![how do I add a panel with an image control and a label dynamically (on button click)??][1]
i want this:
i select an image and press delete, it should delete (from the database) the image and the image name (label)... i press add and a new image control with a label should be added...
problem:
i cant seem to be able to select anything on the page...
what i have:
i have put the image and the label in a panel.. i delete the panel and it gets deleted... however, since the PANEL is not stored in the database, it only gets deleted temporarily.. it comes back the next time... what should i do to achieve what i want here..?
i have taken a repeater control & put a panel with an image & label inside it (i will have multiple similar panels in the repeater)... now how do i delete a particular panel from it...??

The case:
I have Activities as datamodel.
I have set Activities to have many-to-many relationship with themselves to represent a Parent / Child relationship.
I have set up an accordion widget. Each row of the accordion contain basic data about the Activity record + some buttons.
I have set one of the button's onClick functions to open a popup, which allows me to edit the Activity detail in a form.
When I click a different record from the same accordion, the form from the popup reflects the data in the selected record.
The problem:
I have nested accordions which represent the "Child" Activities of the Parent Activity.
I have also added a similar button, which opens a popup. I can open the popup, which targets the child records, but cannot make it open the specific record, from which I pressed the button.
So the popup open by default on the first child.
Please help - how can I make the popup change naturally to reflect the datasource / selected record of even nested datasources?
What I tried:
In order to try and make to popup work I have tried to set the datasource based on the relationship:
Activities: Sub_Activities(relation)
This works to the extent of showing the related items, but popup content does not dynamically change on clicking a different child record or clicking the button from a different child record.
In both cases what is shown is the first child record.
What I understand is that you have a set up in which you click a button and a popup shows. The popup should let you view/edit the record referenced in the row where the button is. If that is the case, then probably you already have almost everything setup for the next thing to work. First, add a string custom property to the popup and name it selectedKey. Then, on the onClick event of the button that opens the popup, add something like this:
var key = widget.datasource.item._key;
app.popups.MYPOPUP.properties.selectedKey = key;
app.popups.MYPOPUP.visible = true;
Now, go to the popup content and add the following on the onAttach event handler:
var key = widget.root.properties.selectedKey;
widget.datasource.selectKey(key);
This is the general idea of how to make it work; However, in order for it to work, your datsources in the widgets should be properly set up. Good luck!
I have two drop down lists and one panel in my content page. The panel is not visible. What I want to achieve is when I choose the first item in the first drop down list, the second drop down list will change according to my first list's choice. I have done this part by storing the data into the database and retrieving the choices from the database.
Then, when I choose from the second drop down list, I wish to show the panel. I stored the panel name into database already. I can retrieve the panel name from the database, but I'm not sure how to proceed.
How can I get from that string (panel name) to the panel object and set Visible=true?
put the panel in other asp.net panel with id "pnlParent" or div with runat="server" then in your code behind try :
Panel pnl=(Panel)pnlParent.FindControl(your_dynamic_id);
I have something like this to enter staff details list. Above is the table list. User click button below the table to add new list record. Then fill in the list details on the form beneath it.
My question is how can I just allow user to enter/fill in the list details directly on the table itself. Not only that, also user able edit record whenever the user clicks the records and wanted to change them.
The example I am providing is specifically for a datasource in autosave mode, so you will need to make some adjustments since it appears that your datasource is in manualsave mode. First you will either want to recreate your table and in the table creator choose 'Editable' which will automatically place inputs in your table row vs labels. Alternatively you can just replace all your labels with Textboxes, Dropdowns, or whatever your input should be. See the image of the table creator below:
Since in my example I used a 'Insert Only' form I moved my 'Create Button' and my 'Clear Changes' button inside the formbody, then set the flow direction of the formbody to horizontal and then matched the spacing of the form fields to the same as my table row and dragged the formbody to be between the tableheader and the tablebody(list) element. See the image below:
Again you will want to make adjustments to fit your needs such as rearranging where your 'Save' and 'Reset' buttons appear and in manualsave mode you may be able to skip the formbody entirely since your 'Add Details' button should automatically create a new table row anyways which you will then be able to edit directly in the table, you may just need to find it first but generally new rows should just be added on the bottom of your current datasource page.
I'm using vb.net. Basically, I have a drop down list, text box and a submit button. You choose a movie director from a drop down list, then type in a movie, click button and it adds the data to my database.
There's another button which hides/shows drop down list, text box and submit button using Visible = True and Visible = False, but what I don't like about it is when it hides the things I said before, it leaves some white/empty space like if they are still there, but not visible.
Is there anyway to put some kind of holder/container and place a button which when clicked could add my drop down list, text box and submit buttons to that place?

I assume that you are working with WinForms in Visual Studio. In the Toolbox the controls which could help you out of this situation are in the "Containers" section. Among others, there is a Panel, a FlowLayoutPanel and a TableLayoutPanel (see this video on msdn for a TableLayoutPanel Demo). They can help you to organize controls. Especially the FlowLayoutPanel places the controls automatically. But you can always change the Top and the Left properties of any control, to move them around to the desired place or group some of them on a Panel and change the Location of this one one.
You can add a control to a container by using the Add method of its Controls property. However, if the control is already on the form (since you are asking how to add an existing control) you must remove it from the form before.
Me.Controls.Remove(myButton)
panel1.Controls.Add(myButton)
I have a Listview in my aspx page with Insert template and Edit template. and a Add New LinkButton.
When a user clicks on Add New LinkButton I am able to specify Insertitem Position so that the Insert TEmplate appears at the bottom of the listview. But how to I make the edititem template to appear at the bottom like the Inserttemplate
Its not available for the EditItemTemplate.
You'd have to actually save the original position, move the item in the data source itself (probably IList compatible), rebind the view, trigger editing on the new position, then swap the data item back to the original position.
I wouldn't recommend it. It's nonintuitive behaviour for users anyway; when I decide to edit something I should either be able to edit in place or edit on an entirely separate form. It's very rarely good UI design to shuffle items around while users are working on them, especially if you have any sort of scrolling/paging going on.
