View 1 RepliesI want to stop postback if a certain value from a ddl is selected.
I've used VB to create a page whereby if a certain value from a ddl is selected then a hidden panel becomes visible. The problem is the likely answer to a majority of my ddl's is 'No' (or a no type response), however, even though the panel visibility remains false upon selecting No a postback still occurrs, the page refreshes and moves back to the top. I suppose this is a question with 2 possible solutions (or 2 questions rather)
1: Is there anyway of setting postback to false if selected value = No? A typical example of how my code appears is below
[Code]....
(i've used the value '1' to represenet Yes)
2: Is there a way of setting the page position after postback? As you can see in my code above i've set the focus on the next control (being a Radio Button) but i mean, is there an actual way of defining where the scroll bar is set?
I have seen article in code snippet but i have never used web services so that is complicated .

In my web form, i have 2 drop downlist controls. eg. dropdown1 and dropdown2. I will change the dropdownlist1 item, consequently selectedindexchanged event fires and reloads the dropdownlist2 items. And i have another button also in order to get the result based on the dropdown1 and dropdown2. Lets say for example, i have a list of countries in dropdown1 and a list of states in dropdown2. I selected "India" in dropdown1 and correspondingly "Tamilnadu" in dropdown2. And then click a button which calls the dataset based on dropdown1 and dropdown2. The problem i face here is, whenever i click on the button to load the dataset, dropdown1 value remains the same as the dataset is not called again, whereas the dropdown2 value changes to the first one as it gets called automatically during postback. For your information, I have loaded both the lists in the page load using (!IsPostback) property.
My coding is as follows:
protected void Page_Load(object sender, EventArgs e)
{
try
{
if (Session["sesUserName"] == null)
{
Response.Redirect("sessionExpr.aspx", false);
}
else
{
lblStatus.Visible = false;
pnlEvaluate.Visible = false;
if (!IsPostBack)
{
fnLoadDropDown1();
fnLoadDropdown2();
}
}
}
catch (Exception ex)
{
throw ex;
}
}
public void fnLoadDropDown1()
{
dsLoadDD1 = objWebRef.fnLoadOnlineTest();
if (dsLoadDD1.Tables[0].Rows.Count > 0)
{
ddTestTitle.DataTextField = "vchTestTitle";
ddTestTitle.DataValueField = "intTestID";
ddTestTitle.DataSource = dsLoadDD1.Tables[0];
ddTestTitle.DataBind();
}
}
public void fnLoadDropDown2()
{
dsLoadDD2 = objWebRef.fnLoadOnlineTest();
if (dsLoadDD2.Tables[0].Rows.Count > 0)
{
ddUser.DataTextField = "vchUser";
ddUser.DataValueField = "intUserID";
ddUser.DataSource = dsLoadDD2.Tables[0];
ddUser.DataBind();
}
}
protected void ddTestTitle_SelectedIndexChanged(object sender, EventArgs e) ...................
I'm trying to set the selected value of a ddl during page load ie. before databind.
This causes "selected value does not exist" errors. So I force a databind, and add a new element if it does not exist in the data source.
However it looks like when the databind is performed later in the page lifecycle that my added element(s) are removed/overwritten.
Am I setting the values in the wrong part of the life cycle?
I have googled a lot to find any solution to pass the selected dropdownlist item to another page.
In my controller view, I have a got list of of items:
List<SelectListItem> PackagingService = new List<SelectListItem>();
I have a function on page load which will work based on dropdown selected value. and I am using this dropdown in a user control. So getting problem because the dropdown value is not loaded yet before Page Load. How Can I do that using those control still.
Here is my code below.
public partial class GradeEntry : System.Web.UI.Page
{
StudentManager studentManager = null;
CourseManager courseManagerObj = null;
GradeManager gradeManager = null;

Values in multiselect dropdown not getting selected when Select All option is selected for a SSRS dropdown. There are multiple dropdowns on the page. We have one dropdown whose output is being used to populate the second dropdown using a stored procedure. When we check the Select All checkbox on the dropdown then ideally upon page refresh all the values should get selected in the dropdown, but in this case the page refreshes back to the blank dropdown, forcing the user to select the values again. The next dropdown too does not get populated. This makes it impossible to run the report for all the cases by using Select All. We ran the report on differnet database environments. My current location is Mumbai,India, the report worked fine when we ran it on a Bangalore,india database. This issue occurs when we try running it on a Chicago database server. I am using SSRS 2005, SQL2005.

So i tried in Edit:
int CityId_ = objAM.GetCityName(User.CityId);
ViewData["Cites"] = new SelectList(City.GetAllCities(), "CityId", CityName", CityId_);

In the Asp.Net Gridview, I am having a checkbox in each and every row for Printing.
I read and test this code found in this link: [URL]
and works really nice, but I would like to use each checked select row for printing instead of clicking "print" each time I print the row. If I want to print selected checkboxes row, I want to see a window open for printing the checkboxes rows I selected in the gridview.
I also tried this link: [URL]
but doesn't display a new window for printing.
