Users want to have the ability on a page to have a treeview with hierarchy that can be updated by dragging and dropping from a listbox. They can drag a change request from the listbox and drop it on the treeview as a parent request or a child of one of the treenodes. There also needs to be the abililty to drag and drop from within the treeview. With all the changes being done, the item from the listbox would also need to have a field changed to either Parent = 'Yes' or IsChildOf = parent id. My first question is;
1) Is all of this possible?
2) Know of any samples or examples of how this would be accomplished?
3) Is there a better way of doing the hierarchy with parent and children then mentioned above (I hope there is)?
4) What have others done for something like this?
I am open to other thoughts of doing this a better way and I'm sure the users can be persuaded. Prepping for a Access conversion project beginning of year. And if this conversion from A2007 to ASP.NET goes well, there is another major conversion waiting in the wings.
iam having a treeview where the sample structure is like this. Cabinet under cabinet there is folder and under folder there are some documents.now i want that documents to move from one folder to another folder using drag and drop ...how can i perform this functionality.
Could you point me to a reference article on how to implement drag and drop within a treeview control using ASP.NET in C#? Is this best implemented with AJAX? I will be using an XMLDatasource. Also, I did not want to use any third party control at this point
I have made a monthly view custom calendar.I have taken a repeater to make the control.Now what i want is there is a treeview showing some data.I drag from that treeview onto Datalist/Repeater control.on dropping the value should be inserted into database
I have an updatepanel with some textboxes and dropdownlists they have autopostback set to true. They are all defined as triggers on the updatepanel. I want the user to be able to change data in a textbox and tab to the next and have the text selected in each textbox he enters. My problem is I receive the first postback fine, make some database updates, then exit. The next textbox is not being selected, so I added thge final instruction in the data changed event to nexttextbox.focus. That seems to work, however the nexttextbox does not have the text selected. How can I do that?
I can't get over the problem with my TextBox. It's inside an UpdatePanel. There is button and code behind for the button_click event that should write the TextBox.Text to a text file, but it does not :-(
Here's the code (I am using Master Page for this page) :
In my codebehind, I'm trying to set it to the date I retrieve from the database, with the following
What happens is that the page is left with just the watermark text, but not the text I'm setting it to. However, if I inspect the textbox in VS it says the text is what it's supposed to be. I read somewhere that a similar error was because of a property referred to as isWatermarked, but I couldn't find it.
I have a situration that I am using asyncfileupload and after uploaded, then the file content will be directly loaded into textbox1. I have a method to get the file content successfully, but I cannot update textbox1 even it is in updatepanelhere is the code to update the textbox1.text
I have a radiobuttonlist control in an AJAX tabpanel, which I would like not to postback whenever the selected item is changed. But I do want to modify the text in a textbox, that is within a separate updatepanel, to be the text of the new selected item.
I write code in asp.net I always solve issues by finding solutions with other members who have the problem before me. But this time I don't know how to do...
This is my problem :
I have a gridview inside an updatepanel and i modified some headers in order to filter the collection. This worked but when my updatepanel is updating, my textbox for the filter clear the value (the text) and lost focus.
This is my code :
The function FilterText(this) only set a timeout before fire postback.
I have a modalpopupextender with popupcontrolid set to a panel. I have a name textbox, label, submit button in the panel. When the submit button is clicked the name is validated using a function connecting to the DB. If It already exists the label should show "Already Exists". I have set the label text in the buttonclick event handler but the label is no set. The popup just closes. I want the label to be set and make the popup remain unclosed. How to achieve this functionality ?
