Hi Rajesh,

I would initially like to acknowledge the fact that you have taken the extra time and effort to further provide the relevant DropDownList TagHelper editor that is currently held on your premises. I really appreciate it.

Based on a previous communication of yours, I presume that the current scenario in which the DropDownList resides is within the boundaries of a given column's editor template. Are my suppositions correct?

If this is the case, then the reason for the sporadical behavior would most notably be caused by a disparity between the "datavaluefield" TagHelper attribute of the DropDownList, and the "Team" column's annotation. Taking this factor into consideration, a possible recommendation would be to alter the column declaration in the following manner:

<columns>
    <column field="Team" width="250">
        <column-editor-template>
            <kendo-dropdownlist name="Team"
                                datatextfield="Team"
                                datavaluefield="Team" data-bind="value:Team">
                <datasource>
                    <transport>
                        <read url="@Url.Action("Teams_Read", "Home")" />
                    </transport>
                </datasource>
            </kendo-dropdownlist>
        </column-editor-template>
    </column>
</columns>

This should then produce the following visual representation upon the instantiation of editing operations:

For your convenience, I have also altered the sample from the aforementioned linked forum case for you to observe additionally.

Please let me know if this helps resolve the issue.

Kind Regards,
