Asked On August 11, 2019 01:55 PM UTC

I would like to have a listbox that shows information in multiple columns, not one column. If possible, please give an example

2. Is there any reason behind for showing the data in multiple columns in ListBox? Is yes, kindly share the details? 
3. Share your exact real time use case scenario of your requirement. 

Could you please check the above details and get back to us with the above requested information, based on that we will check and provide you a better solution quickly.

Because of the large amount of data, it scrolls and is unpleasant to the user. Half of the page width is left blank. But if you have a few columns in the box list, it doesn't scroll and the whole page width is filled

Hi Ebi, 
 
Thank you for your update. 
 
We have checked your reported requirement, “To display items in multiple columns rather than in single columns based on width” and it can be achieved with some CSS customization in ListBox as like in the below code example. 
 
CODE SNIPPETS: 
 
 
<EjsListBox Value=@Value DataSource="@Data" TValue="string[]"></EjsListBox> 
 
<style> 
 
.e-listbox-wrapper .e-list-parent { 
    display: flex; 
    flex-wrap: wrap; 
} 
.e-listbox-wrapper .e-list-item { 
    width: 25%; // adjust the width of the list item based on your need. 
} 
 
</style> 
 
@code{ 
    public string[] Value = new string[] { "Hennessey Venom" }; 
    public List<object> Data = new List<object> 
{ 
        new { text = "Hennessey Venom", id = "list-01" }, 
        new { text = "Bugatti Chiron", id = "list-02" }, 
        ..// 
    }; 
} 
 
For your convenience, we have prepared the sample based on our suggestion. Please find the link below. 
 
 
Could you please check the above sample and get back to us, if you need any further assistance on this.

Hi Sangeetha M
Thank you very much. Your support team is great. It works great
But all of the listboxes in a page are displayed  in multiline mode.
If possible, give us an example to display a custom listbox in a multiline mode

Hi Ebi, 

Thank you for your update. 

We have checked your reported requirement and it can be achievable in ListBox using CssClass property as like in the below code example. 

CODE SNIPPETS: 

<EjsListBox Value=@Value DataSource="@Data" TValue="string[]" CssClass="e-custom"></EjsListBox> 
 
<style> 
.e-custom .e-list-parent { 
    display: flex; 
    flex-wrap: wrap; 
} 
.e-custom .e-list-item { 
    width: 25%; 
} 
</style> 

For your convenience, we have modified our previously updated sample based on our suggestion. Please find the link below. 


Could you please check the above sample and get back to us, if you need any further assistance on this.

Sangeetha M ,
Unfortunately it's not responsive and doesn't work well in mobile mode.
Please see the attached video

We have checked your reported issue, we have suggested to use the media query to resolve the listbox mobile mode issue. Please find the below code snippet: 
 
Index.razor 
<EjsListBox Value=@Value DataSource="@Data" TValue="string[]" CssClass="e-custom"> 
            <ListBoxSelectionSettings ShowCheckbox="true"></ListBoxSelectionSettings> 
 </EjsListBox> 
 
 
<style> 
    .e-listbox-wrapper .e-list-parent { 
        display: flex; 
        flex-wrap: wrap; 
    } 
 
    @@media (min-width: 320px) and (max-width:480px) { 
        .e-custom .e-list-item { 
            width: 100%; 
        } 
    } 
 
    @@media (min-width: 480px) and (max-width:780px) { 
        .e-custom .e-list-item { 
            width: 50%; 
        } 
    } 
 
    @@media (min-width: 780px) and (max-width:1920px) { 
        .e-custom .e-list-item { 
            width: 25%; 
        } 
    } 
</style>
