DataGrid Column AutoFit

[Sarah]

Hello

1- I used AutoFit in the DataGrid Column. Is it possible to set a value greater than the amount determined for the width of the column? For example: AutoFit +10px

AutoFit is very useful, but if the width of the specified column is increased, it will look much better.

2- When we use AutoFit. In some columns, the filter icon is very close to the Column Header. Is it possible to set a greater distance between the Column Header and the filter icon?

Hi Sarah,


Based on your query, we would like to clarify that The AutoFit feature adjusts the column width based on its content, and any remaining space will appear as blank space. This is the default behavior of the grid. It seems that the grid header, including the filter icon space will be maintained. Kindly refer to the attached screenshot and sample for your reference.

Before proceeding with the requirement, we require some additional clarification from your end. Please share the following details to proceed further at our end:

• Could you please share a screenshot of the issue you're facing and explain how you will increase the expected outcome at your end?
• Kindly share your attempt to replicate the issue using the attached simple sample.

The above-requested details will be very helpful for us in validating the reported query on our end and providing a solution as soon as possible.

Regards,
Prathap Senthil

Hi  Prathap Senthil,

The source code is attached. The image below is the output of the source code. I want there to be more distance between the column header and the filter icon.

Based on your requirement, the AutoFit feature adjusts the column width based on its content during data loading. Therefore, it is not feasible to manually adjust the distance between the column header and the filter icon when using the AutoFit feature. We suggest setting the header text alignment to the left and applying the following CSS customization to slightly increase the distance between the header text and the filter icon. Kindly refer to the below code snippet and sample for your reference.

<div id="ControlRegion">

    @if (loadedData)

    {

        <SfGrid DataSource="@lstDataSource" @ref="TreeGrid" GridLines="GridLine.Both" T  ShowColumnChooser="true" AllowPaging="true" AllowFiltering="true"

        AllowSorting="true"   Toolbar="@(new List<string>() { "Add", "Delete", "Update", "Cancel", "Search", "ExcelExport"})">

            <GridFilterSettings Type="Syncfusion.Blazor.Grids.FilterType.Excel"></GridFilterSettings>

            <GridSelectionSettings Mode=SelectionMode.Row></GridSelectionSettings>

            <GridColumns>

                @foreach (var prop in typeof(BusinessObject).GetProperties())

                {

                    <Syncfusion.Blazor.Grids.GridColumn Field="@prop.Name" IsPrimaryKey="@(prop.Name == nameof(BusinessObject.TaskId))"

                                                        AllowEditing="@prop.CanWrite" TextAlign="TextAlign.Right" AutoFit="true"

                                                        HeaderTextAlign="TextAlign.Left" Type="ColumnType.String"

                                                        FilterSettings="@(new FilterSettings { Operator = Operator.Contains })">

                    </Syncfusion.Blazor.Grids.GridColumn>

 

                }

            </GridColumns>

        </SfGrid>

    }

 

</div>

<br />

 

<br />

<style>

    .ulstyle {

        margin: 0px;

        padding-left: 20px;

        display: inline-block;

    }

 

    .e-grid .e-filtermenudiv {

      

        margin: -18px -10px;

     

    }

Hi,

Thank you for your reply

In the DataGrid:

1- How can I create a column like the following?

2- How can I create a tooltip for the image that displays the person's name by moving the mouse over each image.

3- I use filter like excel. Is it possible to display photos in the cells and to display the names of persons in the filter and filter based on the name?

Query :How can I create a column like the following
In your existing code. For your image column, you're using the Template and EditTemplate for rendering and uploading images, respectively. This setup is already correct for creating a column that displays images.

Query:How can I create a tooltip for the image that displays the person's name by moving the mouse over each image?

You can modify the Template of the image column by adding the title attribute to the <img> tag to show the person's name as a tooltip. You can fetch the name from your data context and apply it to the title attribute.

Query “Is it possible to display photos in the cells and to display the names of persons in the filter and filter based on the name?

Yes using the FilterItemTemplate  For your requirement, you can display images in the cells and filter based on the person’s name .Kindly refer to the below code snippet and sample for your reference.

   <SfGrid AllowPaging="true" TValue="Order" AllowFiltering="true" Width="900" Height="350" Toolbar="@ToolbarItems">

    <GridFilterSettings Type="FilterType.Excel"></GridFilterSettings>

 

    <GridEditSettings AllowAdding="true" AllowDeleting="true" AllowEditing="true" Mode="EditMode.Dialog"></GridEditSettings>

 

    <GridColumns>

        @if (Orders != null && Orders.Any())

        {

            foreach (var property in typeof(Order).GetProperties())

            {

                if (property.Name == "Imagesrc")

                {

                    <GridColumn Field="@property.Name" HeaderText="Image">

                        <Template>

                            @{

                                var data = (Order)context;

                                var imageUrl = data.Imagesrc;

                                var personName = data.CustomerID; // Assuming you have person names in the data

                                <div class="image">

                                    <img src="@imageUrl" title="@personName" />

                                </div>

                        <FilterItemTemplate>

                            @{

                                var filterContext = context as FilterItemTemplateContext;

                                var imageUrl = filterContext.Value.ToString();
