hey you can use given code to get value based on row on which you click.
string txt = listView1.Items[listView1.FocusedItem.Index].SubItems[0].Text;
if you need value of both second column you have to change value of SubItems to column index as
string txt1 = listView1.Items[listView1.FocusedItem.Index].SubItems[0].Text;
string txt2 = listView1.Items[listView1.FocusedItem.Index].SubItems[1].Text;
you can also use loop with SubItems for getting value..

Hi,,
I have a Code in VB. Pls Convert this to c# using DeveloperFusion Website.

There is a similar thing i have written for Web.
Group GridView Data[^]
Please check if it could help you. (But it support only 1 level of grouping at a time.)

Google for a drill-down grid. I doubt that there'll be a free version that can be used (with a consistent look) in both web & forms though.
I are Troll

If you're going to use it in web apps, then, try jqGrid for asp.net.

Here is the obvious way (just an example):
byte[] arrARGBValues = { 255, 255, 0, 0, 255, 255, 0, 0, 255, 150, 255, 255 };
int lengthARGBValues = arrARGBValues.Length;
int lengthSubArrays = lengthARGBValues / 4;
byte[] arrAValues = new byte[lengthSubArrays];
byte[] arrRValues = new byte[lengthSubArrays];
byte[] arrGValues = new byte[lengthSubArrays];
byte[] arrBValues = new byte[lengthSubArrays];
for (int i = 0, j = 0; j < lengthSubArrays; i += 4, j++)
{
arrAValues[j] = arrARGBValues[i];
arrRValues[j] = arrARGBValues[i + 1];
arrGValues[j] = arrARGBValues[i + 2];
arrBValues[j] = arrARGBValues[i + 3];
}

when you have an array (or any other collection) of colors, you can manipulate them directly. There is no need to first display them (i.e. their string representation) in a ListBox and then parse those strings, that approach is so wrong.
Here is an example of what one can do, without ListBox, without parsing text:
Color[] colors=new Color[3];
colors[0]=Color.Yellow;
colors[1]=Color.Red;
colors[2]=myImage.GetPixel(0,0);
or
List<Color> colors=new List<Color>();
colors.Add(Color.Yellow);
colors.Add(Color.Red);
colors.Add(myImage.GetPixel(0,0));
...
then
int sumRed=0;
int count=0;
foreach (Color color in colors) {
sumRed+=color.R;
count++;
}
int averageRed=sumRed/count;
see? no ListBox, no strings, no problems. Also less code, and much faster.

oh because my array consist of many entries made up of A, R, G, B. i dont think i can make use of your methods as listed above.

and that is completely silly, why would you mix up things that you later on need separately?
|
|
|
|

in the first place, it is mixed up. tts why i would wanna separate it.

If you are using C# 4 you can do it like this:
string[] argbArray = new string[] { "A=255", "R=255", "G=0", "B=0", "A=255", "R=0", "G=255", "B=0" };
string[] rArray = argbArray.Where(s => s.StartsWith("R=")).ToArray();
string[] gArray = argbArray.Where(s => s.StartsWith("G=")).ToArray();
string[] bArray = argbArray.Where(s => s.StartsWith("B=")).ToArray();
int[] argbintArray = new int[] { 255, 255, 0, 0, 255, 0, 255, 0 };
int[] rintArray = Enumerable.Range(0, argbintArray.Length).Where(i => i % 4 == 1).Select(i => argbintArray[i]).ToArray();
int[] gintArray = Enumerable.Range(0, argbintArray.Length).Where(i => i % 4 == 2).Select(i => argbintArray[i]).ToArray();
int[] bintArray = Enumerable.Range(0, argbintArray.Length).Where(i => i % 4 == 3).Select(i => argbintArray[i]).ToArray();
|
|
|
|
|
am i still able to do this if my array has got 400 entries?
|
|
|
|
|
Either method will work with any sized array...
The first method iterates over each entry in the souce array and pulls out values that start with whatever we are looking for ie "R=" and puts them into a new array.
The second method works like this:
Create an array of integers that represent the indexes in the source array Enumerable.Range(0, argbintArray.Length)
In groups of 4 select every seconds index .Where(i => i % 4 == 1)
Select the items out of the source array at the identified indexes .Select(i => argbintArray[i])
Hopefully that makes sense. Try outputing the result of each step it might help clear up what is happening.

|
|
i will try it out thanks 
|
|
|
|
|
if i do not use c# 4 is there any way i can do it instead?
|
|

Without Linq then using loops like in first reponse by Nuri Ismail is the best approach.

I wanted to get ScrollIntoView(SelectedItem); and highlight the selected item when initialized (tried to manually set the item to the 21st record just for testing purposes). It works fine if I manually select the item but doesn't work if I manually try to set the initial selectitem. This is based onhttp://www.eggheadcafe.com/tutorials/aspnet/5af72df7-5b0b-4ac2-be96-e24127040bbf/wpf-datagrid-as-combobox-dropdown-part-2.aspx[^]
