Treeview crash

Hi,

When I move by mistakes a node on the node over him, the application crash with the error bellow.

To reproduce this,
> Create a treeView with 2 nodes inside!
> Move the second node into the first one,
> Do it again (Move the second node that is already into the first one exactly as you did before)

I hope you can reproduce it and tell me how to avoid this problem.

Best regards, Fred

Customize Group By labels in the group panel

Is it possible to customize Group By labels in the group panel?
I've looked and the following example (http://www.telerik.com/help/winforms/gridview-grouping-formatting-group-header-row.html) and it only demonstrated how to customise group heading rows, not the labels in group panel.

Installshield LE and Telerik

Hi all
I downloaded the trial version of 2011Q1 and made some small sample applications in VB.net in VS2010.
Now I want to make a setup project using Installshield 2011 LE available with VS2010.I made a setup project and installed in another machine without any prior rad controls and it was not working.(I took the primary output of my project in the APP folder of Installshield and also added the necessary telerik files like Win.UI.dll,Win.grid,win.themes etc.

Later I made a setup with windows setup and deployment project and it was working perfect.

So can any one shed some light on making an Installshield installer package with telerik components

Kind Regards

Renju

Issue binding to DataSet with two Tables

Hello,
I have a dataset containing two tables. One of the tables is the Customer table and the other one is the customer Purchases table. They have a one to many relationship; each customer can have more than one purchases.
I can't get the RadTreeView to dispay anything related to the Customer or Purchases. They only thing the TreeView displays is the following: System.Data.DataViewManagerListTypeDescriptor. That looks like an error message!?
What am I doing wrong?
I've been struggling with this for an entire day; trying anythign under the sun.
I am using the newest RadTreeView control.

My datbase tables look as follows:

Customer table
====================
ID (autoincrement unique ID)
CustomerName

Purchases table
=============
PurchasesID (autoincrement unique ID)
Customer_ID (foreign key to ID in Customer table)

In the tree view, the customer's purchases should show up underneath each customer's name.
Here is my code:

private void frmMain_Load(object sender, EventArgs e)

{

DataSet ds = new DataSet();

DataRelation relation;

string connectionString = "server=MYSQLSERVER;database=MyStore;uid=FakeUserID;pwd=FakePassword";

SqlConnection mySqlConnection = new SqlConnection(connectionString);

string strCustomer_Query = "Select * from Customer";

string strPurchases_Query = "Select * from Purchases";

try

{

SqlCommand sql_Customer = new SqlCommand(strCustomer_Query, mySqlConnection);

SqlDataAdapter da = new SqlDataAdapter(sql_Customer);

da.Fill(ds, "Customer");

da.SelectCommand.CommandText = strPurchases_Query;

da.Fill(ds, "Purchases");

// Add the relation. Maybe this is not needed because we use the RelationBindings of the RadTreeView

DataColumn parentCol = ds.Tables["Customer"].Columns["ID"];

DataColumn childCol = ds.Tables["Purchases"].Columns["Customer_ID"];

relation = new DataRelation("Customer_Purchases", parentCol, childCol);

ds.Relations.Add(relation);

treeView1.ShowLines = true;

treeView1.RelationBindings.Add(new RelationBinding(ds, "CustomerName", "Customer_ID", "PurchaseID", "ID"));

treeView1.DataSource = ds;

treeView1.DisplayMember = "CustomerName";

treeView1.ValueMember = "ID";

treeView1.ParentMember = "ID";

treeView1.ChildMember = "PurchaseID";

treeView1.ExpandAll();

}

Please help.
Thank you!

How to locate the node needed?

Hello,Telerik
   Really I meet trouble when I use Radtreeview on winform .
   My business is the order including products,and product belongs to one category,category is tree-structure.

But When I want to modify the product detail information,How can I locate the current product Category-ID among the Category Tree..
such as

             ProductDAO productDao = new ProductDAO();
            Product product = productDao.GetProductDetailByProductId(productId);
            tbxProductName.Text = product.ProductName;
            tbxProductNote.Text = product.Remark;
            tbxProductPrice.Value = product.Price.Value;
            tbxProductQuantity.Value = (decimal)product.ProductCount.Value;
            tbxUnit.Text = product.Unit;
            ProductCategory proCategory = productDao.GetCategoryByCategoryId(product.ProductCategoryID.Value);
            GotoSelectNode(proCategory.CategoryName);
My Category Tree is :

private void InitPvProductCategoryTree()
{
ProductDAO proDao = new ProductDAO();

            List<ProductCategory> categorys = proDao.GetAllCategoryList("");
            tbxCategroy.DisplayMember = "CategoryName";
            this.tbxCategroy.ValueMember = "ProductCategoryID";
            this.tbxCategroy.ParentIDMember = "ParentID";
            this.tbxCategroy.DataSource = categorys;

// this.tbxCategroy.DataMember = "Nodes";

Copy data from RadGridComboBoxColumn

Hi, I'm currently implementing Copy to Excel functionality and it works great for all but Combo/MultiCombo columns.

I'm trying to implement it in a generic way so I don't want to cast the data source of the combo and find the value from there. Is there a simple way to reach the Displayed data?

Thanks!

private string ConvertDataToString(bool onlySelectedRows)

{

StringBuilder sbTextData = new StringBuilder();

// Copy columns header

foreach (GridViewColumn col in this.radGridView.Columns)

{

sbTextData.Append(col.HeaderText.Replace("\n", " ") + "\t");

}

sbTextData.Append("\n");

// Convert only selected rows

if (onlySelectedRows)

{

foreach (GridViewRowInfo row in this.radGridView.SelectedRows)

{

int i = 0;

while (i < row.Cells.Count)

{

if (i > 0)

{

sbTextData.Append("\t");

}

if (row.Cells[i].ColumnInfo is GridViewComboBoxColumn)

{

// Obtain displayed data

}

else if (row.Cells[i].Value == null)

{

sbTextData.Append(string.Empty);

}

else

{

sbTextData.Append(row.Cells[i].Value.ToString());

}

i++;

}

sbTextData.Append("\n");

}

else

{

foreach (GridViewRowInfo row in this.radGridView.Rows)

{

int i = 0;

while (i < row.Cells.Count)

{

if (i > 0)

{

sbTextData.Append("\t");

}

if (row.Cells[i].Value == null)

{

sbTextData.Append(string.Empty);

}

else

{

sbTextData.Append(row.Cells[i].Value.ToString());

}

i++;

}

sbTextData.Append("\n");

}

return sbTextData.ToString();

}

Autocomplete logic with 'Contains' instead of 'Starts with' on GridViewComboBoxColumn

Hi, I'm looking for a way to modify the AutoComplete mechanism to filter using 'Contains' instead of 'Starts with' when the user types.

I've seen this functionality is available on the ASP.NET and WPF controls, but haven't found a way to use it or implement it my own way with the WinForms controls.

Thanks!

GridViewComboBoxColumn as a list of values

Hi, I would like to have a ComboBox column in my grid that would be used as a list of values that the user can select, modify or use a new one.

I mapped the ValueMember to a string property of my custom object and set the DropDownStyle to DropDown. It gets saved properly, but I cannot edit the value nor add a 'custom' one.

I can't find a property that let me do that, am I doing something wrong or that functionality is not present?

Also, I would like to be able to add new lines, as it is possible in the GridViewTextBoxColumn but it doesn't seem possible in the ComboBoxColumn.

Thanks!
