I have encountered a problem using a janus grid. I have created a dropdown and bound a datasource to it. The datasource is filled with data, but when I use the dropdown it doesn't show any values. I can choose one of the hidden values and the cell text is updated fine. It looks like the values are there but for some reason I can't see it. I have already checked the font properties.
What might be causing this?

This should be a lot easier than it appears to be, but I'm having an issue with it.
Conditions
If upon entering this specific page, if there is only one record in the grid (based on a status value in a dropdown), hide the grid and show a table with the details of that record.
If there is more than one record, display the grid with the records.
When a record is selected, display the table with the details of that record.
When I go into the page currently, there is only one record, so it is displaying the table. If I change the value of the dropdown to another status, more than one record is in the grid and the table is hidden. Previously (by another programmer) it was being set to Visible = false. Obviously, this is not a property of the table. However, it previously worked as when someone would select a row, they would set the Visible = true and the table would show.
I've now changed it to hide by using:
tblDetails.Attributes("style") = "display:none"
However, trying to replace the Visible = true is not working:
tblDetails.Attributes.Remove("style")
I have also tried:
tblDetails.Attributes("style") = ""
Someone please point out to me the solution that is going to make me slap my forehead. Thanks.
use setAttribute(attr,value) to change the value of each Element You want
like below example
yourelement.setAttribute("style","");//it is to change value
yourelement.removeAttribute("style")//it is used to remove style attrb from your element
I have a combobox, on which I have to choose one option. That option determines which values should be shown on the comboboxes of a grid. The values to show on the grid's comboboxes are on a table. Right now, I'm showing all of them, but I need to filter it down.
The user must choose a value on combobox #1, and the comboboxes inside the grid (#2) should only show the related values. So far, I haven't been able to accomplish this.
Thanks in advance!
Refresh your drop down list as follows:
&l_field.ClearDropDownList();
/* select values required by sql */
&l_sql = CreateSql("...");
While &l_sql.Fetch(&l_key, &l_descr)
&l_field.AddDropDownItem(&l_key, &l_descr);
End-While;
In my ig:WebDataGrid there are two columns that hold boolean values coming from a database; the column is defined via
<ig:BoundCheckBoxField Key="Mandatory" DataFieldName="Mandatory" Header-Text="test" />
Every editing option (be it RowEditing or CellEditing) works fine with the automatically provided CheckBoxes that represent the values. But now I want to use the RowAdding feature. Unfortunately I can't find any EditorProvider that seems to fit for CheckBoxes, and just leaving the definition for the respective columns empty results in the cells not being clickable/editable in the adding row, although there are grayed out CheckBoxes shown and the column is not set to be ReadOnly.
Is there any way to get an editor provider fit for this? Since editing works automatically with the CheckBoxes I feel like there should be an easy way to get RowAdding to work analogously. Otherwise I'd have to go the 'painful' way via creating a DropDown Provider with 'true/false' as values... which would be way less elegant.
The problem turned out to be a bug in the specific Infragistics version we were using. Updating to the latest Service Release of the 14.1 controls fixed this particular problem. Although there is indeed no CheckBox editor provider, those just work by default now.
I have two grids. The first displays keys, and the second displays a list of related items in another table. Since the grids are on different tabs, I put a filter on the pageActivated method for the second grid's tab.
Some pseudo code to get my point across without posting 200 lines of x++
override page2Activated() {
dataSource2_ds.removeFilter();
dataSource2_ds.filter using grid1Field.valueStr();
}
This works nicely, as long as grid1 has rows in it when the form is opened. If there are no rows when the form is opened, even after adding a row to grid1, something doesn't get updated, and grid2 will always be blank.
Then, I tried looking at the datasource instead of the grid fields.
override page2Activated() {
dataSource1 firstTable;
firstTable = dataSource1_ds.getFirst(true);
dataSource2_ds.removeFilter();
dataSource2_ds.filter using firstTable.recID;
}
The problem with this one is that it only works if you click the checkbox next to a record.
I'd like to to work with a highlighted record in grid1, without having to click the checkbox.
Any suggestions?
Question answered in comments above. Posted as answer so the question can be marked closed.
Rather than using code to manually filter the records, link the tables using the datasource properties JoinSource and LinkType. Set JoinSource to the linked table and LinkType to Active.
i am using a data grid in flex and i am generating data from a mysql server. However, my problem is with adding a button within the datagrid so each row has one.
i have set the columns itemRenderer to mx.controls.Button although with the buttons shown in the grid there is no label on them (even though one has been set) and the assigned click event does not trigger when hitting the button. anyone have any ideas or guidance on what i am doing wrong.
Thanks
Mark
