Hi All,
I am using the below code to retrieve an varbinary image from a database. Is it possible to display the image into an image editor.
Any idea or sample code

SqlConnection conn = new SqlConnection(strconnection);

SqlDataAdapter sda = new SqlDataAdapter("select Front_Image,Rear_Image from Transactions", conn);

DataTable dt = new DataTable();

sda.Fill(dt);

foreach (DataRow row in dt.Rows)

{

//Get the byte array from image file

byte[] imgBytes = (byte[])row["Front_Image"];

//If you want convert to a bitmap file

TypeConverter tc = TypeDescriptor.GetConverter(typeof(Bitmap));

Bitmap MyBitmap = (Bitmap)tc.ConvertFrom(imgBytes);

string imgString = Convert.ToBase64String(imgBytes);

//Set the source with data:image/bmp

Front_img.Src = String.Format("data:image/Bmp;base64,{0}\"", imgString);

Thanks

Paging causes postback when grid setup for client bound data

The grid loads fine using my JSON data source but when I click the paging buttons or page numbers it causes a postback of the page rather than firing a client command event as expected. I dont see a disable postback property.

Here are the relevant information. Its a very simple test.

    <telerik:RadGrid runat="server" ID="RadGrid1" AutoGenerateColumns="False" GroupPanelPosition="Top" Skin="Office2007" EnableViewState="false">
        <MasterTableView AllowCustomPaging="True" AllowPaging="True" PagerStyle-AlwaysVisible="True" PageSize="10">
            <RowIndicatorColumn Visible="False">
            </RowIndicatorColumn>
            <ExpandCollapseColumn Created="True">
            </ExpandCollapseColumn>
            <Columns>
                <telerik:GridBoundColumn DataField="ID" HeaderText="ID">
                    <ColumnValidationSettings>
                        <ModelErrorMessage Text=""></ModelErrorMessage>
                    </ColumnValidationSettings>
                </telerik:GridBoundColumn>
                <telerik:GridBoundColumn DataField="Name" HeaderText="Name">
                    <ColumnValidationSettings>
                        <ModelErrorMessage Text=""></ModelErrorMessage>
                    </ColumnValidationSettings>
                </telerik:GridBoundColumn>
                <telerik:GridBoundColumn DataField="Status" HeaderText="Status">
                    <ColumnValidationSettings>
                        <ModelErrorMessage Text=""></ModelErrorMessage>
                    </ColumnValidationSettings>
                </telerik:GridBoundColumn>
                <telerik:GridBoundColumn DataField="Owner" HeaderText="Owner">
                    <ColumnValidationSettings>
                        <ModelErrorMessage Text=""></ModelErrorMessage>
                    </ColumnValidationSettings>
                </telerik:GridBoundColumn>
            </Columns>
        </MasterTableView>
        <ClientSettings>
            <Selecting AllowRowSelect="True" EnableDragToSelectRows="False" />
            <ClientEvents OnDataBound="dataBound" />
            <ClientEvents OnCommand="RadGrid1_Command" />
        </ClientSettings>

}

What do I miss?

Setting Editmode of Radgrid break select element IE

Hi..

I've tracked a problem down which I initially thought was related to Tabstrip but seems it is actually setting the grid edit mode in code whereby including the lines of code below prevent a select box working in IE 11 on my page. If I comment the lines of code out the select box then works fine. This issue doesn't appear on firefox/chrome though only IE.

                 RadGrid1.MasterTableView.EditMode = GridEditMode.Batch;
                RadGrid1.MasterTableView.BatchEditingSettings.EditType = GridBatchEditingType.Cell;

The procedure simply displays a hidden column and changes the editmode. I'm wondering if the same thing can be done client side? Is there a way in javascript to achieve result?

    if (RadGrid1.MasterTableView.GetColumn("Map").Display != true)
            {
                RadGrid1.MasterTableView.EditMode = GridEditMode.Batch;
                RadGrid1.MasterTableView.BatchEditingSettings.EditType = GridBatchEditingType.Cell;
                RadGrid1.MasterTableView.GetColumn("Map").Display = true;
                foreach (GridColumn col in RadGrid1.MasterTableView.Columns)
                    if (col.UniqueName == "col1" || col.UniqueName == "col2" || col.UniqueName == "col3")
                    {
                        GridBoundColumn boundColumn = col as GridBoundColumn;
                        boundColumn.ReadOnly = true;
                    }
             }

           else
            {
               RadGrid1.MasterTableView.EditMode = GridEditMode.EditForms;
               RadGrid1.MasterTableView.GetColumn("Map").Display = false;
               foreach (GridColumn col in RadGrid1.MasterTableView.Columns)
                   if (col.UniqueName == "col1" || col.UniqueName == "col2" || col.UniqueName == "col3")
                   {
                       GridBoundColumn boundColumn = col as GridBoundColumn;
                       boundColumn.ReadOnly = false;
                   }
            }

GridDateTimeColumn formats dates incorrectly after postback

We have a grid that has a GridDateTimeColumn with the globalization culture info settings set to "en-GB". If I enter the date "30/12/2014" and save it to the database, the column maintains the correct formatting of "dd/MM/YYYY" after the save postback completes. However, if I enter "06/01/2015" and click save, the date format changes to "01/06/2015" after the postback. The date is saved correctly in the db as "12/30/2014" and "01/06/2015".

I'm at a loss as to what the problem could be. Checking CultureInfo and CultureUIInfo shows the following:
CultureInfo = "en-GB"
CultureUIInfo = "en-US"

Internet Explorer's "Language Preference" has only "English (United Kingdom) [en-GB]" in its list.

Even when I set CultureUIInfo to "en-GB" manually in the page_load, the problem persists.

Please help,

Thank you,
James
