This is really for anyone that is using the chart controls and not just the admins. I have the controls working as expected, but I cannot come up with a suitable layout that I like and still works when the form is maximized. By "work" I mean still looking acceptable. For example, when the form is a fixed size, my layout looks fine but when I go full screen on a 34" monitor, there's a ton of unused space and the form looks like a hot mess.

What do folks do in this scenario? I don't have enough charts to fill up that much real estate and if I did, they surely wouldn't fit on a smaller form. Also, I probably wouldn't want to fill up a large monitor with that many charts. 

Are dev's giving the user the ability to build their own dashboards PowerBI style? 

For now I think I'm going to make my form a fixed width and keep moving forward. I will have to circle back to the layout challenges later.

Just curious to know what folks do when they hit this. 

Thanks,

Michael. 

Hi,

I have one RadGridView for WinForm UI.

I bind data dynamically using DataSource property and bind DataTable that is returned from database.

Before binding datasource, I add a GridViewCheckBoxColumn to the RadGridView (for selecting all rows).

following is the sample code:

If RadGridView1.MasterTemplate.Columns.GetColumnByFieldName("").Length = 0 Then
            Dim checkBoxColumn As GridViewCheckBoxColumn = New GridViewCheckBoxColumn("")
            checkBoxColumn.EnableHeaderCheckBox = True
            checkBoxColumn.HeaderCheckBoxAlignment = ContentAlignment.MiddleCenter
            checkBoxColumn.AllowFiltering = False
            checkBoxColumn.CheckFilteredRows = False
            checkBoxColumn.HeaderText = String.Empty

            RadGridView1.MasterTemplate.Columns.Add(checkBoxColumn)
            AddHandler RadGridView1.HeaderCellToggleStateChanged, AddressOf RadGridView1_HeaderCellToggleStateChanged
        End If

Later I bind the data table:

RadGridView1.DataSource = dataTable

Now, I have 2 problems:

1. Checking / Unchecking header check box, checks/unchecks checkboxes of current page only.  I need to perform the operation for the whole grid.

2. I have got filters on.  User can select filters on columns.  Once filters are applied, records are displayed according to those filters (other records are hidden).  Now, when checking the header check box, it only selects records that are part of current page.  For example, if I am on first page and apply filter on one column, grid will hide all rows from the first page that do not match the filter and pull records from 2nd and 3rd pages that match the criteria and show on the first page.  But if I select check box in the header, then only records from first page are selected, records that came from 2nd and 3rd page are not selected.

Kindly help.

This is more of a curiosity question. Sometimes I add a single item to my listview when I'm "Loading" or displaying other types of informational messages. Out of curiosity, is there a way to add an item and specify its column index all in one line? Right now I create the item, then specify its column index, and then set the text.

Say I have a RadListview created, columns already added are A,B,C,D,E. I want to simply add some entry under the Column "C" that says "Loading" but all in a single line of code.

This is not important, just curious if there is an easier way of doing it vs :

            lv.Items.Insert(0, new ListViewDataItem("Test") { Text = "Test" });
            lv.Items[0]["MyColumn"] = "Test";

Thanks!

Hello,

I have a small amount of data that's already been grouped and sorted by sql. It looks something like this:

value - category name

25 - Cat1
15 - Cat2
5  - Cat3

Each time I run the query, I may receive different categories with different names and different values. These categories, if I understand how the ChartView works correctly, are represented via Series. Since my data is dynamic, how should I go about creating these series on the fly? Most of the examples I've seen use hard coded series. I'm sure I can hack it together, but I'd rather ask first in case there's a better way. Btw, I did search the forums and found a post where someone is using VB and Linq to get a list of categories. That may work, but its from 2012 so I thought I'd ask.

Thanks!
