Persistence is not working in a stable way.

Hi there
Persistence is not working in a stable way.
Maybe it works the first time (if you do not resize too many columns (eg 4)) maybe it works ok the second time, then it resets to original state.
There is also a problem when collapsing one column over the previous one by resizing it.
Then, there is no way to rearrange the collapsed column or the column which this column is collapsed to...
Which brings to the necessity of some functionality of a method to bring the grid back to its original settings (when user have the grid messed up).

Thanx a lot!

Hi Rijakis,


Greetings from Syncfusion support.


We have checked your query and before proceeding further with your requirement kindly share the below details to validate further from our end.


  1. Share us the entire Grid code snippet.
  2. Share us whether you have used EnablePersistence/ handled persistence manually.
  3. Share us the video demonstration of the issue explaining your query.
  4. If possible share us the issue reproduceable sample.


The above-requested details will be very helpful for us to validate the reported query at our end and provide the solution as early as possible.


Regards,

Monisha

Hi there.
I am sending you the sample.

I am also sending you two videos.

The first one displays the problem of keeping the column sizes to the user settings.
By making this video I discovered that the problem is taking place only if you change the size of the last column.
If the last column is not at the end of the grid, the settings are lost, or the columns are resized so that the grid is ...full by them.

The second video shows the problem with collapsing one column size over another (setting its width practically to zero).
The collapsed column after that is unreachable in any way.
It is still "visible" (you cannot somehow unhide it) and you cannot take it and resize it from then on.
The only way I found this column to reappear is to change the Grids [ID] in code so it will reset to code widths.

Resetting to the original (code) widths and other settings, should be an option that the user should have at his disposal, so that if he messes up with settings, he can reset them to programmer's default.

*I put the videos into the rar because it wouldn't let me upload them.

Until then we appreciate your patience.

We suggest you to set MinWidth at column level. So that we can prevent collapsing the column during resize. Kindly refer the attached code snippet and UG for your reference.


<SfGrid ID="Grid20" DataSource="@Orders" AllowPaging="true" EnablePersistence="true" AllowResizing="true"

        Height="200" @ref="Grid">

 

 

    <GridColumns>

        <GridColumn Field=@nameof(Order.OrderID) HeaderText="Order ID" TextAlign="TextAlign.Right" MinWidth="120" Width="200" MaxWidth="300"></GridColumn>

        <GridColumn Field=@nameof(Order.CustomerID) HeaderText="Customer ID" MinWidth="8" Width="200"></GridColumn>

        <GridColumn Field=@nameof(Order.OrderDate) HeaderText=" Order Date" Format="d" Type="ColumnType.Date" TextAlign="TextAlign.Right" MinWidth="8" Width="200"></GridColumn>

        <GridColumn Field=@nameof(Order.Freight) Format="C2" TextAlign="TextAlign.Right" MinWidth="8" Width="150"></GridColumn>

 

    </GridColumns>

</SfGrid>

Hi there.
Thanx for the reply.

One more question in the second issue.
Where does the component save the settings in the browser? 
How can I delete them?

Hi Rigakis,


Welcome.


Query: “Where does the component save the settings in the browser? How can I delete them?”


We would like to inform that the persisted data is stored in local storage. We don’t have direct support to delete the data present in the local storage. Instead you can clear the persisted data by using ResetPersistData method of DataGrid. Kindly check the attached UG for your reference.

This is exactly what I need it.
Thanks a lot!

Now I'm trying to add in the column context menu the option to " ResetPersistData"

I cannot find information about the "Target" option of "ContextMenuItemModel".
I found out that ".e-content" is for the body of the Grid, but i cannot find anywhere what value refers to every section in the grid (particularly column header) 
Documentation just says it's type of string...

Hi Rigakis,


Thanks for the update.


Query: “I cannot find information about the "Target" option of "ContextMenuItemModel". I found out that ".e-content" is for the body of the Grid, but i cannot find anywhere what value refers to every section in the grid (particularly column header) ”


We suggest you to use .e-header class for header section. Kindly refer the attached code snippet and sample for your reference. For additional information Kindly refer the attached code snippet and sample for your reference.



 

<SfGrid @ref="DefaultGrid" ID="grid1" AllowFiltering="true" EnablePersistence=true DataSource="@Orders" AllowPaging="true" ContextMenuItems="@(new List<ContextMenuItemModel>() { new ContextMenuItemModel { Text = "Reset Persist Data", Target = ".e-header", Id = "reset" } })">

    <GridEvents ContextMenuItemClicked="OnContextMenuClick" TValue="Order"></GridEvents>

</SfGrid>

 

@code{

 

    public void OnContextMenuClick(ContextMenuClickEventArgs<Order> args)

    {

        if (args.Item.Id == "reset")

        {

            this.DefaultGrid.ResetPersistDataAsync();

        }

    }

}
