Telerik RadGrid Doesn't Seem To Export Grouped Data?
Jan 5, 2011
I've got a DNN application using Telerik RadGrid. We're exporting some data from the Grid but when we drill down on the grid control and export the data we only see the initial top level data, never the updated Grid. Here's my table tag and supporting code. I'm not an expert in ASPX/C#so please forgive my newbie-ness.
I have a page with a drop-down. Based on the selection in the drop-down, data gets loaded and populates a RadGrid. I am using a custom user control for the EditTemplate, so I can't use radGrid.DataBind(). Instead, I have to use radGrid.MasterTableView.Rebind() in association with a NeedDataSource event handler.
My problem is that when I load the page initially, I populate the drop-down and automatically select a value (first item in the list) which triggers the databinding on the RadGrid. I can step through the code in debug mode and see that the grid is being populated with data, but when the page displays, it doesn't get rendered. When I then manually choose an item from the drop-down, which triggers the same grid databinding code, it displays properly the second time.
How do I get it to display the grid the first time the page loads?
I was creating another usercontrol with Telerik's RadGrid and Calendar.
[code].....
The problems are, (1) when I click the submit button. the data in the RadGrid is not changed. (2) how can we check if there is nothing selected in the Calendar controls, because there is a date (01/01/0001) set even if we do not select anything from that calendar, thus Calendar1.SelectedDate != null is not enough.
I've tried to find the answer, but am not having any luck and am wasting to much time trying to figure it out. Using RadGrid from Telerik, latest version of their Ajax Controls, I've added a Select to each row, and can't figure out how to get the value of the selected row. Prefer to get the value of the ID column (from ID field in my database) or other specific columns. C# or VB example will work, VB preferred.
I have a RadGrid with filtering. I set AutoPostBackOnFilter="true" and CurrentFilterFunction="Contains" on my columns. Ok it works fine, user don't have to open drop-down list to select type of filter. But now, I want to hide filter buttons.
I need to collect additional information from the user when they initiate a delete on a radgrid. Right now I am presenting the user with a confirmation dialog box that lets them click "OK" to continue but I need to add an additional textbox to collect a reason.
I have a radGrid on the page with the "Add New Record" button. When I click the "Add New Record" button, a textbox appears above each column that allows me to enter values. I want to limit the number of characters that can be entered in the textbox. How do I set the MaxLength of those textboxes
I have a checkbox column in a RadGrid that I want the user to be able to check/uncheck it and set the attached property. When the grid renders however, the checkboxes are disabled, because the grid is not in "edit mode". All the examples I'm finding want me to go through a lengthy process of selecting the record, putting it into edit mode, changing the value, saving the value.... yada yada yada...I just want the whole grid to be in edit mode (or the column, or whatever works) from the get-go, so the end user can make a one-click change to the data value. I know there must be a way to do this, I just can't seem to find it.
I'm getting a blank column when switching to another page using the default pager in the telerik radgrid. As data for each row, it shows the type of data i am using for the rows (SearchRecord)
Anyone have any clues as to why this may be happening? It doesn't show up on initial population of the grid, but only when I do paging. My columns are built dynamically but i confirmed that when my columns are built, they are the correct number.
When handling the OnUpdateCommand event on a RadGrid the DataItem is null.
I thought that this would also represent the data item being represented by the row.
The Radgrid is populated from an IList and in the handler the code looks like this...
protected void rgAllocatedClients_UpdateCommand(object sender, GridCommandEventArgs e) { if (e.Item is GridDataItem) { var gridDataItem = e.Item as GridDataItem; var client= gridDataItem .DataItem as Client;
This works find when handling the ItemDataBound event but not when handling the UpdateCommand event. I really need this as in my Client class is the Id of the row I want to handle the update for.
I wanted to ask what is the best practice to manage width of the radGrid.
For my application most users are running 1280 x 1024 so I would be happy to set my overall grid width to 1100. However, depending on the form in use, I sometimes have horizantal scroll bars. To solve this, I have been playing with the width of the grid, and also I have played with setting the itemstyle-width for one or two columns. Sometimes I accidentally get it right, and sometimes it is not quite right.
What is the best way to manage this? Do I set the grid, and then all columns, or just the grid, or just the columns? I guess there is a best practice, so just wondering how you handle it,
Using VS2008, and Telerik radGrid version 2010.1.519.35
I have a about 50 DNN modules using telerik radgrid and I need to display my dates in dd/mm/yy format. It is possible to do this easily in view mode, but when I switch to edit mode, it is more of a struggle. I can write a snippit of code to reformat the displayed date values to dd/mm/yy, but for inserts the user must enter mm/dd/yy.
IOW, I need to change the culture of the form to en-GB culture.
In my DotnetNuke App, I have made a change to the web.config, but it still assumes en-US format.
I am not sure whether I need to set this at web.config level, page level or at the column within the control.
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 have this webform which displays data from the databasenow I have an export button for it which exports the data but not the one which is displayed in the grid it duplicates the data with same name and doesnot show full address just shows firstline of the address in the grid and doesnot show the country.
I am facing serious problem while trying to work in clientevents provided with asp.net mvc telerik grid. Here's the two different scenarios:When I am putting the following script in a view or partial view it works fine;
I've got a LINQ to SQL object, and I want to group the selected data and then pass it into a view. What's the correct way of doing this? I'm sure I need to group the data when I select it rather than grouping it in the view, as this will result in about 200 rather 50000 rows I need to pass into my view. Are there any good examples of this online that anyone has seen?
I need to create a grouped checklistbox dynamically from the database, I was able to do it using an TreeView Control, But I need to move it to a Checklistbox. Below is the logic in VB.NET for the TreeView
