Hi,

You don't have the form therefore there is no automatic submit of the fields (requests don't pass to the server any information)
You have to add the form or pass required information via ExtraParams

I added form and tested it again. still not working. if I remove Autorender='false' in ext:window, then I get error htmlfile:unknow funtime error."t.innerHTML=q(v)
I reposted code below. Hopefully it is better this time.

}.Render(this.winFilter, RenderMode.AddTo); 
 
 
new Ext.Net.TextField()

Hi,

You have to set RenderFormElement = false for the FormPanel or place FormPanel to the Items collection of the Window (in this case the automatically set that property)

    protected void CreateFilterForm(object sender, DirectEventArgs e)
    {
        var f = new FormPanel
        {
            ID = "FormPanel1",
            Padding = 5,
            LabelWidth = 120,
            Height = 220,
            Items = {
               new Ext.Net.TextField()
               {
                   ID = "txtPharmacy",
                   FieldLabel = "Pharmacy (NCPDPID)",
               }
            }
        };

        winFilter.Items.Add(f);
        f.Render();
  
        winFilter.Show();
    }

It works. thanks!!!!!

**vali1993** · Sep 30, 2010, 1:49 PM

Hi I have to reopen this topic. I updated the latest SVN and added the code vladimir suggested. X.GetCmp works great at this scenario
Yet, the code previously worked are throwing error at "eval(result.script)" error is: Microsoft JScript compilation error: Expected ';'
"if(result.script&&result.script.length>0){(functi on(o,result,response){eval(result.script);}).call( window,o,result,response);}"
maybe something I am missing when creating the fieldset and checkbox? thanks for your help!!

add fieldsets and checkboxgroup into each fieldset in code behind

 
for (int i = 0; i < 3; i++)
            {              
                var fs = new Ext.Net.FieldSet();
                fs.Collapsed = true;
                fs.Collapsible = true;
                fs.AutoHeight = true;
                fs.LabelWidth = 1;
                fs.Layout = "Form";              
                fs.ID = "fs"+ i;
                pnlFtypes.Items.Add(fs);
                var ckgroup = new Ext.Net.CheckboxGroup();
                ckgroup.ColumnsNumber = 3;
                fs.Items.Add(ckgroup);
                for (int j = 0; j < 14; j++)
                {
                    var ckbox = new Ext.Net.Checkbox();
                    ckbox.BoxLabel = j;
                    ckbox.ID = "ck" + j;  
                    ckgroup.Items.Add(ckbox);
                }
 }

code to reset checkbox and fieldset where the above error throws.

for (int i = 0; i < 3; i++)
 { 
     for (int j = 0; j < 14; j++)
       {    
         X.GetCmp<Checkbox>("ch"+j).Checked = false;
         X.GetCmp<Checkbox>("ch"+j).Disabled = false;
       }
         X.GetCmp<FieldSet>("fs"+i).Collapsed = true;
 
 }

Hi,

Please provide full test sample. I don't think that your code works correctly because you set the same IDs for checkboxes in the different FieldSets

ckbox.ID = "ck" + j;
