Picture column with URL in RadDataGrid

[Zlatko Rusev]

Hello,

My question is how I can use in RadDataGrid a picture column using URL, not image from database

Hi Zlatko Rusev,

You could use GridImageColumn to achieve the required functionality.
       Set the ImageUrl property to a static value in order to appear the same in the entire column. You can set the DataImageUrlFields property to a field in the source that can be used to supply the image path and format it by setting the DataImageUrlFormatString property.

For more information, checkout the part "GridImageColumn" in the following documentation: Column types

Hi Zlatko,

You can use the built-in GridImageColumn for this purpose as presented on the following online demo of RadGrid for ASP.NET AJAX:

Hello Zlatko Rusev,

RadGridView displays images either taken from a database or provided by the developer as Image objects. The rest of the scenario where the images are downloaded from a web site and converted to Image objects is custom and it requires implementation from your side.

If you have additional questions, feel free to contact me.

Hi Nikolay,

Again, my application is Desktop one, and I have to use GridView (?) control for WinForms. It's not web site !
And other question is if a image (source -from directory) has random size, how I can set to be in custom size, and don't want  free apace up & down of its in column cell

Thank you for answer

Hello Zlatko Rusev,

My previous reply was about RadGridView for WinForms. When your images are not contained in a database, but they are contained at a custom directory, you need to create Image objects from them and assign these image objects to the cells in the GridViewImageColumn:

List<Image> images = new List<Image>();

private void Form1_Load(object sender, EventArgs e)
{
    this.customersTableAdapter.Fill(this.nwindDataSet.Customers);

    GetImages();

    GridViewImageColumn imageCol = new GridViewImageColumn();
    imageCol.UniqueName = "Images";
    this.radGridView1.Columns.Add(imageCol);

    for (int i = 0; i < this.radGridView1.Rows.Count; i++)
    {
        this.radGridView1.Rows[i].Cells["Images"].Value = images[i];
    }
}

private void GetImages()
{
    // Fill the images list
}

As to your second question, you can resize an image by creating a new Bitmap from the Image objects that you get from the directory:

Bitmap resizedBitmap = new Bitmap(originalBitmap, new Size(12, 12));

Another option is to set the ImageLayout of the GridViewImageColumn to Stretch. This will make the image fill the cell:

GridViewImageColumn imageCol = new GridViewImageColumn();
imageCol.UniqueName = "Images";
imageCol.ImageLayout = ImageLayout.Stretch;
this.radGridView1.Columns.Add(imageCol);

I hope this helps. If you have additional questions, feel free to contact me.

Hello Luca,

It does not matter where your image is, you just need to assign an Image object as a cell value in the image column:

this.radGridView1.Rows[0].Cells["Images"].Value = Resources.Image11;

I hope this helps.
