?
I've a CompositeControl with an ArrayList-type property which has CollectionEditor-type designer. You can see this property on Properties window with a "..." button which launches a collection editor. This works fine and all but I want to apply the same to a UserControl and I've couldn't manage to pull it off so far. I've done the same thing what I've done with my CompositeControl but the property either doesn't even show on Properties window of the UserControl or shows as a single value property with no "..." editor button.
This is what I've done with CompositeControl:

How can I pass the Membership.GetUser.UserName variable (or any variable) through a user control parameter at load time?

The only thing that I was able to do was to create the User Control object in the code behind and then add it to the page. Although that works, it doesn't seem like the correct way to program.

I would like to convert some aspx code in user controls. This would lead me to having a master user control that contains other controls inside.
The contained user controls have datasource with some control parameters that takes the value from a control present in the aspx (now) and that will then moved in the container user control.
which is the best way to handle a scenario like this?
Senario: Masterpage with a UserControl and a child ASPX page
In the past when using this senario I've used an Interface as a way to pass a value from the UserControl (embedded in a master page) to the masterpage code behind then consume that value in the child aspx page.
My question is now that asp.net 4 have arrived is this still a good way to achieve this or is there another or perhaps better way to do it? I've read somewhere that perhaps "delegates" is perhaps another route to take.
im creating site with usercontrols. I have repeater, inside it is another repeater with usercontrol. My problem is passing BindedValue to usercontrol.Bindings works fine and binds the value i need but it cannot pass the value to usercontrol. When i type it manually it works, when i bind it, it passes null (!).I've tried get,set, functions (ondatabound, onload, oninit), accessing control from code with no luck. Ive read and tried to do all the google solutions but with no luck. (even with creating usercontrol inheritance)
