Updation problem

Hello Sir,

We have bought Telerik License and we are using Telerik product from a long period of time. Now we want to update our Telerik License so that we are able to use updated version of Telerik with updated controls.But we are facing some problems with the Latest verion. As we are using Trial version of Telerik and while using it we have found that it is being clashed with its previous version.
Issue is that when we upgrade Latest verion of Telerik with the Previous version, it replaces Previous version completely(replaces old DLL with new DLL in same folder) and because of which a lot of problems occurs with the previous controls of Telerik. As Our Software is divided into multiple Exe files and we are using Telerik dll in these files and these are being used in multiple places and we do not want to compile all exe's again with new version. so we are not able to update our License because of the problems with some controls in previous version's exe. Please provide us the solution of this problem so that we can update our Telerik License and using it our Software will run without any problem.

Thank you

UTF-8 in HTML-like formatted cells

Hi, :)

I use a radgridview inside my application where certain words inside of cells should be marked. At the moment I solved this via DisableHTMLRendering and manipulating the data displayed in the cells... for instance with

cellInfo.Value = "<html>" + cellInfo.Value.ToString() + "</html>";

foreach (KeyValuePair<String, Color> kvp in this._highlightWords)

{

cellInfo.Value = Regex.Replace(cellInfo.Value.ToString(), kvp.Key, "<span style=" + '"' + "background-color:" + System.Drawing.ColorTranslator.ToHtml(kvp.Value) + '"' + ">" + kvp.Key + "</span>", RegexOptions.IgnoreCase);

string[] tmpString = Regex.Split(cellInfo.Value.ToString(), kvp.Key, RegexOptions.IgnoreCase);

}

I have a list of words to be marked and I want them to have a colored background... depending on the current word.

Works fine so far, but I do have problems with the encoding. Special characters, like "ä", "ö" are not displayed properly... is there any way to set the encoding?

I already tried to hard-convert my content to utf-8, but that didn't change anything.

byte[] utf8String = Encoding.UTF8.GetBytes(cellInfo.Value.ToString());

cellInfo.Value = Encoding.UTF8.GetString(utf8String);

The data is received from a SQLCE database... am I doing something wrong? Or is this only solvable via the webbrowsercolumns you mentioned in another thread? Will those webbrowsercolumns still be performant, if I do have thousands of them? :)

Thanks in advance!
Kind Regards
Fabian

Telerik check blank row exist

I am currently create an web application to load the selected order in the client transaction record by clicking the copy button in the RadGrid. I implement this by getting the id of the order and retrieve the required entity to insert the form.

JS Runtime Error That Microsoft JScript runtime error: 'document.getElementById(...)' is null or not an object By using MVVM Model , I preset the blank row to be null in terms of the mapped fields such as consumer ID , order ID , consumer Name , Price and so on .

The Order Reference Id is named as referenceOrder and retrieve the LoadReference to insert the record

I am currently using C# , Visual Studio 2012.

What I want to ask is there any methodology to check if the row is blank before the copy action being executed ?

The below is my code

 protected void grdCustomerReport_ItemCommand(object sender, GridCommandEventArgs e)
    {
        // [Start] Declare Grid and GridData.
        RadGrid CurrentGrid = (RadGrid)sender;
        GridDataCustomerReport GridSource = PageSource.GrdCustomerReport;
        //[End] 
        if (e.CommandName == "CustomInsert" &&
            GridSource.state != GridModelState.Edit)
        {
           //Add blank row
        }
        else if (e.CommandName == "DeleteCurrent")
        {
          //Delete Row
            CurrentGrid.Rebind();
        }
        else if (e.CommandName == "Copy") <--I click the button and retrieve the dataset index 
        {
            //Check if there is empty row  ? 

            int referenceOrder ;
            int rowIndex = Convert.ToInt32(e.CommandArgument);

            RadComboBox cbo= (RadComboBox) CurrentGrid.Items[rowIndex].FindControl("cboCode");
            if (cbo.SelectedIndex > 0  && cbo.SelectedValue != "")
            {
                referenceOrder = Convert.ToInt32(cbo.SelectedValue);
                PageSource.SetOrder(referenceOrder );
                LoadReference();
            }
            else
            {
               winAlert.RadAlert("<b>" + "Please Select Reference Orderin the Dropdown List" + "</b>.<br />", 330, 100, "", null);
            }
        }
    }

Load on demand

Hi,

When users need to select from a large list a dropdownlist is arguably not necessarily the best solution. However using teleriks "SuggestAppend" option it is a user friendly option. I'm faced with a patient list which potentially has a few thousand names. Instead of binding the full list, I'd like to bind a subset based on the users input: load on demand.

So far I managed to get things working. The dropdownlist is populated when the user inputs at least 3 characters. I also enabled "SuggestAppend" on the control. I'm using the Key_Up event like this:

/// <summary>

/// Load on demand drop down list

/// </summary>

/// <param name="sender"></param>

/// <param name="e"></param>

/// <remarks></remarks>

private void ddlPatient_KeyUp(object sender, System.Windows.Forms.KeyEventArgs e)

{

//Datasource only changes when user hits a letter

//OrElse e.KeyCode = Keys.Return Then

if ((e.KeyCode >= Keys.A && e.KeyCode <= Keys.Z)) {

//and we have atleast 3 characters

if (ddlPatient.Text.Length > 2) {

//suspend any further keyboard input, untill we're done

ddlPatient.KeyDown += SuspendKeyboard;

string txt = ddlPatient.Text;

//update de dropdown datasource based on the user input (from Open Access model)

ddlPatient.DataSource = _context.Patients

.Where(c => c.Naam.StartsWith(txt) || c.GetrouwdeNaam.StartsWith(txt))

.OrderBy(c => c.Naam)

                                                 .ThenByDescending(c => c.GeboorteDatum)

.Take(100);

//This should be done when initializing the form

//ddlPatient.DisplayMember = "InfoZoekPatient"

//ddlPatient.ValueMember = "PatientID"

//restore the user input and place the cursor at the and of the text

ddlPatient.Text = txt;

ddlPatient.SelectionStart = txt.Length;

//restore keyboard input

ddlPatient.KeyDown -= SuspendKeyboard;

}

e.Handled = true;

e.SuppressKeyPress = true;

}

/// <summary>

/// Catch any keyboard input and ignore it!

/// </summary>

/// <param name="sender"></param>

/// <param name="e"></param>

/// <remarks></remarks>

private void SuspendKeyboard(object sender, KeyEventArgs e)

{

e.Handled = true;

e.SuppressKeyPress = true;

}

The problem is that the selected value of the dropdownlist does not necessarily reflect the user selection? Somehow it gets the value of the first item of the renewed datasource. I've fixed this with the leave event:

/// <summary>

/// When a patient was not selected, but the user enter a search string we need to clean up.

/// </summary>

/// <param name="sender"></param>

/// <param name="e"></param>

/// <remarks></remarks>

private void ddlPatient_Leave(object sender, System.EventArgs e)

{

RadDropDownList ddl = sender;

bool clear = true;

//check if the selected item valuemember equals the ddl text.

if (ddl.SelectedItem != null) {

Patient pat = ddl.SelectedItem.DataBoundItem;

if (pat != null) {

if (ddl.Text.Trim == pat.InfoZoekPatient.Trim)

clear = false;

}

if (clear) {

ddl.SelectedIndex = -1;

ddl.Text = string.Empty;

ddl.SelectedItem = null;

ddl.Update();

}

Now, it works but it seems like a lot of code compared to the ASP.Net control...
Is there an easier way to do this?

Regards,
Raoul

RadMaskedEditBox - Custom Numeric Masks

Hello,

I have some trouble with RadMaskedEditBox using Numeric Masks.
When I use a standard Numeric Mask like "c2" or "N", it's working.
When I try to use any Custom Numeric Mask like "#,##.00 'CHF'" or a simple "0" I'm getting in trouble (can't type anything in the maskedbox !).

My final purpose is to have a mask for Swiss Currency typing (independant of culture, so I can't use the standard currency).
Some examples: "120.00 CHF", "1'420.15 CHF".

I actually use a workaround with the "N2" mask and a label for my "CHF".

Thanks

Databound information and Hyperlink Cell

Hi,

I started trying your RadControls specifically for the use of the GridView hierarchy, but lately have noticed a lot of complications when trying to make the transition from regular DataGridView to RadGridView. One such example:

I have a RadGridView bound to a table on a SQL Server database. Retrieving the information is fine, however, I want to make some cells hyperlinks. Previously, I would write something like this to change my cells from regular TextBoxCells to HyperlinkCells after the binding completed:

for each (Windows::Forms::DataGridViewColumn^ column in dgv->Columns)

{

if(column->HeaderText == "Something"))

{

for each (DataGridViewRow^ row in dgv->Rows)

{

row->Cells[column->Index] = gcnew DataGridViewLinkCell();

}

But I notice there isn't any GridViewHyperlinkCell class or anything similar. How would I go about replicating this behavior? The entire column can be HyperLinkCells. I understand that you can make the entire column of type GridViewHyperLinkColumn, but how would I achieve this dynamically?

EDIT: To accomplish the functionality I described above, I did the following:

Set the GridView property "AutoGenerateColumns" to False
Manually added columns w/ desired column type and set the "FieldName" property to the corresponding column header name in my database table. This directly reflected the table structure in my database.
Set the GridView's "DataSource" to the bindingSource I use to retrieve the table from the database.

This takes the ease out of setting and forgetting, but I couldn't figure out an alternate way.
