ShowDropDown problem

I am using a RadDropDownList (Q2 2011) as a search box to find a student. The user types in a name into the RadDropDownList and either hits the enter key or clicks a button.

I am using the KeyPress event to test for the enter key. Both the KeyPress event and the button click event call a FindStudent routine.

The FindStudent routine retrieves data from a database and populates the RadDropDownList using a for loop and adding an object to the list with .Items.Add method. At the end of the routine it calls the ShowDropDown() method.

If I type in the RadDropDownList and click on the button, the drop down shows correctly. If I type in the RadDropDownList and hit the Enter key the drop down shows and then immediately disappears.

How can I get the drop down to stay when hitting the enter key? Thanks for your help.

Below is my code for the KeyPress event, Button Click event and FindStudent routine.

private void FindStudent_Btn_Click(object sender, EventArgs e)

{

string fsText = FindStudent_DDL.Text;

FindStudent_DDL.Items.Clear();

FindStudent(fsText);

}

private void FindStudent_DDL_KeyPress(object sender, KeyPressEventArgs e)

{

if (e.KeyChar == (char)13)

{

string fsText = FindStudent_DDL.Text;

FindStudent_DDL.Items.Clear();

FindStudent(fsText);

}

private void FindStudent(string fsText)

{

... code that retrieves data from database and populates a DataTable dt ...

if (dt.Rows.Count > 0)

{

for (int i = 0; i < dt.Rows.Count; i++)

{

StudentObject student = new StudentObject(dt.Rows[i]["id_num"].ToString(), dt.Rows[i]["last_name"].ToString(), dt.Rows[i]["first_name"].ToString());

FindStudent_DDL.Items.Add(new RadListDataItem(student.ToString(), student));

}

FindStudent_DDL.ShowDropDown();

}

Custom dictionary and suggested words

Hi,

I have a problem while using the spellcheck feature for RadRichTextBox.

I'm loading a custom dictionary using the following command line:

CType(Me.RadRichTextBox1.SpellChecker, DocumentSpellChecker).AddDictionary(dictionary, CultureInfo.InvariantCulture)

Then, I set the IsSpellCheckingEnabled as True.

The spellchecker does not recognize the words in the dictionary file.

The misspelled words are underlined, but suggested words do not show up when I click the misspelled word. How can I get the suggested word to show up?

resize problem by autoscroll

Hello,

I have a problem with the RadSplitContainer. I would like to place more sizable panels in the RadSplitContainer.

If the AutoScroll of RadSplitContainer is true and I scroll the container a little, don’t work the resizes of the panels.

How can I resize the panels after scroll?

Is it a bug in the RadSplitContainer? If yes, is there a workaround to this?

Below is the sample code

Thanks

public partial class Form1 : Form

{

public Form1()

{

InitializeComponent();

RadSplitContainer radSplitContainer1 = new RadSplitContainer()

{

Dock = DockStyle.Fill,

AutoScroll = true

};

this.Controls.Add(radSplitContainer1);

for (int i = 0; i < 10; i++)

{

var panel = new SplitPanel();

panel.SizeInfo.SizeMode = SplitPanelSizeMode.Absolute;

panel.SizeInfo.AbsoluteSize = new Size(100, 0);

radSplitContainer1.SplitPanels.Add(panel);

}

Exporting hierarchical grid w/ visuals

Hi all,

I have a hierarchical grid that I am trying to export to excel using ExportToExcelML. Export Hierarchy is on and when I have ExportVisualSettings set to false, the export works perfectly in < 2 seconds. However when I turn the export visuals property on, the grid freezes and the form stops responding.

I have a few special visual components I use in my grid and I'm wondering if any of them may cause this behavior:
-Cells with BackColor set based on the value in the cell (values are hex rgb strings)
-DropdownColumns that also set the backcolor of each cell
-AlternatingRowcolor is set to true

Any ideas?
Alex

Combine SelfReference and ColumnGrouping

Hi,
I would like to have a SelfReference grid with grouped columns. I used the self reference example from the demo application as a starting point. After implementing the column grouping only the top level columns are shown and no "+" symbol is visible. When self reference is turned off all rows are visible.
Is it possible to combine self reference and column grouping? Is there some difference for self reference when using grouped columns?
Thanks.
