Hi,
I am trying to use a jquery ajax call to get my data for an htmlchart and am fine with the data itself but when I come to add it to the chart I would like to dynamically create the series on the fly. With that in mind please could someone supply me with an example of how to create a new (or several new) series on a chart?
Note that I don't want to declare the series in the tags - these need to be declared from the JS...
Regards
Jon
i am using raidGrid
void BindData()
{
grid_1.DataSource = Names.GetDeailesByGetall(con);
grid_1.DataBind();
}
Hello I am having one issue on RadGrid. I have a simple Employee list which I am binding in Page_Load inside !IsPostBack check.
As soon as, a postback happens (whether it is due to a button click or due to allowsorting (automatic sort)); the grid disappears. This is because NeedDataSource is not executed on postback.
However, if I write RadGrid1.Rebind() then NeedDataSource is executed.
Does this means everytime when a postback happens, I have to call RadGrid1.Rebind() to bind the grid (whether it is due to a button click or due to allowsorting (automatic sort))?
I remember in earlier version we did not needed to call Rebind() method to make NeedDataSource execute.
Please help.
Scenario:
Grid with a GridDropDown column. The source for the drop down is a simple table of name/id pairs. If doing an update in batch mode, and the drop down's ListTextField has trailing spaces, the ListValueField won't be passed back during an update.
See sample below. At line 20 is the code to create the sample SQL data.
When running this sample, if you attempt to update a row and use any of the drop downs that end in spaces, the update will not assign the correct id value. If you change the edit mode from batch to popup, it will work fine. If you change line 42 to read:
ListTextField="name_trimmed" or ListTextField="name_appended"
both of which change the field to NOT end in trailing spaces, it will work as well.
I was able to work around this, but it's definitely a bug in the control. Trailing spaces should not throw of the ListValueField. I'm currently using version 2016.2.607.45

I have a pie chart with many slices and want to set the legend on the bottom of the chart with Vertical orientation of all the items.
If I set the legend position to right or left, the vertical orientation of the items works fine, but will not work on top or bottom of the chart. Is there a work around for this or will I have to manually create my own legend in a table below the chart?
