Update one dropdown, and other dropdowns with the same value update too

Given the following example:


When you update the value for a dropdown that has the value "Country1", the other dropdowns that have that value also update.


- Although the example above uses, we are able to reproduce this in
- The ng-model applied to the element (by the ej-dropdownlist directive) uses the value of the variable that is passed in to the e-value attribute. As a result, it seems like all three dropdowns are using a newly created $scope.Country1 variable.
- I don't know whether this is a bug in your control, or whether we're using it incorrectly? Please advise.

Hi Greg,

Sorry for the inconvenience,

We have confirmed that the issue “When assign value instead of scope variable in  ‘e-value’ attribute in DropDownList[angular], it’s not rendering properly” is a defect. The fix for this issue will be included in our Volume 4 SP1 release in February 2016

Hi Greg,

Thanks for the patience,

We suggest you to use the grid’s default angular template feature instead of external element compilation to render the ejDropDownList inside the grid since it compiled against current scope. Please find the below code snippet

<div id="targetsGrid" ej-grid e-datasource="data"

                     . . . .


                    <div e-columns>

                       . . . . .

                        <div e-column e-field="accessGroupMarking" e-headertext="accessGroup" e-width="100">

                            <input type="text" class="drpAccessGroup" ej-dropdownlist e-fields-id="targetName" e-datasource=$parent.accessGroupData e-fields-text="markingString" e-fields-value="markingString" e-width="100%" e-selecteditemindex="0" e-change="$parent.setTargetAccessGroup" e-value="data.accessGroupMarking" />



Please find the modified sample below.

Please let us know if you have any queries,

Hi Arun.

The e-columns directive looks like a very helpful feature, thanks.

You'd previously stated that a fix was due in the Volume 4 SP1 release in February 2016.

If we weren't to use the e-columns directive, would a fix still occur once we've upgraded to Volume 4 SP1?

Hi Greg,

Thanks for the update.

Query: “If we weren't to use the e-columns directive, would a fix still occur once we've upgraded to Volume 4 SP1?”

We have analyzed further on this issue and we regret to let you know that this issue does not require any source level fix as we promised earlier. We found that using e-columns directive is the proper way to define columns especially templates in angular initialization of grid as we suggested in previous update because without using column directives in angular mode will results in un-expected behavior since all the sub-controls were compiled against same scope. So we suggest you to use e-column directive in your application level to resolve the issue.

Kindly let us know if you have any other queries.

although your modified example using the template feature works for updating a single dropdown if you use grouping on the grid when you ungroup the combo boxes disappear and are replaced by a text box

to reproduce this go to your modified sample 

run it
drag the targetNumber column into the header to group
click X to ungroup
accessGroup column appears as text boxes instead of combo boxes

please can you let me know how to get grouping working for this situation
