Sorry,

overflow-auto have no effect.

When I insert your grid without container.Only

 

<Grid id=”grid” @ref=”grid” DataSource=”@listGridData” ColumnGroups=”_colGroups” Columns=”@_columns” Paging=”@paging” Pager=”@pager”></Grid>

I have the same problem. After loading the page the Grid width is 100%, but when I inserts later columns in the grid the grid width is greater as the page width.

 

Maybe it is also because the first time I run my BuildGrid function, no data is displayed. The columns are there but no rows are displayed, whereas my list listGridData contains data. If I press the “Anzeigen” button a second time to run BuldGrid. The data is displayed and the width of the table is changed a bit. You can see on the page how the width of the table slowly gets smaller. But in the end it is still wider than the web page.

Here some images.

Image 1 when the page is loaded.

After selection Profil and Timerange and press “Anzeigen” (Show)

 

After I press the Button Aniegen a second time without changes.

I hope the images help you to understand my problem.

 

The editor of the forum show the images, but the images not displayed on the page with the articles!

Hi

Thanks for helping. but it don’t working correctly.

When the page is laoding and the grid is empty than it has a correct width.

After I push a button on the page for loading my grid data from database. I build the gridc olumns dynamically depend of the loaded database data.

The table does not keep its width but grows until all columns in the table are visible.
But the table should keep its predefined width and a horizontal scrollbar should be displayed if not all columns are visible.

 

The div Tag fit to the page width but the grid not with new inserted columns.

Here the code:

<div class=”border border-primary rounded p-2 my-auto bg-light”>
<Grid id=”grid” @ref=”grid” DataSource=”@listGridData” ColumnGroups=”_colGroups” Columns=”@_columns” Paging=”@paging” Pager=”@pager”></Grid>
</div>

<style>
#grid {
width: 100%;
height: 500px;
}
</style>

@code{…}

 

Thanks

 

Alexander

I found my error.

 

For the columns I write the name of the datafields with a first small letter and in my class the members have a big first letter. Sorry
