How to "find" a radtoolbar in a radgrid

I have this layout:

<RadGrid>
   <MasterTableView>
      <CommandItemTemplate>
         <RadToolBar>

How can I "find" the radtoolbar to disable buttons? I can do a "myControl.FindControl("myGrid")... but i cannot find the toolbar do enable/disable it. I can also do a grid.MasterTableView.GetColumn("myButton").Visible = false but again, can't seem to "find" the toolbar or it's buttons.

Any help?

Thanks

Setting MaxLength for Autogenerated Edit and Insert Text Boxes

This gave me fits, perhaps it can be useful to someone else.

The problem was that I have one page where the user can select from a drop down to edit one of a number of different reference tables in the grid. They select a table, and the datasource and grid are rebound to that particular table.

Part of the problem then is limiting their input to the proper length for each field.

Unfortunately the sqldatasource doesn't preserve the underlying SQL types, at least not that I could find. It converts varchars to a "string" type. So there is no field length available.

So we retrieve the schema data separately from the DB. Where lstReference is the list box they select the table to edit from, and the value contains the table name. Note that it's only getting the length for the varchar and nvarchar fields. Those are the only ones I'm interested in here, but you could certainly modify that to your needs.

private void GetSchema()

{

// Clear the list out.

_charFieldLength.Clear();

DataTable dt = new DataTable();

string connString = Util.GetConnectionString();

SqlConnection conn = new SqlConnection(connString);

conn.Open();

try

{

// Retrieve the schema info from the DB.

string[] restriction = { Util.GetDBName(), null, lstReference.Items[lstReference.SelectedIndex].Value, null };

dt = conn.GetSchema("Columns", restriction);

}

catch (Exception ex)

{

// Log error

}

finally

{

if (conn.State == ConnectionState.Open)

conn.Close();

}

// Populate the list with the schema info we're interested in.

foreach (DataRow row in dt.Rows)

{

if (row["DATA_TYPE"].ToString() == "varchar" || row["DATA_TYPE"].ToString() == "nvarchar")

{

FieldInfo fi = new FieldInfo();

fi.FieldName = row["COLUMN_NAME"].ToString();

fi.DataLength = int.Parse(row["CHARACTER_MAXIMUM_LENGTH"].ToString());

_charFieldLength.Add(fi);

}

And we can store that information in a list of these structs, just the field name and length.

private struct FieldInfo

{

public string FieldName;

public int DataLength;

public FieldInfo(string fieldName, int dataLength)

{

FieldName = fieldName;

DataLength = dataLength;

}

List<FieldInfo> _charFieldLength = new List<FieldInfo>();

And this took me a while to weed out, but I did find a Telerik example that I was able to finally use to get a reference to the auto generated edit text boxes to be able to actually set the MaxLength. This works for both Edit and Insert.

protected void gridActivity_ItemDataBound(object sender, GridItemEventArgs e)

{

if (e.Item is GridEditableItem && e.Item.IsInEditMode)

{

GridEditableItem form = (GridEditableItem)e.Item;

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

{

TextBox dataField = (TextBox)form[_charFieldLength[i].FieldName].Controls[0];

dataField.MaxLength = _charFieldLength[i].DataLength;

}

Using RadGrid as part of a composite server control

I am not sure if that will be the right place to ask.
I am writing a asp.net composite server control, which will have a RadGrid as part of it. I don't want to expose the whole grid as a public property though, instead I would like to expose just GridColumnCollection part.

GridColumnsCollection is a read-only property though so I can't write the code below:

[

Category("Grid"),

Description("Columns for a grid."),

DesignerSerializationVisibility(DesignerSerializationVisibility.Content),

PersistenceMode(PersistenceMode.InnerProperty)

]

public GridColumnCollection GridColumns

{

get

{

EnsureChildControls();

return grid.MasterTableView.Columns;

}

set

{

EnsureChildControls();

grid.MasterTableView.Columns = value;

}

When I am trying to change it to something like the code below, I will get an error saying that GridColumnCollection does not have constructor which takes 0 arguments.

[

Category("Grid"),

Description("Columns for a grid."),

DesignerSerializationVisibility(DesignerSerializationVisibility.Content),

PersistenceMode(PersistenceMode.InnerProperty)

]

public GridColumnCollection GridColumns

{

get

{

EnsureChildControls();

return grid.MasterTableView.Columns;

}

set

{

EnsureChildControls();

foreach(GridColumn col in value)

{

grid.MasterTableView.Columns.Add(col);

}

Is there any way to expose just columns from RadGrid as a property of a composite server control?

Thanks,

Daniel

RadGrid with GridTemplateColumn with Radcombobox bind programmatically

Hi,
I explain my situation.
I have a grid with many template columns.
One template column (uniquename: "ValoreTextBoxComboBox") has two controls a label ("LabelDescrizioneI") binded and a radcombobox ("RadComboBoxValore") not binded.
Then programmatically "OnItemDatabound " event of the radgrid i decided which control is visible and in case this control is the radcombobox i bind it.
Everything works until i click "Edit" on the radgrid, the combobox lost everithing ( data and selectedvalue) .

else

}

I really don't understand why the radcombobox lost everithing when i click the Edit column. I used the same tecniche to fill the combo if " IsInEditMode" or if (e.Item is GridDataItem).

Thanks everybody !!!!

problem on filtering when comma separator used

Hi all,

I am using comma for the thousands separator (like 5,000) into the numeric columns.
When I filter this value by writing the value with comma (like 5,000) into the filter box, I got an error message. Filtering without a comma (like 5000) works.

The users will filter the values writing commas so I need to solve this issue. Can you please help me?

Thanks,
