Issue with RadGridViewExcelExporter using RadGridview

To summarize what I am attempting to do, I am attempting to export data items from a RadListView (databound) to Excel using a RadGridview and RadGridViewExcelExporter.

This is actually a 2-part issue:
The first issue involves populating with data the RadGridView object that is passed to the RadGridViewExcelExporter (see below).

void Export_to_Excel(String myExcelFile)

{

RadGridView myGridView = new RadGridView();

myGridView.DataSource = myDataSet.joberrors;

RadGridViewExcelExporter exporter = new RadGridViewExcelExporter();

exporter.Export(myGridView, myExcelFile, "Sheet1");

exporter = null;

myGridView = null;

}

myDataSet.joberrors is the datasource of my RadListView and contains 2 rows and 14 columns. Using the above code, myGridView contains 0 rows and 0 columns even after the datasource is set.

To solve this I used

myGridView.LoadFrom(myDataSet.joberrors.CreateDataReader());

now myGridView is successfully populated with data, but the second problem now rears its head...

After exporting the data to Excel using the RadGridViewExcelExporter , the exported worksheet only contains one column - the primary key of myDataSet.joberrors?.

Any ideas what I am doing wrong? Is there an easier way to do this?

Thanks

AutoGenerateHierarchy in GridView

Hi,

I want to use AutoGenerateHierarchy, but I am having a hard time, telling the grid to not show certain columns. I added child templates with the name in the properties of the object being displayed, and marking these columns as not visible, but these templates just get ignored.

How can I control what which columns get displayed when using AutoGenerateHierarchy ?

thanks.

Highlight RadCheckBox when focused

I'm using RadControls for WinForms Q2 2011 (version 2011.2.11.831) and would like to highlight the Checkbox when it has focus to make it easier for my users to find the focused field. I have code working with the Enter/Leave events for RadButtons and RadDropDownLists but am unable to get it working for the RadCheckBox. I've tried using the BackColor/ForeColor properties of the ButtonElement.ButtonFillElement object but to no avail.

Here is my class code for the RadButton:

this.Enter += new EventHandler(BaseButton_Enter);

this.Leave += new EventHandler(BaseButton_Leave);

void BaseButton_Enter(object sender, EventArgs e)

{

this.ButtonElement.ButtonFillElement.BackColor = Color.Blue;

this.ButtonElement.ForeColor = Color.White;

this.ButtonElement.ButtonFillElement.GradientStyle = Telerik.WinControls.GradientStyles.Solid;

}

void BaseButton_Leave(object sender, EventArgs e)

{

this.ButtonElement.ButtonFillElement.ResetValue(LightVisualElement.BackColorProperty, Telerik.WinControls.ValueResetFlags.Local);

this.ButtonElement.ResetValue(LightVisualElement.ForeColorProperty, Telerik.WinControls.ValueResetFlags.Local);

this.ButtonElement.ButtonFillElement.ResetValue(LightVisualElement.GradientStyleProperty, Telerik.WinControls.ValueResetFlags.Local);

}

How can I do a similar effect for the RadCheckBox.

Secondly, I'd actually like to not hard code the colors, but to use the Selected Text Color of the TextBox (I'm assuming this comes from the Theme in use). How do I access the information ?

Thanks,
Chet

RadDropDownList in a GridView

I have a RadDropDownList in a gridview, the Value Changed Event is raised only when I increase/ Decrease the value with the arrows and not when key pressed.

I partially resolved the problem by adding the following code to the Value Changed Event:

GridSpinEditor gseditor = sender as GridSpinEditor;

if (gseditor != null)

{

this.CurrentCell.Value = gseditor.Value;

}

When I press the backspace key the event is raised except if it the last digit.
Any solution?

Thanks,
Dror

Using GridViewDecimalColumn

Hello,

In a gridview, I am using a GridViewDecimalColumn to display numeric data.

The problem is that I would like to be able to use the two arrows key (Up and Down) to scroll on my GridView, and not have my data being increased or decreased when using them. Is there a way to disable the increasing and decreasing of data when using these keys ?

If not, is there a possibility to use another column type (GridViewTextBoxColumn for example) and then, how can I manage it so only numeric values can be typed into it ?

Thank you for your help.

Batch update gridview cells value

is there a way to batch update cell value of a gridview.

I have a situation where i have to loop thru each row and then update one cell value, as shown below. But it becomes really slow when i have large number of records on the grid, so is there any batch update that can be applied. My interface is with a textbox field above the grid and when the user enter text and press apply it has to apply that text to all records on the grid (it could be 100 - 10000 reocords on the grid depending one the search)

foreach (GridViewRowInfo row in radGV_.Rows)

{

row.Cells["BName"].Value = txtBName.Text;

}

RadStatusStrip disable resizing

Hello!

I'm using the RadControls 2011Q2 and I want to disable the ability to resize the Form with the RadStatusStrip. I have already disabled the SizingGrip, though I can resize the Form.

Is there a way using the StatusStrip and the window can only be resized as normal Form-behavior?

Kind regards
