[Solved] How to select a textbox inside a page?

Hello!

If I create a simple RadForm with a single RadTextBox, this text box is selected (gets input focus and shows cursor) automatically when the form is shown. If I create a simple RadForm with a RadPageView and place the RadTextBox into the page, it is not selected automatically when the form is shown.

Even the following code does not select the text box:

protected override void OnLoad(EventArgs e)

{

base.OnLoad(e);

radTextBox1.Focus();

radTextBox1.Select(0, 0);

}

The following workaround does work, but I do not think this is a way I should go:

protected override void OnLoad(EventArgs e)

{

base.OnLoad(e);

Application.Idle += Application_Idle;

}

void Application_Idle(object sender, EventArgs e)

{

Application.Idle -= Application_Idle;

radTextBox1.Focus();

radTextBox1.Select(0, 0);

}

So, how should I correctly select the text box in the PageView page when the form is shown?

Thank you.

SelectedValue and SelectedItem

Hello.

I have a following problem with the combobox:
First I initialize my combobbox: Value column is a numeric field (Int64) , Display column is a Text field:

ddb_Broker.ValueMember = dtBrokerList.Columns[0].ColumnName;

ddb_Broker.DisplayMember = dtBrokerList.Columns[1].ColumnName;

ddb_Broker.DataSource = dtBrokerList.DefaultView;

ddb_Broker.SelectedItem = null;

When I retrieve data I need to populate the Broker:

ddb_Broker.SelectedValue = Convert.ToInt64(gl_dtProgram.Rows[0]["in_broker"]);

after this line in debugger ddb_Broker.SelectedValue = null ..... ? WHY ?

Please, help me to set this value. The same story happened with other fields ..

Thank you ,
Victoria.

Title bar not displaying

I just started my first WinForms app using Telerik controls today, so maybe I'm overlooking something, but my RadForm's title bar will not display. Here's what happens:

I compile and run my app (just one form).
It looks fine, but then I click on another app that brings it in front of mine.
Then I click my app's taskbar button to bring it back... no title bar.

Actually, the title bar is there as in it accepts mouse clicks and I can drag the window, but it doesn't draw itself or the controls on it. It essentially takes a screen shot of what's behind it, then THAT becomes the image of the title bar. That might be some partial text of a web page that was behind it.

This happens w/ VS2K8 on Windows Vista Ultimate x64 and Windows XP Pro x64. The latest service packs for everything is installed and I downloaded and installed Telerik Q1 2009 today.

[Solved] Adding a new RadGridView

I'm having problems when I try to create a new RadGridView. From the toolbox, I select RadGridView and then draw a box on the form. When I do this it adds a reference to the control at the buttom, however it's not actually putting the control on the screen. I checked to make sure that it was visible and the back color was different. This problem has only started happening to me today, before today I could successfully add a RadGridView to my forms.

[Solved] FieldName property of GridViewDecimalColumn does not like a string with two underscores

Hi,

I'm creating a GridViewDecimalColumn as follows:

GridViewDecimalColumn col = new GridViewDecimalColumn();

col.Name = node.Name;

col.FielName = node.Name;

col.HeaderText = friendlyName;

When setting the FieldName property, if node.Name = tb_Column then everything is fine. However, when node.Name = tb_Column_1 then I get a FormatException - Input string was not in a correct format.

Do I need to format that FieldName property in any special way or something?

Thanks

ExcelExportFormatString on GridViewDateTimeColumn does nothing

Ok,

Yet again, another issue that I am facing with the GridView control... :-)

Here are the steps for creating and populating my grid:

1. I construct my columns (mostly, GridViewTextBoxColumn, GridViewComboBoxColumn, GridViewDecimalColumn and GridViewDateTimeColumn) programmatically on form load. First of all, I construct these columns using xml data for the Fieldname properties etc.

Here is an example:

foreach (XmlNode mapNode in mappingXmlDoc.SelectSingeNode("Mappings"))

{

// Maps to GridViewDateTimeColumn

if (elementPrefix == "dt")

{

GridViewDateTimeColumn col = new GridViewDateTimeColumn();

col.Name = mapNode.Name;

col.FieldName = mapNode.Name;

col.HeaderText = friendlyName;

radGridView1.Columns.Add(col);

}

2. After I constructed these columns, I go ahead and initialize the grid by assigning it a datasource. The DataSet in turn is populated with xml data:

DataSet dsData = new DataSet();

dsData.ReadXml(xmlFile);

radGridView.DataSource = dsData.Tables[0];

The xml data that I read into the DataSet looks like this:

<assets>

<asset>

<tb_Desc></tb_Desc>

<dt_MoveDate><dt_MoveDate>

</asset>

</assets>

3. When setting following properties on the GridViewDateTimeColumn as follows:

foreach (GridViewDataColumn in radGridView1.Columns)

{

string[] strArr = col.FieldName.Split(new char[] {'_'});

// This way I know its a GridViewDateTimeColumn

if (strArr[0] == "dt")

{

((GridViewDateTimeColumn)col).ExcelExportType = DisplayFormatType.Custom;

((GridViewDateTimeColumn)col).ExcelExportFormatString = "dd.mm.YYYY";

((GridViewDateTimeColumn)col).FormatString = "{0:dd.mm.YYYY}";

}

nothing happens... I've tried to set the properties both before and after I set the gridview's datasource with no success.

Also, I'm using the ExportToExcelML class for exporting and I always end up with data for the date field looking like this: 1/27/2011 12:00:00 AM in both the grid and exported excel spreadsheet which is wrong.

Is there anything I'm doing wrong somewhere?

I appreciate your help.

Thanks

GridView
