Row Headers Will Not Hide

[Tom Dennison]

Hi: I have tried several methods and reviewed your examples elsewhere in these forums but have been unsuccessful in hiding the header row. Please see the attached image and code files. What appears in the header are the mapping names for the data used to build the grid. 

Separate note: The "drag files here" feature of this page does not allow text or jpg files. Makes it a bit clunky to share items. 

Thanks

private void InitializeGrid()

{

    this.Dock = DockStyle.Fill;

    this.AutoGenerateColumns = false;

    this.AllowEditing = true;

    this.RowHeight = 200;

    this.AutoSizeColumnsMode = AutoSizeColumnsMode.None;

    this.SelectionMode = GridSelectionMode.Single;

    this.NavigationMode = NavigationMode.Cell;

    // Remove grid borders

    this.Style.BorderStyle = BorderStyle.None;

    this.Style.CellStyle.Borders.All = new GridBorder(GridBorderStyle.None);

    this.Style.HeaderStyle.Borders.All = new GridBorder(GridBorderStyle.None);

    // Enable column resizing - this is the correct property for WinForms SfDataGrid

    this.AllowResizingColumns = true;

    // Add scroll event handler

    this.QueryRowHeight += OnQueryRowHeight;

    // Turn off row headers

    this.ShowRowHeader = false;

    // Adjust size to fit within the parent panel

    this.SizeChanged += (s, e) =>

    {

        if (this.Parent != null)

        {

            var parentPanel = this.Parent.Controls.OfType<Panel>().FirstOrDefault(p => p.Dock == DockStyle.Right);

            if (parentPanel != null)

            {

                this.Width = this.Parent.ClientSize.Width - parentPanel.Width;

            }

        }

    };

}

Hi: I have tried several methods and reviewed your examples elsewhere in these forums but have been unsuccessful in hiding the header row. Please see the attached image and code files. What appears in the header are the mapping names for the data used to build the grid.	Based on the provided information, we understand that you need to hide the header row. This can be achieved by setting the SfDataGrid.HeaderRowHeight property to zero. Code Snippet: this.sfDataGrid.HeaderRowHeight = 0;

Hi - Thank you for the response. I have replaced my existing code of:

this.ShowRowHeader = false;

 With the suggested code of:

  // Turn off row headers

  this.ShowRowHeader = false;

Unfortunately the header row still appears.

Hi  Tom Dennison,

Based on the information provided, we are a little unclear about whether you are trying to hide the RowHeader or ColumnHeader.

We have provided an image of the RowHeader and ColumnHeader, along with details on how to hide both headers.
 

Header	Image	Response
RowHeader		You can hide the Row Header by setting ShowRowHeader to false. Based on this, the Row Header will be hidden properly.   Code Snippet: this.sfDataGrid1.ShowRowHeader = false;
HeaderRow		You can hide the HeaderRow by the SfDataGrid.HeaderRowHeight property to zero.   Code Snippet: this.sfDataGrid.HeaderRowHeight = 0;

Hi: Sorry for the confusion. Yes, I am in fact trying to hide the header row. I have implemented the code to set the size to zero but the issue remains. I am doing this in initializeGrid which is called from the constructor. If you would like to see the entire section of code I can provide it. Do you have a secure method to upload it?

Hi Tom Dennison,

Based on the information provided, we understand that you are trying to hide the header row of the SfDataGrid. We have prepared a sample based on the code snippet from the initial update, but we were unable to reproduce the issue. In our test, the header row was hidden properly.

To assist you further, we kindly request the following additional details:

• Can you share your data settings for SfDataGrid?
• Modified Sample: If possible, modify the attached sample to reproduce the issue and share it with us.

These details will help us better understand the problem and provide a timely resolution.

Note: You can share your code files in this forum. Please zip your code files and attach them.

Attached is my code file. I will look at the sample you provided. Thanks!

I am not sure if the file uploaded so here it is again.

Hi Tom Dennison,

Thank you for sharing your code file. We have reviewed it and attempted to replicate the issue, which was successfully reproduced.

Upon analyzing your code, we noticed that you have set HeaderRowHeight to zero and handled the QueryRowHeight event. Within this event, you check if the RowIndex is greater than zero and perform certain operations. However, you are directly setting e.Height to rowHeight, which also affects the HeaderRow.

To fix this issue, we recommend that you avoid setting the height for the HeaderRow within the QueryRowHeight event.

We have prepared a simplified sample with the modified code snippet. Please take a look at the code snippet and sample below, and let us know if it fixes your issue.

Code Snippet:

private void OnQueryRowHeight(object sender, QueryRowHeightEventArgs e)

{

    if (e.RowIndex > 0)

    {

        if ((this.RowCount - e.RowIndex) < 5 && _imageCollection != null)

        {

            _imageCollection.LoadNextBatchIfNeeded();

        }

    }

    if (e.RowIndex > 0)

    {

        e.Height = this.RowHeight;

        e.Handled = true;

    }

}

Thank you for your cooperation and understanding.

Hi: removing the e.Height = thisRowheight did the trick. I was unaware that setting the row height would also impact the header, especially if I had set it to zero.  

Thank you for looking into this for me.
