Auto Populate N/A value on slection of picklist in MSCRM 2011 RRS feed

  • Question

  • Hi,

    I have one requirement like I had one picklist value and 3 text fields
    Picklist  Name : Value Selected (new_valueselected)
    Values : yes (1) , No (2).

    Text Fields : Min ( new_min) , Max(new_max), Others(new_others).

    if I selected the value as NO from the picklist Min, Max and Others value should be N/A.

    If I selected the value as YES I should clear the text.

    I have written the script like this.

    function getValues() {
        var optionsetValueSelected = Xrm.Page.getAttribute("new_valueselected");
        if (optionsetValueSelected == 1) {
            if (Xrm.Page.getAttribute("new_min").getValue() == "N/A") {
            else {
                var MinVal = Xrm.Page.getAttribute("new_min").getValue();
            if (Xrm.Page.getAttribute("new_max").getValue() == "N/A") {
            else {
                var MaxVal = Xrm.Page.getAttribute("new_max").getValue();
            if (Xrm.Page.getAttribute("new_others").getValue() == "N/A") {
            else {
                var OthersVal = Xrm.Page.getAttribute("new_others").getValue();
        if (optionsetValueSelected == 2) {

    Code is working fine but, If I save the record which is having the some values in the text fields,  for example Min = 20 , Max 50, and Others = 15.
    Now When I was slecting the picklist value =  No then text field values are N/A and coming back to Yes values are clearing form the text fields I was unable to retaining the old values of (20, 50 and 15) of the record.

    Please let me know anyone have any idea how to reatin the old values ?

  • Hi,

    setValue - will sets the data value for an attribute. - meaning - it will clear the value at browser level and sets the new value.

    In order to retain the old values, i would suggest you to assign the old values to a temp variable before setting new value, and get old values from temp variable if necessary.

  • You could query back to crm db to get old value because you have not saved so you will be able to access old values.

  • There is no field.getLastValue() for CRM fields.
    This is why you need to use a temporary variable as "Ravitheja J" suggested. The following script is probably close to what you require.

    var lastMin, 
        xrmPage = Xrm.Page,
        ValuesSelected = xrmPage.getAttribute("new_valueselected"),
        Min = xrmPage.getAttribute("new_min"),
        Max = xrmPage.getAttribute("new_max"),
        Others = xrmPage.getAttribute("new_others");
    function getValues() {
        switch(ValuesSelected.getValue()) {
            case 1:
                Min.setValue(Min.getValue() === "N/A" ? lastMin : null);
                Max.setValue(Max.getValue() === "N/A" ? lastMin : null);
                Others.setValue(Others.getValue() === "N/A" ? lastOthers : null);
            case 2:
                lastMin = Min.getValue();
                lastMax = Max.getValue();
                lastOthers = Others.getValue();
