team, i have a rad gridview with two combo boxes, the first combo is prepopulated with categories and the second combo box should populate with the subCategories based on the first combo box for each row. Also when an user changes the first combo box value then the second combo box should update its datasource per row.

[Solved] Appointment as solid green bar?

Hi,

Is there a way to make an appointment on the calendar appear as a simple solid green bar (rectangle)?

The rectangle needs to start exactly at the event start time and end at the end time and ideally be without any type of fancy shading/background (just a plain rectangle). Ideally, the width of the rectangle would cover the whole width of the cell (assuming no other appointments overlapping the same time period).

Thanks,

-Lou

Manual CRUD

I need to use manual crud in my context.

How do I get the values of the cells in the row being update.

private void radGridView1_CellEndEdit(object sender, Telerik.WinControls.UI.GridViewCellEventArgs e)

{

//TextBox t1 = RadGridView1.MasterGridViewInfo.CurrentRow.Cells("Company").Value.ToString();

//TextBox t2 = RadGridView1.MasterGridViewInfo.CurrentRow.Cells("something").Value.ToString

{

using (var cn = new SqlConnection(connString))

{

cn.Open();

try

{

SqlCommand cmd = new SqlCommand("UPDATE myTable SET Column = @Parm1 WHERE Col = @Parm2", cn);

var parm1 = cmd.CreateParameter("Parm1");

parm1.Value = t1.Text;

var parm2 = cmd.CreateParameter("Parm2");

parm2.Value = t2.text;;

cmd.Parameters.Add(parm1);

cmd.Parameters.Add(parm2);

int rowsAffected = cmd.ExecuteNonQuery();

}

catch (SqlException ex)

{

//MessageBox.Show(ex.StackTrace);

}

1) The first two lines of code above is what I use to implement in radgrid for asp. How do I get those values in this context winforms?
2) I also have added a delete button column. I do I code the event to delete the row where the button is clicked?

Thanks

Select sql table at run time

Sorry for asking such simple think but for some reasons I am not coming right.
I have a dropdownList that gets populated with the table names:

public void FillDropDownList(string connString)

{

String Query = "SELECT * FROM information_schema.tables where Table_Name like 'Table%'";

using (var cn = new SqlConnection(connString))

{

cn.Open();

DataTable dt = new DataTable();

try

{

SqlCommand cmd = new SqlCommand(Query, cn);

SqlDataReader myReader = cmd.ExecuteReader();

dt.Load(myReader);

}

catch (SqlException e)

{

//TODO

}

radDropDownList1.DataSource = dt;

radDropDownList1.ValueMember = "TABLE_NAME";

radDropDownList1.DisplayMember = "TABLE_NAME";

}

On selectedIndexChanged of the DropDownList I need to fill in the GridView preserving all functionalities (add, update, delete). Basically the table gets choose at runtime. I am not coming right with this and I would appreciate if can point me to a solution or give me a snippet for this.

Thanks

Edit only Node test and not all Node

I wonder how to edit Node text, currently F2 edit all the Node and not only Node text:

radTreeView1.AllowEdit = true;

radTreeView1.BeginEdit();

RadTreeNode ethernetNode = radTreeView1.Nodes.Add("Ip address: 0.0.0.0");

Note that i am not using bound but just regular node creation like in my code example, please see my screenshot, can i edit only my text ? (in my example this is 0.0.0.0)

GridView SaveLayout/LoadLayout not saving ViewDefinition

I have a loaded Gridview with multiple GridViewColumnGroups and I am trying to use SaveLayout/LoadLayout unsuccessfully. I have read ALL the documentation concerning the RadGridView Serialization API but somehow I can't figure out how or even if it's possible.

Can someone shed some light? I'm getting ready to jump out my window!

Thanks!

adding rows is very slow?

I'm trying to add 40 rows in a grid programmaticly like this :

try 

{  

this.Cursor = Cursors.WaitCursor;  

grdSearchResults.SuspendUpdate();  

//remove all filters  

foreach (GridViewDataColumn dc in grdSearchResults.MasterGridViewTemplate.Columns)  

  dc.Filter.StringValue = string.Empty;  

//add new pax to current manifest  

for (int i = 0; i < nb; i++)  

  paxList.AddNew();  

UpdateScreenState();  

grdSearchResults.Rows[paxList.Count - nb].IsCurrent = true;  

grdSearchResults.Columns[0].IsCurrent = true;  

grdSearchResults.GridElement.ScrollToRow(0);  

if (grdSearchResults.CurrentCell != null)  

  ((GridDataCellElement)grdSearchResults.CurrentCell).BeginEdit();  

}  

catch (Exception exc)  

{  

  ExceptionPolicy.HandleException(exc, "Client Policy");  

}  

finally 

{  

  this.Cursor = Cursors.Default;  

  grdSearchResults.ResumeUpdate();  

}

when adding let say 30 rows (nb=30) the grid is extremely slow. Is there something i should do to fasten things up?

I've tried using

grdSearchResults.GridElement.BeginUpdate();

instead of SuspendUpdate but the grid throws an argument out of range exception stating that Value is out of range???
