View 2 RepliesI am in the process of building a calorie calculator. I have a calculation ready to test but I am having trouble getting it to print as onto a blank label. Here is what I have so far. I just need to figure out how to print "maintainanswer" back to the user.
View 1 RepliesI am exporting only two columns to the excel
"Amount" and "Out Of 10 Percent".
I will enter the amount in "Amount" column and "Out Of 10 Percent", i will display the 10 Percent of the amount
Say Amount Out Of 10 Percent
1000 100
100 10.
I can do the calculation in C# and i can able to export the content to excel as above.
My need is in the exported excel, if change the amount means i should able to get the corresponding amount in the next column.
(i.e) in the exported excel, if i edit the "Amount" ->1000 to 500 means the next column "Out Of 10 Percent" should change as 100 -> 50. I mean it should be auto calculated in the exported excel.
I need to do calculation of different no as shown in fig..right now i am doing addition in the normal way...adding all the values of the textboxes and thenn showig the result in the last textbox..what i want is whenever i change any value in the any textboxes it should automatically reflect the changes in the final calculation(final textbox) without using calculate button.

In a formview I need to present a new value calucalted by dividing one field value by another. I need to present the result to one decimal place. The code I am using is the following, however it presents the resulting value rounded up or down to the nearest whole value:
<asp:label id=lblTotal text='<%# Convert.ToInt32(Eval("Value1")) / Convert.ToInt32(Eval("value2")) %>' runat="server"></asp:label>
I did try and insert refernces to {0:N1} but this just threw asp.net errors. Any advise on how I can guarantee that the value calculated is presented to one decimal place?
I'm not sure how to do this, but I did read a lot of post and searched for it.

Modal not showing up when show is called, also error on loading page. Attaching code below, can anyone help me discover my syntax / logic issues here?
NOTE: Did some research on this before posting, some claimed it can be an issue of where the modal is placed on the page in relation to the update panel I am using. I have tried different placements of the modal extender and I also tried removing the update panel all together in hopes to at least see the modal show, no go...same issue. So with that, the issue shouldnt be around the use of the update panel...

It basically is 4 questions with each answer assigned a value.
What I would like to do is when the button is clicked the selected values are retrieved and calculated to give a total.
That total is then compared against some common totals and the next value is shown.
So is the total is 8= Very Good, 6= Very Bad, 4= Terrible etc.
The two labels Result and Truth would sho the numerical result and the truth according to the scale.
I am at a loss on how to retrieve the list button clicked value, how to add them up and referance that to the Truth result.
its complicated (to me its "bang head against wall" difficult.
.NET noob here (as in I know next to nothing, I'm trying to pick up some of the scraps left by my developer). Ok, I am getting this error on a number of my .aspx pages: Error while checking url '/': Key cannot be null. Parameter name: key Interestingly, I get this on my homepage on which the only .NET code is in the form of two includes, e.g: <% Response.WriteFile("/includes/footer.aspx") %> These includes in themselves only contain HTML, so I assume the issue can only be related to these or a configuration issue?
