Hi Radoslav,

OK, but now, when the grid is displayed again (so after the postback), I loose my style: my cells are not anymore in red.

Is it possible to call the rowexpanded JS function for the current line expanded?

Else, another solution should be, in the grid init event, make again the cells in red, but I did not succeed to reach my "sub grid" cells to make this.

Any ideas?

Once time I will solve this, it should be operationnal. :-)

Thanks again and regards

Damien

Hi Damien,

if you keep this approach 

damienremusat said:

GridSampleSize.Rows.Clear();

this.LoadDS(); //Load the WHDG

You would be able to set which row to be initially expanded like this:

WebHierarchicalDataGrid1.DataBind();

WebHierarchicalDataGrid1.GridView.Rows[0].Expanded = true; 

Make sure that you invoke DataBind before try to access a row or NullReferenceException will be thrown.

Hope this helps.

Hello Rad,

Great Thanks for your help; it helps me in the bigger part.

But one problem remains: What I tried to do is storing a sql statement in an hidden field, then execute this code in server side:

function WebHierarchicalDataGrid1_CellEditing_ExitedEditMode(sender, eventArgs){

var cur_sample_size = document.getElementById('<%=CUR_SAMPLESIZE.ClientID%>').value;

var cur_phase = sender.get_parentRow().get_cell(0).get_value(); var cur_supsize = eventArgs.getCell().get_value();

var cur_point = eventArgs.getCell().get_row().get_cell(0).get_value();

var cur_descript = eventArgs.getCell().get_row().get_cell(1).get_value();

var cur_tol = eventArgs.getCell().get_row().get_cell(2).get_text();

var cur_size = eventArgs.getCell().get_row().get_cell(3).get_value();

var clause_where = "UPDATE %SCHEMA%.MEASSAMPLESIZES SET SUPVAL=" + cur_supsize + " WHERE MAINKEY='%MAINKEY%' " + "AND SAMPLESIZE='" + cur_sample_size + "' AND PHASE='" + cur_phase + "' " + "AND POINT='" + cur_point + "' AND DESCRIPT='" + cur_descript +"'";

document.getElementById('<%=HF_Commit_SupSize.ClientID%>' ).value = clause_where;

//red if out of tolerance

cur_tol = cur_tol.replace(',','.');

var diff = 0;

diff = parseFloat(cur_size) - parseFloat(cur_supsize);

eventArgs.getCell().get_element().style.backgroundColor =

__doPostBack("ctl00_ContentPlaceHolder1_StyleMain1_Module_MeasSampleSize_WebSplitter1_tmpl0_HF_Commit_SupSize", "");

}

And in server side, I run this statement:

protected void Commit_SupSize(){

string SQLQry = "";

SQLQry = HF_Commit_SupSize.Value.Trim();

SQLQry = SQLQry.Replace(

"%SCHEMA%", getProxy.GetBrandName());

SQLQry = SQLQry.Replace(

"%MAINKEY%", this.GetStyleID);

getProxy.RunSQLCommand(SQLQry);

//GridSampleSize.Rows.Clear();

//this.LoadDS(); 

}

Just forgot to tell you that my WHDG is placed in an update panel.

When I exit my cell, I have an asynchronous postback, and this error:

InnerException:
System.NullReferenceException: Object reference not set to an instance of an object.
   at Infragistics.Web.UI.GridControls.GridBot.LoadAdditionalClientState(Object state)
   at Infragistics.Web.UI.GridControls.ContainerGridBot.LoadAdditionalClientState(Object state)
   at Infragistics.Web.UI.Framework.RunBot.HandleRaisePostDataChangedEvent()
   at Infragistics.Web.UI.GridControls.GridBot.HandleRaisePostDataChangedEvent()

   at System.Web.UI.Page.RaiseChangedEvents()
   at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint)

Then, if I add these lines in server side code:

GridSampleSize.Rows.Clear();

this.LoadDS(); //Load the WHDG

I loose the row which was expanded before I exit the cell; in other word, the WHDG has all children row collapsed.

How could I keep my new values and keep my grid view?

Thanks again for your help

Regards

Damien
