ASP.Net Nested GridViews – GridView inside GridView with Expand and Collapse feature this artical works for me but i want to expand first row when page is loaded all the other record show as same as it is collapse. may be it is happen in this nested gridview
I want to populate the search results in grid. The results should be grouped based on condition. I mean if i am searching for name called Osama laden, all the names containing Osama be grouped(+) and Laden as well. I should get the count side to the (+) button. When i click on + button the results should expand and when i click on(-) the results should collapse.
I have a Radtreeview that sits inside a RadGrid. For some reason the expand/collapse buttons of the Treeview are not working. I can expand the Treeview initially, however the NodeExpand event never fires.(a postback does occur to the server, and I have several buttons on the treeview node that work.) Once the node has been expanded, the collapse button doesn't work, and clicking on it does nothing.(no postback to server). I have the ExpandMode set to ServerSide. However, if I change the Expandmode to Clientside it works properly.
I really need the control to work with ExpandMode set to serverside, to reduce the loading for large Tree's.
Im not sure if this matters. But I am adding the Events to the RadTreeview when the event RadGrid_ItemDataBound is fired.I am noticing one strange behavior, that I cannot explain either, if I do not attach an event to NodeExpand It fails to open or close. Also the NodeDataBound event fires successfully and the data is loading fine into the tree.
RadTreeView tree = (RadTreeView)e.Item.FindControl("RadTreeView1"); tree.NodeDataBound += new RadTreeViewEventHandler(RadTreeView1_NodeDataBound); tree.NodeExpand += new RadTreeViewEventHandler(RadTreeView1_NodeExpand); tree.NodeCollapse += new RadTreeViewEventHandler(tree_NodeCollapse);
Here is the decleration of the Treeview in the ascx file
I am looking for a expand/collapse script for a grid view. But after searching around, seems like all sample code are for datagrid instead of grid view. And because there are differences between properties of gridview and datagrid, I can just implement it. Does anyone has any reference for grid view?
I am using gridview with two fields called item name and description. Here my intension is when i click the description row. in the gridview, Then gridview should expand big size that showing full description and again click the row it should row size becomes normal size. The gridview should maintain the fixed row height when it bind.
I am trying to use a treeview control in my application. From the begining I had one parentnode and several childnodes for each parentnode. I wanted to be able to close an opened node when I click on a new one and I maneged that with OnTreeNodeExpanded method.
My problem is that I now need to expand my treeview so it will look something like this:
What I want now is:
1. to be able to close an opened parentNode if i click on some other parentNode,
2. if i click on childNode i want to expand it so I can see grandchild,
3. if i click on another childNode for the same parentNode I want that the allready expanded childNode collapses and that the childNode I clicked on to expand.
This is so frustrating...that such a simple feature should not be included in the design of this control. I am using the cssfriendly adapters and the rendered code is shown below.
I thought I might be able to use the adapter's treeview JS function ExpandCollapse__AspNetTreeView(this) since this is what is called when I click on the node that causes it to expand/contract. But that did not work.
I have seen other code posted but it seemed to imply the treeview was a table not a ul.
Does anyone know how to simply expand or collapse all nodes from a link button without doing the postback. Of course the postback works but what a waste to have to postback to do such a simple action.
Why doesn' t MS consider the users and developers when creating these controls and tools? Stupid!
