Very WIDE dropdownlist. using Dynamic data futures!!

Question

User-1759624489 posted

 Hello.

I have  a table called elementcharacteristics, which has a field of type nvarchar(MAX),

 

I have a table called parameters.

 

One elementcharacteristic may have many parameters.

 

The problem is that when I go to the Parameter page, it shows me in a dropdownlist the elementcharacteristics.

 

But that text is too long and the dropdown looks very ugly

 

I was trying to put UIHINT("Text"), but that will not work

 

ANy idea please!!!

 I have a crazy idea but I dont know where to put that code.

 

I put this

   [ScaffoldColumn(false)]
        [Filter(Enabled=false)]
        public object ElementCharacteristic { get; set; }

 

but it doesnt insert, I guess why, because its not sending the ElementCharacteristicId.

 

But I can take that value from the querystring.

 

The problem I dont know exactly where to put that code

 

thx

I solved the problem by adding the following to the filterUserControl

 

  protected void Page_Init(object sender, EventArgs e) {
        if (!Page.IsPostBack) {
            PopulateListControl(DropDownList1);

            for (int i = 0; i < DropDownList1.Items.Count; i++) {
                string s = DropDownList1.Items[i].Text;

                int maxLen = 44;
                for (int j = 0; j < s.Length; j++)
                    if (s[j] > 127) {
                        maxLen /= 2;
                        break;
                    }

                if (s.Length > maxLen) {
                    s = s.Substring(0, maxLen - 2);
                    s += " ... (see Details for full)";
                    DropDownList1.Items[i].Text = s;
                }
            }

            // Set the initial value if there is one
            if (!String.IsNullOrEmpty(InitialValue))
                DropDownList1.SelectedValue = InitialValue;
        }
    }

 It's not a great solution as text area is dependent on local/language.  That should give you a starting point.

Hi, that worked perfect for the  filter, but I need it for inserting-editing.

 I tried this on the Foreign Key Edit

 

 protected override void OnInit(EventArgs e)
    {
        if (DropDownList1 != null)
        {
            for (int i = 0; i < DropDownList1.Items.Count; i++)
            {
                string s = DropDownList1.Items[i].Text;

                int maxLen = 44;
                for (int j = 0; j < s.Length; j++)
                    if (s[j] > 127)
                    {
                        maxLen /= 2;
                        break;
                    }

                if (s.Length > maxLen)
                {
                    s = s.Substring(0, maxLen - 2);
                    s += " ... (see Details for full)";
                    DropDownList1.Items[i].Text = s;
                }
            }
        }  
    
        base.OnInit(e);
    }

 

 

but it still shows me the very WIDE dropdownlist.

 

Thx

I solved my self

 

Moving the code to the page_load and after the populatecontrol method, otherwise it wont work.

 

  protected void Page_Load(object sender, EventArgs e) {
        if (DropDownList1.Items.Count == 0)
        {
            if (!Column.IsRequired)
            {
                DropDownList1.Items.Add(new ListItem("[Not Set]", ""));
            }

            PopulateListControl(DropDownList1);
            if (DropDownList1 != null)
            {
                for (int i = 0; i < DropDownList1.Items.Count; i++)
                {
                    string s = DropDownList1.Items[i].Text;

                    int maxLen = 44;
                    for (int j = 0; j < s.Length; j++)
                        if (s[j] > 127)
                        {
                            maxLen /= 2;
                            break;
                        }

                    if (s.Length > maxLen)
                    {
                        s = s.Substring(0, maxLen - 2);
                        s += " ... (Ver Detalles)";
                        DropDownList1.Items[i].Text = s;
                    }
                }
            }
        }
